Cropped, but otherwise raw, smartphone images collected from a fixed distance showing the intradermal NIR signal from PMMA-encapsulated QDs delivered via microneedle patches on rats 0, 12, and 24 weeks after administration. The assay also found that serum from adolescents had antibodies against G proteins from both subtypes, suggesting that adolescents had been exposed to both RSV-A and RSV-B by that time in their lives. The researchers also tested the vaccination strategy in rats, using microneedle patches that delivered the quantum dots along with a polio vaccine. 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. 0000125059 00000 n 0000181366 00000 n ISSN 1548-7105 (online) It just has to be approached in the right way. To create a microneedle platform that could be applied to the skin, rapidly dissolve, and leave behind particles that can later be imaged to determine vaccination status (Fig. Synthesis of far-red- and near-infrared-emitting Cu-doped InP/ZnS (core/shell) quantum dots with controlled doping steps and their surface functionalization for bioconjugation. The research was funded by the Bill and Melinda Gates Foundation and the Koch Institute Support (core) Grant from the National Cancer Institute. Making a technology usable doesnt guarantee itll be used, and there are plenty of reasons why patients might hesitate to sign on to such an unusual procedure. The properties of these conjugates should make them suitable for use with animals larger than mice, and Rao says they are testing these conjugates for use for functional imaging in vivo. By conjugating luciferase protein to quantum dots, bio-luminescence resonance energy transfer Science Translational Medicine (2019)]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. Carrying medical information on the bodyeven in a form thats invisible without a special filtercould invite stigma, discrimination or worse. );susette.audet@fda.hhs.gov (S.A.); schwinn6@gmail.com (A.K.). The researchers showed that their new dye, which consists of nanocrystals called quantum dots, can remain for at least five years under the skin, where it emits near-infrared light that can be detected by a specially equipped smartphone. 0000002802 00000 n 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. 0000010133 00000 n Accurate medical recordkeeping is a major challenge in many low-resource settings where well-maintained centralized databases do not exist, contributing to 1.5 million vaccine-preventable deaths annually. This ties the vaccine to the record itself, and ties the record to the person, McHugh says. Yichi Su, Joel R. Walker, Michael Z.

No claim to original U.S. Government Works. In vivo imaging of NIR patterns in rodent skin. MIT researchers have now developed a novel way to record a patients 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. Rao tried using this new Luc8 variant, and it worked. Fig. ); sk4px@virginia.edu (S.K. Credit: K.J. A pattern of 1.5-millimeter microneedles that contain vaccine and fluorescent quantum dots are applied as a patch. The researchers designed their dye to be delivered by a microneedle patch rather than a traditional syringe and needle. The name was first used by Raphal Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. The team ended up using a technology called quantum dots, tiny semiconducting crystals that reflect light and were originally developed to label cells during research. 0000151738 00000 n The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely. Credit: K.J. 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.
