they are going to chip us like your dog or cat, be able to scan you to see if you have vaccines, but instead of a chip it will be needle holes scar to be seen under a light.
the corona virus vaccine willingness to take it will usher it in
incorporating the vaccine with the dye in the microneedle
social stigma to be pushed soon?
WILL YOU ACCEPT THIS MARK PROVING YOU ARE OF THE CLEAN and VACCINATED?

CAMBRIDGE, Mass., Jan. 7, 2020 โ Using fluorescent quantum dots, an MIT research team has created a way to administer vaccinations and record a patientโs vaccination history in the skin. The researchers developed a microneedle platform that can selectively deliver microparticles into the skin in various patterns, which remain invisible to the naked eye but can be detected in the infrared (IR) using a smartphone that has the IR filter removed. The microparticles contain quantum dots, which store the personโs vaccination history in a pattern of dye that is delivered under the skin at the same time as the vaccine.
The copper-based quantum dots emit light in the near-infrared (NIR) spectrum and are about 4 nm in diameter. They are encapsulated in the biocompatible microparticles, which are about 20 ฮผm in diameter. Encapsulation allows the dye to remain in place, under the skin, after being injected.
The microneedles used in the study were made from a mixture of dissolvable sugar and a synthetic, water-soluble polymer, as well as the dye and the vaccine. When the patch is applied to the skin, the microneedles, which are 1.5 mm long, partially dissolve, releasing their contents within about 2 min.
The patch can be customized to imprint different patterns that correspond to the type of vaccine being delivered. Tests using human cadaver skin showed that the quantum-dot patterns could be detected by modified smartphone cameras after up to five years of simulated sun exposure.
The researchers also tested their vaccination strategy in rats, using microneedle patches that delivered the quantum dots along with a polio vaccine. They found that the rats generated an immune response similar to the response of rats that had received a traditionally injected polio vaccine. Patterns were detected nine months after the intradermal delivery of microparticles in the rats. โThis 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,โ researcher Ana Jaklenec said.
Medical record-keeping is essential for proper vaccination coverage. However, maintaining or accessing records can be difficult, particularly in low-resource settings that lack centralized databases. The MIT researchers now plan to survey health care workers in developing nations to get input on the best way to implement this approach to vaccination record-keeping. They are also working on expanding the amount of data that can be encoded in a single pattern, to allow information such as the date of vaccine administration and the lot number of the vaccine batch to be included in the quantum-dot dye pattern. The researchers believe the quantum dots are safe to use in the skin because they are encapsulated in a biocompatible polymer, but they plan to do further safety studies before testing them in patients.
