Smartphone images of the quantum dot markings in the skin of rodents at 0 weeks and 12 weeks after administration. Moreover, unlike some currently used tests, it readily differentiates immune responses against the two major subtypes of RSV, RSV-GA and RSV-GB. 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. They found that those rats generated an immune response similar to the response of rats that received a traditional injected polio vaccine. Not Just Ventilators: Staff Trained to Run Them Are in Short Supply, Coronavirus Vaccines May Not Work for the Elderly--and This Lab Aims to Change That, "Fake News" Web Sites May Not Have a Major Effect on Elections. 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. Epub 2016 Dec 18. Its possible someday that this invisible approach could create new possibilities for data storage, biosensing, and vaccine applications that could improve how medical care is provided, particularly in the developing world, Langer says. Fig. 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. 1.. 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. The formulation showing the greatest resistance to photobleaching after simulated sunlight exposure (5-year equivalence) through pigmented human skin was encapsulated in microparticles for use in vivo.
