In a paper recently published in the journal Science Translational Medicine (via Futurism), the group of researchers, led by Kevin J. McHugh et al., says that it is exploring a novel approach for maintaining accurate vaccination records by testing the implantation of “near-infrared quantum dots,” or NIR QDs, into pig skin, rat skin, cadaver flesh, and synthetic human skin.
Researchers headed by a team at the Massachusetts Institute of Technology (MIT) have created a microneedle platform using fluorescent microparticles called quantum dots (QD), which can deliver vaccines and at the same time invisibly encode vaccination history directly in the skin.
Keeping track of vaccinations remains a major challenge in the developing world, and even in many developed countries, paperwork gets lost, and parents forget whether their child is up to date. Now a group of Massachusetts Institute of Technology researchers has developed a novel way to address this problem: embedding the record directly into the skin.

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.
For several years now, we’ve been hearing about “microneedle patches” that deliver medication less painfully and more safely than hypodermic needles. A new take on the technology may allow them to work even better, by copying the structure of venomous snakes’ fangs.
