It's a record that's invisible to the naked eye, written in quantum dots that emit near-infrared light readable by a modified smartphone. But the technology raise several ethical concerns that could stymie its progress. trailer "It's possible someday that this 'invisible' approach could create new possibilities for data storage, biosensing, and vaccine applications that could improve how medical care is provided, particularly in the developing world," Langer says. Directions. 7.. 0000012564 00000 n The next step, McHugh says, is to test a similar protocol in longer-lived animals like pigs, which share a lot of anatomical commonalities with humans, including the structure of their skin. To create an "on-patient," decentralized medical record, the researchers developed copper-based quantum dots, which emit light in the near-IR spectrum. They tagged each G protein with luciferase, an enzyme that interacts with a protein called luciferin to release light. 0000004430 00000 n Furthermore, Rao and colleagues were able to exploit the fact that quantum dots with distinct emission spectra all have similar absorption profiles allowing all of them to function as luciferase energy acceptors. McHugh and former visiting scientist Lihong Jing are the lead authors of the study, which appears today in Science Translational Medicine. The patch is then removed, leaving behind a subtle mark that can still be imaged after being exposed to the equivalent of five years worth of sunlight, the teams experiments show.

When the patch is applied to the skin, the microneedles, which are 1.5 mm long, partially dissolve, releasing their payload within about two minutes. Vaccines delivered with microneedles also may not need to be refrigerated, reducing both the cost and difficulty of delivery, Langer and Jaklenec say. 0 The researchers designed their dye to be delivered by a microneedle patch rather than a traditional syringe and needle. Every lost sheet of paper or inaccurately tallied statistic can raise a persons risk of receiving inadequate carean especially pressing issue in low- and middle-income countries, where health care resources are often scarce or inaccessible. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in McHugh et al., Science Translational Medicine (2019). At the root of it all, the tattoos still address a very important problem, Hoyt says. McHugh et al., Science Translational Medicine (2019). Longitudinal in vivo imaging using a smartphone adapted to detect NIR light demonstrated that microneedle-delivered QD patterns remained bright and could be accurately identified using a machine learning algorithm 9 months after application. Temperature dependent fluorescence of CuInS/ZnS quantum dots in near infrared region. startxref Quantum Dots Deliver Vaccines and Invisibly Encode Vaccination History Epub 2019 Jul 11. 0000006410 00000 n Present affiliation: BioHealth Innovations Inc., Rockville, MD 20850, USA. If the teams research progresses, future efforts will focus on delivering the technology to children in low- and middle-income countries, where many still rely on paper cards or certificates to track their vaccination history. In order to be protected against most pathogens, one needs multiple vaccinations, Jaklenec said. Fig. Science & Research (Biologics), Recalls, Market Withdrawals and Safety Alerts, Luciferase Immunoprecipitation System (LIPS) assay is a rapid, simple, and sensitive test to detect antibody response to respiratory syncytial virus. et al. Endo Inks Collaborations in Pain and Cancer, Orexo to Take Over PharmaKodex to Enhance Reformulation Business. Like QR codes, these designs could be scanned and interpreted by smartphones, and someday allow health providers to archive and access patients past vaccinations without the muss and fuss of external records. BBC News reporter Lina Zeldovich spotlights how MIT researchers have developed a way to store a patients vaccine history under a persons skin using microneedle patches. Bringing in the voices and opinions of the people who stand to benefit the most from the product is something that should start early, and continue. Specialized dye, delivered along with a vaccine, could enable 'on-patient' storage of vaccination history. And when the team scanned the rats nine months later, they could still identify the symbols the microneedle patch had left. Solving medicines record-keeping riddle, they argue, might just involve injecting patterns of invisible nanoparticles under the skin. Biocompatible near-infrared quantum dots delivered to the skin by "In areas where paper vaccination cards are often lost or do not exist at all, and electronic databases are unheard of, this technology could enable the rapid and anonymous detection of patient vaccination history to ensure that every child is vaccinated," says Kevin McHugh, a former MIT postdoc who is now an assistant professor of bioengineering at Rice University. This study confirmed that incorporating the vaccine with the dye in the microneedle patches did not affect the efficacy of the vaccine or our ability to detect the dye, added Ana Jaklenec, a research scientist at MITs Koch Institute for Integrative Cancer Research. Present affiliation: ATCC Cell Systems, Gaithersburg, MD 20877, USA. 2022 Sep 14;25(10):105014. doi: 10.1016/j.isci.2022.105014. the Science X network is one of the largest online communities for science-minded people. Fig. | READ MORE. Quantum Dots Encode Vaccine History in the Skin - IEEE Spectrum "Then there will be quantum dot micro-needles, a DIGITAL IDENTIFICATION MARK in the form of a dye under the skin, a sort of tattoo that can be detected with special light and/or scanners. The researchers also wanted to avoid technologies that would raise even more privacy concerns, such as iris scans and databases with names and identifiable data, she says. By delivering both agents in the same microneedle patch, there is the potential to realize production cost advantages and eliminate the possibility of misuse (such as applying the encoding patch without the vaccine) Ultimately, we believe that this invisible, on-body technology opens up new avenues for decentralized data storage and biosensing applications that could influence the way medical care is provided, especially in the developing world., This is wonderful, helpful, awesome, medical technology but we all know very well intended technology like this can eventually be used for more control over humans 0000010192 00000 n Because these phones offer on-board processing power, camera applications, and inexpensive consumer-grade camera modules, we chose to adapt an existing smartphone to enable NIR imaging rather than build a completely new imaging system, they wrote. But the teams experiments in rats suggest that these medical marks are both safe and long-lasting, and can be administered alongside vaccines without compromising efficacy. Are Organoids the Future of Drug Discovery? Thats really the biggest challenge that we overcame in the project, Jaklenec says, adding that the team tested a number of off-the-shelf dyes that could be used in the body but could not find any that endured when exposed to sunlight. The dots are about 4 nm in diameter, and are encapsulated in biocompatible microparticles that form spheres about 20min diameter. Nat. 0000145250 00000 n The quantum dots are composed of nanocrystals, which emit near-infrared (NIR) light that can be detected by a specially equipped smartphone. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. Quantum dot excitation light has wide band range, narrow emission spectrum width, high fluorescence intensity, good stability, long life and certain antibacterial activity (Ren et al., 2020), which makes it have a good application prospect in wound healing (Salleh and Fauzi, 2021), drug transport (Fakhri et al., 2017), fluorescent biosensors . Such patches are now being developed to deliver vaccines for measles, rubella, and other diseases, and the researchers showed that their dye could be easily incorporated into these patches. 0000023918 00000 n This site needs JavaScript to work properly. Science Translational Medicine (2019)]Experiments in live rats confirmed that the microneedle patches could also successfully deliver a polio vaccine at amounts generated therapeutic antibody levels. A faculty member at MIT Sloan for more than 65 years, Schein was known for his groundbreaking holistic approach to organization change. 0000003562 00000 n 0000005778 00000 n 18 0 obj <> endobj Please enable it to take advantage of the complete set of features! We want people to be comfortable, says study author Kevin McHugh, a bioengineer at Rice University. In theory, each symbol could denote a different type of injection, McHugh says, and be read through a simple machine learning algorithm that the teams already written and tested.

U.S. Customs OIT to relocate headquarters to Ashburn | News By conjugating luciferase protein to quantum dots, bio-luminescence resonance energy transfer (703) 886-5600. Main Quantum. The problem is compounded because many vaccines, such as the vaccine for measles, mumps, and rubella (MMR), require multiple doses spaced out at certain intervals. The reason was probably that the firefly luciferase is very fragile and sensitive to any chemical modification. RSV also affects many elderly individuals, especially those with underlying heart or lung disease, accounting for nearly as many hospitalizations as influenza.

By selectively loading microparticles into microneedles, the patches deliver a pattern in the skin that is invisible to the naked eye but can be scanned with a smartphone that has the infrared filter removed. 0000002622 00000 n Lim M , Lee W , Bang G , Lee WJ , Park Y , Kwon Y , Jung Y , Kim S , Bang J . 0000024059 00000 n Terms of Use The MIT senior will pursue graduate studies in earth sciences at Cambridge University. McHugh and former visiting scientist Lihong Jing are the lead authors of the study, which appears today in Science Translational Medicine. It remains to be seen if these microneedle patches fit the bill. 0000014465 00000 n sharing sensitive information, make sure youre on a federal I would like to subscribe to Science X Newsletter. 0000105025 00000 n 0000010079 00000 n They are also working on expanding the amount of data that can be encoded in a single pattern, allowing them to include information such as the date of vaccine administration and the lot number of the vaccine batch. Different people and different cultures will probably feel differently about having an invisible medical tattoo.. With this aim, researchers at Massachusetts Institute of Technology have developed a microneedle patch containing a nanocrystal dye that creates near-infrared-emitting dots under the skin. One of the biggest issues, Lee says, involves privacy, something thats already a hot-button topic in the realm of health records. In addition to the stand-alone value of an intradermal information encoding and detection platform, this system may offer greater advantages when co-delivered with vaccines, they stated. hb````4a`g`bb@ !6(~_` 0. Sci Adv. 0000009528 00000 n The second annual student-industry conference was held in-person for the first time. Thats the ultimate goal, McHugh says: to always administer the medicine and the marker in tandem, so theres no risk of getting one without the other. ISSN 1548-7105 (online) 2017 Mar 1;50:522-533. doi: 10.1016/j.actbio.2016.12.028. What is luciferase and does it track people with the Covid vaccine? But you also want to mindful of the potential impact that science might have. In addition, we believe that familiarity with the function of these devices will lessen the learning curve for NIR imaging in a field setting..

Though the dots glow eventually fades, the nanoparticles stick around for good. Microneedles are embedded in a Band-Aid-like device that is placed on the skin; a skilled nurse or technician is not required. Rao says they decided to try using luminescent light to excite quantum dots. Some of this energy excites the quantum dot, resulting in the release of red light. Rao tried using this new Luc8 variant, and it worked. But Nagar acknowledges the possible concerns all such technology poses. With each passing day, it becomes . Self-illumination of Carbon Dots by Bioluminescence Resonance - Nature Biological response to PMMA-encapsulated quantum dots. 0000018201 00000 n below, credit the images to "MIT.". Along with the vaccine, a child would be injected with a bit of dye that is invisible to the naked eye but easily seen with a special cell-phone filter, combined with an app that shines near-infrared light onto the skin. 6.. Longitudinal imaging of NIR markings. Researchers at the U.S. Food and Drug Administration (FDA) have developed a simple, rapid, and sensitive test that identifies individuals who have made antibodies against respiratory syncytial virus (RSV), the most common cause of serious lower respiratory tract infection in infants and young children worldwide. Bioluminescence is widely used for in vivo imaging of nude mice. But adding more microneedles could make the designs more intricate, potentially conveying information about a vaccinations date, dosage, lot number and more. %%EOF bioengineers Robert Langer and Ana Jaklenec and their colleagues, uses a patch of tiny needles called microneedles to provide an effective vaccination without a teeth-clenching jab. 0000026038 00000 n The creation of a detachable microneedle system was achieved through the introduction of a disc section at the base of the microneedle shaft that was made from a water-soluble biopolymer, poly (ethylene glycol) (PEG); the PEG can be rapidly dissolved by body fluid, which allows for the microneedles to detach from the base patch enabling the While the researchers believe that the quantum dots are safe to use in this way because they are encapsulated in a biocompatible polymer, further safety studies are planned before progressing to tests in humans. Oxidation of coelenterazine by Luc8 conjugated to a quantum dot releases bioluminescence energy. The technology embeds immunization records into a childs skin. The FDA scientists showed that the LIPS assay could specifically detect anti-RSV-GA and -GB antibodies in mice that had been infected intranasally with RSV-A or -B strains. Before Writing for Scientific American, Karen Weintraub spotlights how MIT researchers have developed a new invisible ink that could be injected under a patients skin, leaving a record of their vaccination history. The name was first used by Raphal Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. The microneedles used in the reported study are made from a mixture of dissolvable sugar and a polymer called PVA, as well as the quantum-dot dye and, if appropriate, the vaccine. 4.. Smartphone modifications and near-infrared marking. In some areas in the developing world, it can be very challenging to do this, as there is a lack of data about who has been vaccinated and whether they need additional shots or not., But these problems arent unique to the developing world. Federal government websites often end in .gov or .mil. McHugh et al. Copyright 2023 Genetic Engineering & Biotechnology News. Its possible someday that this invisible approach could create new possibilities for data storage, biosensing, and vaccine applications that could improve how medical care is provided, particularly in the developing world, Langer says. 0000181405 00000 n 0000027694 00000 n Ideally, the formulations will remain detectable for at least several years, and perhaps longer, as most vaccinations are delivered during early childhood, McHugh says. 0000155272 00000 n 24, 339343 (2006). 0000155745 00000 n By using a microneedle form factor, this platform should easily assimilate into the future vaccination landscape because microneedles are currently in development for several vaccines and have shown advantages such as antigen dose sparing, improved antigen stability, and ease of (self-)administration compared to traditional soluble injections, the researchers commented. Luciferase is a real scientific term that refers to an enzyme capable of giving off light when it uses a substance called luciferin An example of this in action can be seen in the natural world with fireflies. The needles dissolve under the skin, leaving the encapsulated quantum dots. Cookie Settings, Courtesy of Kevin McHugh, Rice University, Figuring out how to keep better track of vaccination is incredibly important from a health systems and public health perspective, says Johns Hopkins University bioethicist, , who wasnt involved in the project. The availability of self-illuminating quantum dot conjugates will provide many new possibilities for in vivo imaging and detection, such as monitoring of in vivo cell trafficking, multiplex bioluminescence imaging and new quantum dot-based biosensors. The researchers hope to add more detailed information to the dots, such as the date of vaccination. MIT researchers have now developed a novel way to record a patient's vaccination history: storing the data in a pattern of dye, invisible to the naked eye, that is delivered under the skin at the same time as the vaccine. J Nanosci Nanotechnol. We tried firefly luciferase first, and it was very hard to do the conjugation, says Rao. 6.. Longitudinal imaging of NIR markings in rodent skin. The LIPS assay detects antibodies against G glycoprotein, (G protein), a molecule that occurs on the surface of the virus. This encapsulation allows the dye to remain in place, under the skin, after being injected. Their pattern can be read to identify the vaccine that was administered.
