Implantable Quantum Dot Microneedle Vaccination Delivery System Luciferase; an enzyme that catalyzes the oxidation of a luciferin, causing it to produce a visible glow. 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. This encapsulation allows the dye to remain in place, under the skin, after being injected. They are often used by scientists because they can help researchers monitor biological processes. To create an "on-patient," decentralized medical record, the researchers developed a new type of copper-based quantum dots, which emit light in the near-infrared spectrum. Multifunctional chitosan-magnetic graphene quantum dot nanocomposites 0000181366 00000 n Continue reading with a Scientific American subscription. Many vaccines require multiple doses spaced out at certain intervals; without accurate records, people may not receive all of the necessary doses. Carrying medical information on the bodyeven in a form thats invisible without a special filtercould invite stigma, discrimination or worse. Tests using the platform showed that QDs delivered to samples of human skin were still detectable after photobleaching that simulated five years of exposure sunlight, and they remained detectable for up to nine months when tested in rats. 0000010079 00000 n Massachusetts Institute of Technology. The approach raises some privacy concerns, says Prausnitz, who helped invent microneedle technology and directs Georgia Techs Center for Drug Design, Development and Delivery. 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. the neutralizing antibodies achieved were well above the threshold considered protective by the U.S. Centers for Disease Control and Prevention, the investigators stated. Storing medical information below the skin's surface - MIT News 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 dots are only about 4 nanometers in diameter, but they are encapsulated in biocompatible microparticles that form spheres about 20 microns in diameter. Science X Daily and the Weekly Email Newsletters are free features that allow you to receive your favourite sci-tech news updates. 0000028880 00000 n The formulation showing the greatest resistance to photobleaching after simulated sunlight exposure (5-year equivalence) through pigmented human skin was encapsulated in microparticles for use in vivo. 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.

McHugh el al., "Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination," Science Translational Medicine (2019). 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. When the patch is applied to the skin, the microneedles, which are 1.5 millimeters long, partially dissolve, releasing their payload within about two minutes. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. 0000007975 00000 n 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. With global reach of over 5 million monthly readers and featuring dedicated websites for hard sciences, technology, smedical research and health news, My hope is that this scientific work could someday have a significant impact in terms of enabling patients in the developing world to receive the correct vaccines when needed, explains Prof. Robert Langer. ); pjayanti94@gmail.com (P.J. Specialized dye, delivered along with a vaccine, could enable 'on-patient' storage of vaccination history. 0000024059 00000 n 0000125860 00000 n This ties the vaccine to the record itself, and ties the record to the person, McHugh says. Though the dots glow eventually fades, the nanoparticles stick around for good. Bioluminescence is widely used for in vivo imaging of nude mice. 0000024814 00000 n volume3,page 240 (2006)Cite this article. But adding more microneedles could make the designs more intricate, potentially conveying information about a vaccinations date, dosage, lot number and more. Even with multiple shots, he adds, the marks are small enough that your whole array of vaccines could fit within a couple inches.. Rao says they decided to try using luminescent light to excite quantum dots. 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. But the technology raise several ethical concerns that could stymie its progress.

However, we do not guarantee individual replies due to the high volume of messages. We tried firefly luciferase first, and it was very hard to do the conjugation, says Rao. The quantum dots are composed of nanocrystals, which emit near-infrared (NIR) light that can be detected by a specially equipped smartphone. One of the biggest issues, Lee says, involves privacy, something thats already a hot-button topic in the realm of health records. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. 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. Moreover, unlike some currently used tests, it readily differentiates immune responses against the two major subtypes of RSV, RSV-GA and RSV-GB. Lai PY, Huang CC, Chou TH, Ou KL, Chang JY. In addition, codelivery with inactivated poliovirus vaccine produced neutralizing antibody titers above the threshold considered protective. 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. RSV also affects many elderly individuals, especially those with underlying heart or lung disease, accounting for nearly as many hospitalizations as influenza. Nat Methods 3, 240 (2006). Many vaccines, such as the vaccine for measles, mumps, and rubella (MMR), require multiple doses spaced out at certain intervals; without accurate records, children may not receive all of the necessary doses. 1, ,A A - C), we first needed to identify a suitable candidate for long-term detection.We began by investigating the use of commercial fluorophores with emission . 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. Blue light, however, does not penetrate tissue well and also produces high background owing to excitation of endogenous fluorophores. But injectable nanoparticles that reveal private information about a patient could be ripe for misinterpretations and rumors, she says. When people were still getting vaccinated for smallpox, which has since been eradicated worldwide, they got a visible scar on their arm from the shot that made it easy to identify who had been vaccinated and who had not, Jaklenec says. "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. [KJ. Luciferase. Epub 2022 Aug 30. iScience. To create an on-patient, decentralized medical record, the researchers developed a new type of copper-based quantum dots, which emit light in the near-infrared spectrum. 0000109600 00000 n Private station.

Concerns have been voiced about the ability of quantum dots to function as fluorescence resonance energy transfer acceptors for organic fluorophores. The researchers also tested this vaccination strategy in rats, using microneedle patches that delivered the quantum dots along with a polio vaccine. Would you like email updates of new search results? But obviously, we didnt want to give people a scar, she says, noting that her team was looking for an identifier that would be invisible to the naked eye. stm.sciencemag.org/lookup/doi/ scitranslmed.aay7162, CDC: vaccination coverage generally high for those born in 2015-16. M.I.T. 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. 0000148497 00000 n 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. The consequences go far beyond a missed injection: Inconsistent recordkeeping is thought to play a large role in the 1.5 million deaths that occur due to undervaccination each year. Transl. The researchers designed their dye to be delivered by a microneedle patch rather than using a traditional syringe and needle.

The work was funded by the Bill & Melinda Gates Foundation and came about because of a direct request from Microsoft founder and philanthropist Bill Gates himself, who has been supporting efforts to wipe out diseases such as polio and measles across the world, Jaklenec says. Such a system of recording medical information must be extremely discreet and acceptable to the person whose health information is being recorded and his or her family, he says. Smartphone images of the quantum dot markings in the skin of rodents at 0 weeks and 12 weeks after administration.
