An official website of the United States government, : But when that history gets translated into written medical records, things can quickly get dicey. ", Katherine J. Wu Creative Commons Attribution Non-Commercial No Derivatives license. After all, theres no point in advancing a technology that no ones going to use. In addition, codelivery with inactivated poliovirus vaccine produced neutralizing antibody titers above the threshold considered protective. by Geoffrey Grider May 3, 2020. In parallel, microneedle geometry was optimized in silico and validated ex vivo using porcine and synthetic human skin. 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. %PDF-1.4 % The technology embeds immunization records into a childs skin. Rao and colleagues thought there must be a way to solve this problem. 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.. If we dont have good data, its really difficult to eradicate disease, explains research scientist Ana Jaklenec. Tests using human cadaver skin showed that the quantum dot patterns could be detected by smartphone cameras after five years of simulated sun exposure. 0000027331 00000 n 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. 0000000016 00000 n https://doi.org/10.1038/nmeth0406-240a, DOI: https://doi.org/10.1038/nmeth0406-240a. RSV also affects many elderly individuals, especially those with underlying heart or lung disease, accounting for nearly as many hospitalizations as influenza. Researchers headed by a team at the Massachusetts Institute of Technology (MIT) have created a microneedle platform using fluorescent microparticles called quantum dots (QD), which can deliver vaccines and at the same time invisibly encode vaccination history directly in the skin. Note: With global reach of over 5 million monthly readers and featuring dedicated websites for hard sciences, technology, smedical research and health news, the neutralizing antibodies achieved were well above the threshold considered protective by the U.S. Centers for Disease Control and Prevention, the investigators stated. 0000025837 00000 n Bethesda, MD 20894, Web Policies But other experts caution that both technical and ethical hurdles might stymie its implementationincluding in places where new tools to combat the spread of disease are needed most. The scientists added special protein beads that bind the antibodies with the luciferase-tagged G proteins to the bottom of a plastic test well. Slider with three articles shown per slide. Even with multiple shots, he adds, the marks are small enough that your whole array of vaccines could fit within a couple inches.. MIT News | Massachusetts Institute of Technology, Storing medical information below the skins surface. 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. 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. 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. The method is still in an experimental stage and is not being used for any current vaccinations, including Covid-19 vaccines. stm.sciencemag.org/lookup/doi/ scitranslmed.aay7162, Journal information: 8600 Rockville Pike "In order to be protected against most pathogens, one needs multiple vaccinations," Jaklenec says. An important advantage of the new test, called a Luciferase Immunoprecipitation Systems (LIPS) assay, is that it is less complicated and easier to perform than other assays now available. Furthermore, Luc8 emits shorter-wavelength light than firefly luciferase, which overlaps better with the absorption spectrum of quantum dots and its activity is not dependent on the use of ATP. Before 3D printing of microneedle arrays for hair regeneration in a controllable region. More. 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. Epub 2019 Jul 11. McHugh and former visiting scientist Lihong Jing are the lead authors of the study, which appears today in Science Translational Medicine. Fig. 0000009528 00000 n Delivered by a microneedle patcha four-by-four grid of tiny, 1.5-millimeter-long spikes that hurt less than typical injectionstheyre made up of nanoparticles that are undetectable in visible light, glowing only when viewed in infrared. Its 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. 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. doi: 10.1126/sciadv.abo8017. This encapsulation allows the dye to remain in place, under the skin, after being injected. An accessory procedure like this, he says, could meet further resistance. stm.sciencemag.org/lookup/doi/ scitranslmed.aay7162, CDC: vaccination coverage generally high for those born in 2015-16. Karen Weintraub is a staff writer at USA Today, where she covers COVID, vaccine development and other health issues. 0000024334 00000 n 0000155745 00000 n Given the nature of these issues, the teams tattoos could end up widening the chasm between patients and health providers, both foreign and local, Kass says. 0000279443 00000 n The name was first used by Raphal Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. 2013 Sep;13(9):6115-9. doi: 10.1166/jnn.2013.7634. Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. McHugh stresses that if the microneedle patches someday make it out to the field, they wont be mandatory accompaniments to vaccination, and nanoparticle-free formulations would be available at the same sites. J Nanosci Nanotechnol. 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. These findings suggest that intradermal QDs can be used to reliably encode information and can be delivered with a vaccine, which may be particularly valuable in the developing world and open up new avenues for decentralized data storage and biosensing. Remove the word 'human' and it becomes 666. Biotechnol. How would one create the LUCIFERASE enzyme in the body? This 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, added Ana Jaklenec, a research scientist at MITs Koch Institute for Integrative Cancer Research. Making a technology usable doesnt guarantee itll be used, and there are plenty of reasons why patients might hesitate to sign on to such an unusual procedure. Verizon, 22001 Loudoun County Pkwy, Ashburn, VA, Electric Charging The LIPS assay detects antibodies against G glycoprotein, (G protein), a molecule that occurs on the surface of the virus. The dye has been shown to be safe in humans. Bioluminescence resonance energy transfer using luciferase - PubMed "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. below, credit the images to "MIT.". 0000009128 00000 n 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.

QDs with a copper indium selenide core and aluminum-doped zinc sulfide shell were tuned to emit in the NIR spectrum by controlling stoichiometry and shelling time. The research was funded by the Bill and Melinda Gates Foundation and the Koch Institute Support (core) Grant from the National Cancer Institute. Such a system of recording medical information must be extremely discreet and acceptable to the person whose health information is being recorded and his or her family, he says. 2023 Scientific American, a Division of Springer Nature America, Inc. 0000009589 00000 n Near-infrared quantum dot dye stores vaccination history under the skin And thats just on the practical side. 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. Smartphone images of the quantum dot markings in the skin of rodents at 0 weeks and 12 weeks after administration. 0000019101 00000 n Solving medicines record-keeping riddle, they argue, might just involve injecting patterns of invisible nanoparticles under the skin. HHS Vulnerability Disclosure, Help 0000006410 00000 n The next step, McHugh says, is to test a similar protocol in longer-lived animals like pigs, which share a lot of anatomical commonalities with humans, including the structure of their skin. 2022 Sep 30;8(39):eabo8017. The approach raises some privacy concerns, says Prausnitz, who helped invent microneedle technology and directs Georgia Techs Center for Drug Design, Development and Delivery. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered. 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. Optical images of microneedles and finite element analysis, Fig. 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. They are also working on expanding the amount of data that can be encoded in a single pattern, allowing them to include information such as the date of vaccine administration and the lot number of the vaccine batch. This encapsulation allows the dye to remain in place, under the skin, after being injected. Quantum-dot tattoos hold vaccination record | Rice News | News and In addition, the assay detected antibodies against either RSV-A or RSV-B in samples taken from infants who had contracted the diseasedepending on which subtype was present. Shaheed R, Acharya S, Shukla S, Kesarwani M, Acharya N. J Family Med Prim Care. 0000140471 00000 n Their pattern can be read to identify the vaccine that was administered. 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. The researchers hope to add more detailed information to the dots, such as the date of vaccination. Delivering the dye required the researchers to find something that was safe and would last long enough to be useful. 22001 Loudoun County Pky, Ashburn, VA 20147 | LoopNet Not Just Ventilators: Staff Trained to Run Them Are in Short Supply, Coronavirus Vaccines May Not Work for the Elderly--and This Lab Aims to Change That, "Fake News" Web Sites May Not Have a Major Effect on Elections. 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. ); pjayanti94@gmail.com (P.J. Quantum Dots Deliver Vaccines and Invisibly Encode Vaccination History If communication about the product isnt initiated early, I worry about the unintended consequences, she says.

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. Keeping track of vaccinations remains a major challenge in the developing world, and even in many developed countries, paperwork gets lost, and parents forget whether their child is up to date. Invisible Ink Could Reveal whether Kids Have Been Vaccinated Fig. Katherine J. Wu is a Boston-based science journalist and Story Collider senior producer whose work has appeared in National Geographic, Undark magazine, Popular Science and more. 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. In this study, Renilla luciferase-immobilized quantum dots-655 (QD-RLuc8) was used for bioluminescence resonance energy transfer (BRET)-mediated PDT to resolve these problems. Now, a team led by MIT scientists has come forward with a bold proposition that could write a legible vaccination history back into the bodys repertoire. 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. The emitted light is then detected by a specially modified smartphone ( Sci. 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. It remains to be seen if these microneedle patches fit the bill. Epub 2022 Sep 28.
