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. 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. It doesn't require any link to a database and it. 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. 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.. 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. Human Implantable Quantum Dot Micro needle vaccination.
