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. Researchers at the U.S. Food and Drug Administration (FDA) have developed a simple, rapid, and sensitive test that identifies individuals who have made antibodies against respiratory syncytial virus (RSV), the most common cause of serious lower respiratory tract infection in infants and young children worldwide.

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. The assay also found that serum from adolescents had antibodies against G proteins from both subtypes, suggesting that adolescents had been exposed to both RSV-A and RSV-B by that time in their lives. Note: 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.

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. But injectable nanoparticles that reveal private information about a patient could be ripe for misinterpretations and rumors, she says. Tests using human cadaver skin showed that the quantum-dot patterns could be detected by smartphone cameras after up to five years of simulated sun exposure.

Thats really the biggest challenge that we overcame in the project, Jaklenec says, adding that the team tested a number of off-the-shelf dyes that could be used in the body but could not find any that endured when exposed to sunlight. 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.

MIT researchers have developed a method of storing vaccination history underneath a patient'sskin, reports Elizabeth Cooney for STAT. Delivering the dye required the researchers to find something that was safe and would last long enough to be useful. In order to be protected against most pathogens, one needs multiple vaccinations, Jaklenec said. 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..

As the authors wrote, outbreaks of measles and mumps in the United States, Australia, and Italy have highlighted that poor immunization recordkeeping is not unique to developing nations. Without accurate vaccination records, they pointed out, healthcare professionals dont have all the data they need to make informed decisions about administering vaccines, and they may have to rely on parental recall. 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. 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. Potential patients could reject the procedure out of fear or mistrust, worrying, for instance, that authorities are using the patches to encrypt information onto individuals. 2013 Sep;13(9):6115-9. doi: 10.1166/jnn.2013.7634. 22001 Loudoun County Pkwy Ashburn VA 20147. doi: 10.1126/sciadv.abo8017. To create a microneedle platform that could be applied to the skin, rapidly dissolve, and leave behind particles that can later be imaged to determine vaccination status (Fig. The properties of these conjugates should make them suitable for use with animals larger than mice, and Rao says they are testing these conjugates for use for functional imaging in vivo. 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. QD-containing microparticles were then embedded in dissolvable microneedles and administered to rats with or without a vaccine.

It's a record that's invisible to the naked eye, written in quantum dots that emit near-infrared light readable by a modified smartphone. To create an on-patient, decentralized medical record, the researchers have now developed a new type of copper-based quantum dot, which emits light in the near-infrared spectrum. Biological response to PMMA-encapsulated quantum dots. The tattoo-esque technology, described today in the journal Science Translational Medicine, is still in the early stages of development, and hasnt yet been tested in humans. The platform could feasibly provide clinicians with a more dependable way of keeping accurate medical records. The development of the new assay is important because it could be a valuable tool for assessing the efficacy of RSV vaccines during clinical trials since it can help to identify individuals infected with RSV following a winter season. The name was first used by Raphal Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. bioengineers Robert Langer and Ana Jaklenec and their colleagues, uses a patch of tiny needles called microneedles to provide an effective vaccination without a teeth-clenching jab. 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.
