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. 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. Such patches are now being developed to deliver vaccines for measles, rubella, and other diseases, and the researchers showed that their dye could be easily incorporated into these patches. Many vaccines require multiple doses spaced out at certain intervals; without accurate records, people may not receive all of the necessary doses. Tests using the platform showed that QDs delivered to samples of human skin were still detectable after photobleaching that simulated five years of exposure sunlight, and they remained detectable for up to nine months when tested in rats.

The researchers encapsulated their quantum dots in microspheres made of PMMA, a material that improves biocompatibility. We tried firefly luciferase first, and it was very hard to do the conjugation, says Rao. Some participants developed local skin reactions to the patches, described as faint redness and mild itching that lasted two to three days. Several years ago, the MIT team set out to devise a method for recording vaccination information in a way that doesnt require a centralized database or other infrastructure. Fig. Their approach uses the Cowpea mosaic virus that infects legumes, engineering it to look like SARS-CoV-2, and weaving antigen peptides onto its surface, which will stimulate an immune response.. In addition, codelivery with inactivated poliovirus vaccine produced neutralizing antibody titers above the threshold considered protective. And when the team scanned the rats nine months later, they could still identify the symbols the microneedle patch had left. Cropped, but otherwise raw, smartphone images collected from a fixed distance showing the intradermal NIR signal from PMMA-encapsulated QDs delivered via microneedle patches on rats 0, 12, and 24 weeks after administration.
