In the meantime, to ensure continued support, we are displaying the site without styles %%EOF Thats the ultimate goal, McHugh says: to always administer the medicine and the marker in tandem, so theres no risk of getting one without the other. This ties the vaccine to the record itself, and ties the record to the person, McHugh says. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. 0000238728 00000 n McHugh and former visiting scientist Lihong Jing are the lead authors of the study, which appears today in Science Translational Medicine. 0000004430 00000 n https://doi.org/10.1038/nmeth0406-240a, DOI: https://doi.org/10.1038/nmeth0406-240a. The researchers encapsulated their quantum dots in microspheres made of PMMA, a material that improves biocompatibility. Figuring out how to keep better track of vaccination is incredibly important from a health systems and public health perspective, says Johns Hopkins University bioethicist Nancy Kass, who wasnt involved in the project. Quantum Dots Encode Vaccine History in the Skin - IEEE Spectrum Competing interests: A patent application entitled Microneedle tattoo patches and use thereof describing the approach presented here was filed by K.J.M., L.J., S.Y.S., H.S.N.J., A.J., and R.L.

Longitudinal in vivo imaging using a smartphone adapted to detect NIR light demonstrated that microneedle-delivered QD patterns remained bright and could be accurately identified using a machine learning algorithm 9 months after application. The dye has been shown to be safe in humans. Platform schematic and fluorescent probe. In parallel, microneedle geometry was optimized in silico and validated ex vivo using porcine and synthetic human skin. "In areas where paper vaccination cards are often lost or do not exist at all, and electronic databases are unheard of, this technology could enable the rapid and anonymous detection of patient vaccination history to ensure that every child is vaccinated," says Kevin McHugh, a former MIT postdoc who is now an assistant professor of bioengineering at Rice University. 0000279282 00000 n Since many of the current candidate vaccines contain or express only one or a few of the proteins found in the virus, antibody responses to non-vaccine RSV antigens can serve as a marker of exposure and infection in subjects given these vaccines. Though invisible to the naked eye, dots stamped onto pieces of pig and human skin lit up in clear patternsa circle, rectangle or crosswhen viewed through a smartphone fitted with an infrared filter, the team found. Before Note: The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. Concerns have been voiced about the ability of quantum dots to function as fluorescence resonance energy transfer acceptors for organic fluorophores.
