Bill Gates is building something that we call the Human Implantable Quantum Dot Microneedle Vaccination Delivery System, and it needs an enzyme called Luciferase in order to make it work. Delivering the dye required the researchers to find something that was safe and would last long enough to be useful. When the patch is applied to the skin, the microneedles, which are 1.5 millimeters long, partially dissolve, releasing their payload within about two minutes. 0000030064 00000 n

By selectively loading microparticles into microneedles, the patches deliver a pattern in the skin that is invisible to the naked eye but can be scanned with a smartphone that has the infrared filter removed. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. Here, we present an approach to encode medical history on a patient using the spatial distribution of biocompatible, near-infrared quantum dots (NIR QDs) in the dermis.

Moreover, unlike some currently used tests, it readily differentiates immune responses against the two major subtypes of RSV, RSV-GA and RSV-GB. Add that onto the backlash that already comes part and parcel with vaccines on the whole, and the situation could compound hesitancy and misinformation, she says. The problem is compounded because many vaccines, such as the vaccine for measles, mumps, and rubella (MMR), require multiple doses spaced out at certain intervals.

Microneedle modeling, fabrication, and evaluation. Gambhir says that these probes will allow multiplexing so that multiple events can be monitored in the same living subject. Nanoscale. Credit: K.J. This approach is likely to be one of many trying to solve the problem of storing individuals medical information, says Ruchit Nagar, a fourth-year student at Harvard Medical School, who also was not involved in the new study. This encapsulation allows the dye to remain in place, under the skin, after being injected. And thats just on the practical side. The researchers showed that their new dye, which consists of nanocrystals called quantum dots, can remain for at least five years under the skin, where it emits near-infrared light that can be detected by a specially equipped smartphone. Several years ago, the MIT team set out to devise a method for recording vaccination information in a way that doesn't require a centralized database or other infrastructure. 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. More. Quantum dots have several advantageous characteristics that have made them the fluorophore of choice in many applications. 0000024814 00000 n
The patch is then removed, leaving behind a subtle mark that can still be imaged after being exposed to the equivalent of five years worth of sunlight, the teams experiments show. "Then there will be quantum dot micro-needles, a DIGITAL IDENTIFICATION MARK in the form of a dye under the skin, a sort of tattoo that can be detected with special light and/or scanners. But the teams experiments in rats suggest that these medical marks are both safe and long-lasting, and can be administered alongside vaccines without compromising efficacy. A pattern of 1.5-millimeter microneedles that contain vaccine and fluorescent quantum dots are applied as a patch. When the patch is applied to the skin, the microneedles, which are 1.5 millimeters long, partially dissolve, releasing their payload within about two minutes. The site is secure. MIT researchers have now developed a novel way to record a patients vaccination history: storing the data in a pattern of dye, invisible to the naked eye, that is delivered under the skin at the same time as the vaccine.

The work was funded by the Bill & Melinda Gates Foundation and came about because of a direct request from Microsoft founder and philanthropist Bill Gates himself, who has been supporting efforts to wipe out diseases such as polio and measles across the world, Jaklenec says. Note: Vaccines delivered with microneedles also may not need to be refrigerated, reducing both the cost and difficulty of delivery, Langer and Jaklenec say. Because these phones offer on-board processing power, camera applications, and inexpensive consumer-grade camera modules, we chose to adapt an existing smartphone to enable NIR imaging rather than build a completely new imaging system, they wrote. Discover world-changing science. More complexity, however, also introduces the possibility for more error.

This may result in the application of additional, unnecessary vaccine doses and therefore undue cost or, more problematically, missed opportunities to vaccinate, which leave the child at risk for contracting infectious diseases.. Oxidation of coelenterazine by Luc8 conjugated to a quantum dot releases bioluminescence energy. The research was funded by the Bill and Melinda Gates Foundation and the Koch Institute Support (core) Grant from the National Cancer Institute. 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. It remains to be seen if these microneedle patches fit the bill. Storage, access, and control of medical records is an important topic with many possible approaches, says Mark Prausnitz, chair of chemical and biomolecular engineering at Georgia Tech, who was not involved in the research. By selectively loading microparticles into microneedles, the patches deliver a pattern in the skin that is invisible to the naked eye but can be scanned with a smartphone that has the infrared filter removed. Imaging before and after the microneedle application of the on patient medical record on pig skin. Along with the vaccine, a child would be injected with a bit of dye that is invisible to the naked eye but easily seen with a special cell-phone filter, combined with an app that shines near-infrared light onto the 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. trailer
