"Invisible Ink Could Reveal whether Kids Have Been Vaccinated
The technology embeds immunization records into a child’s skin.
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. “If we don’t have good data, it’s really difficult to eradicate disease,” she says."

"Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination
Vaccines prevent disease and save lives; however, lack of standardized immunization recordkeeping makes it challenging to track vaccine coverage across the world. McHugh et al. developed dissolvable microneedles that deliver patterns of near-infrared light-emitting microparticles to the skin. Particle patterns are invisible to the eye but can be imaged using modified smartphones. By codelivering a vaccine, the pattern of particles in the skin could serve as an on-person vaccination record. Patterns were detected 9 months after intradermal delivery of microparticles in rats, and codelivery of inactivated poliovirus led to protective antibody production. Discrete microneedle-delivered microparticle patterns in porcine and pigmented human skin were identifiable using semiautomated machine learning. These results demonstrate proof of concept for intradermal on-person vaccination recordkeeping."
