Biocompatible near-infrared quantum dots delivered to the skin by Medical Xpress is a web-based medical and health news service that is part of the renowned Science X network. Specialized invisible dye, delivered along with a vaccine, could enable on-patient storage of vaccination history to save lives in regions where paper or digital records arent available. Advertising Notice the Science X network is one of the largest online communities for science-minded people. Working in the northern Indian state of Rajasthan, Nagar and his team have devised a necklace, resembling one worn locally, which compresses, encrypts and password protects medical information. 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. 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. Bioluminescence is widely used for in vivo imaging of nude mice. The site is secure. Directions. 2023 Scientific American, a Division of Springer Nature America, Inc. Moreover, unlike some currently used tests, it readily differentiates immune responses against the two major subtypes of RSV, RSV-GA and RSV-GB. 0000149965 00000 n 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.

Vaccines delivered with microneedles also may not need to be refrigerated, reducing both the cost and difficulty of delivery, Langer and Jaklenec say. Credit: K.J. 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. Please select the most appropriate category to facilitate processing of your request, Optional (only if you want to be contacted back). With similar concerns in mind, the researchers, led by bioengineers Robert Langer and Ana Jaklenec, are preparing to conduct surveys to assess whether the invisible tattoos would be accepted by locals in high-priority regions. Langer and Jaklenec are co-corresponding authors of the teams published paper in Science Translational Medicine, which is titled, Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination., Vaccines save an estimated 23million lives every year, but another 1.5 million vaccine-preventable deaths occur each year due to undervaccination, primarily in developing countries, the authors commented. The idea of administering tattoos en masse may not be well received, adds Kendall Hoyt, a biosecurity expert at Dartmouth Colleges Geisel School of Medicine who wasnt involved in the study. The microneedles don't leave scars and are less invasive than the regular needles its like putting on a Band-Aid,explains research scientist Ana Jaklenec. Its already difficult enough to get vaccines cleared to go into these countries, he says. You want to advance science. 0000025837 00000 n 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. Thermo-optical characterization of cadmium selenide/zinc sulfide (CdSe/ZnS) quantum dots embedded in biocompatible materials. Bill Gates is building something that we call the Human Implantable Quantum Dot Microneedle Vaccination Delivery System, and it needs an enzyme called Luciferase in order to make it work. Main Quantum. Now Jianghong Rao, Sanjiv Gambhir and colleagues from the Molecular Imaging and Bio-X Program for interdisciplinary research at Stanford describe the synthesis and the use of bioluminescent quantum dots for in vivo imaging.

In order to be protected against most pathogens, one needs multiple vaccinations, Jaklenec said. engineers have developed a way to store medical information under the skin, using a quantum dot dye that is delivered, along with a vaccine, by a microneedle patch. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). All Rights Reserved. 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. Here, we present an approach to encode medical history on a patient using the spatial distribution of biocompatible, near-infrared quantum dots (NIR QDs) in the dermis. The researchers designed their dye to be delivered by a microneedle patch rather than using a traditional syringe and needle. Ana Jaklenec, a research scientist at MIT's Koch Institute for Integrative Cancer Research, and Robert Langer, the David H. Koch Institute Professor at MIT, are the senior authors of the paper.
