engineers have developed a way to store medical information under the skin, using a quantum dot dye that is delivered, along with a vaccine, by a microneedle patch. No claim to original U.S. Government Works. The researchers found that vaccination with the microneedle patches was safe, with no serious related adverse events reported. Tattooed into its skin are the scars of old wounds; archived in the molecules of the immune system are the traces of past infections. The researchers plan to work with health care workers in developing nations in Africa to get input on the best way to implement this type of vaccination record keeping. "It's 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.

The site is secure. More information: The researchers believe the quantum dots are safe to use in this way because they are encapsulated in a biocompatible polymer, but they plan to do further safety studies before testing them in patients. 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. Medical Xpress is a part of Science X network. The dots are only about 4 nanometers in diameter, but they are encapsulated in biocompatible microparticles that form spheres about 20 microns in diameter. The researchers now plan to survey health care workers in developing nations in Africa to get input on the best way to implement this type of vaccination record keeping. ISSN 1548-7091 (print).

Over the course of two minutes, the nanoparticles diffuse from within the microneedles to a shallow layer of skin, where theyre deposited in simple patterns of dots, each smaller than your garden-variety freckle. The chemical is a 'near infrared bioluminescence enzyme' called Luciferase which makes the quantum dot vaccination readable through a special mobile device app. 0000155272 00000 n The microneedles don't leave scars and are less invasive than the regular needles its like putting on a Band-Aid,explains research scientist Ana Jaklenec. When people were still getting vaccinated for smallpox, which has since been eradicated worldwide, they got a visible scar on their arm from the shot that made it easy to identify who had been vaccinated and who had not, Jaklenec says. Synthesis of far-red- and near-infrared-emitting Cu-doped InP/ZnS (core/shell) quantum dots with controlled doping steps and their surface functionalization for bioconjugation.

Thinking Revelations the mark of the beast to buy, sell, trade This world is doomed, eventually, no matter what we do or dont do. [K.J. Many vaccines, such as the vaccine for measles, mumps, and rubella (MMR), require multiple doses spaced out at certain intervals; without accurate records, children may not receive all of the necessary doses. MIT researchers have developed a method of storing vaccination history underneath a patient'sskin, reports Elizabeth Cooney for STAT. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. With this aim, researchers at Massachusetts Institute of Technology have developed a microneedle patch containing a nanocrystal dye that creates near-infrared-emitting dots under the skin. More complexity, however, also introduces the possibility for more error. Like QR codes, these designs could be scanned and interpreted by smartphones, and someday allow health providers to archive and access patients past vaccinations without the muss and fuss of external records. The platform could feasibly provide clinicians with a more dependable way of keeping accurate medical records. In some areas in the developing world, it can be very challenging to do this, as there is a lack of data about who has been vaccinated and whether they need additional shots or not., But these problems arent unique to the developing world. 0000026668 00000 n 8600 Rockville Pike 22001 Loudoun County Pky, Ashburn, VA 20147 | LoopNet When the patch is applied to the skin, the microneedles, which are 1.5 mm long, partially dissolve, releasing their payload within about two minutes. To develop the assay, the FDA scientists genetically engineered RSV G proteins from both subgroups. 2023 Scientific American, a Division of Springer Nature America, Inc. eCollection 2021 Nov 9. Although quantum dots can emit light in the red and infrared regions of the spectrum that have good tissue penetration, they all require blue light for efficient excitation. This encapsulation allows the dye to remain in place, under the skin, after being injected. McHugh et al., Science Translational Medicine (2019), Smartphone images of the quantum dot markings in the skin of rodents at 0 weeks and 12 weeks after administration. 2023 Jan 5;4(1):1. doi: 10.1186/s43556-022-00102-2. Langer and Jaklenec are co-corresponding authors of the teams published paper in Science Translational Medicine, which is titled, Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination., Vaccines save an estimated 23million lives every year, but another 1.5 million vaccine-preventable deaths occur each year due to undervaccination, primarily in developing countries, the authors commented. Are we still hesitant? Thanks for reading Scientific American. You want to advance science. The researchers also tested the vaccination strategy in rats, using microneedle patches that delivered the quantum dots along with a polio vaccine. Along with them, the team eventually wants to inject sensors that could also potentially be used to track aspects of health such as insulin levels in diabetics, Jaklenec says. The grants expand funding for authors whose work brings diverse and chronically underrepresented perspectives to scholarship in the arts, humanities, and sciences.
