Microneedle patches full of active ingredients designed to help manage spots and breakouts, reducing the time it takes for these pesky blemishes to disappear. To create an “on-patient,” decentralized medical record, the researchers developed a new type of copper-based quantum dots, which emit light in the near-infrared spectrum. The dots are only about 4 nanometers in diameter, but they are encapsulated in biocompatible microparticles that form spheres about 20 microns in diameter. This encapsulation allows the dye to remain in place, under the skin, after being injected.

It is hoped that the patches, which are described in the journal Biomaterials Advances, will be ready for use within the next five to 10 years. The scientist says they would be happy to manufacture the microneedle patches for use by researchers on vaccines and treatments. At present, researchers are testing the utility of arrays in delivering chemotherapy to treat skin cancer, but they could easily be used this way as well. The approach directly converts the greenhouse gas into formate, a solid fuel that can be stored indefinitely and could be used to heat homes or power industries.

Needle phobia can affect both adults and children, and sometimes can lead to fainting. The benefit of microneedle arrays is that they reduce anxiety that patients have when confronted with a hypodermic needle. In addition to improving psychological and emotional comfort, microneedles have been shown to be substantially less painful than conventional injections. [9] Some studies recorded children's views on blood sampling with microneedles and found patients were more willing when prompted with a less painful procedure than traditional sampling with needles. Microneedles are beneficial to physicians as well, since they produce less hazardous waste than needles and are generally easier to use. Microneedles are also less expensive than needles as they require less material and the material used is cheaper than the materials in hypodermic needles. She said: “You can experience gastrointestinal side-effects; there is a delay between taking the medication and the drug getting to where it’s needed in the body; doses need to be higher because a lot of the formulation is broken down in the gut, and if the patient is taking antibiotics, this can also contribute to antimicrobial drug-resistance.'

Microneedle patches can be used directly over a spot, cluster of spots or even on an area where you feel a spot is about to appear. Vice Reversa Microneedle Pimple Patches contain salicylic acid and green tea extract* to cleanse the skin of dirt and bacteria and reduce redness and swelling. They also contain totarol to help protect the skin from UV damage and environmental toxins. Each patch holds an impressive 500 microscopic dissolving needles.Alleman, M. M. et al.

Prausnitz says the microneedle patch is an offshoot of the computer chip industry. Chipmakers got really good at making tiny structures out of silicon. Two or three doses of standalone IPV or combined IRV-IPV in the first-generation dMNP at full or half dose induced protective titers (≥1:8) of NA to the corresponding PV types 1, 2, and 3 in rats (Fig. 5d–f). The differences in antibody titer between post-vaccine doses 2 and 3 of full dose standalone IPV and full IRV-IPV were not statistically significant. Similarly, the differences in antibody titer between post-vaccine doses 2 and 3 of full-dose IPV, full-dose IRV-IPV, and half-dose IPV or half-dose IRV-IPV were not statistically significant. Of the three IPV types, IPV 2 was the most immunogenic and induced high geometric mean titers (GMTs) to PV type 2 even with a single dose. Corbett, H. J., Fernando, G. J., Chen, X., Frazer, I.

To fabricate full dose IRV dMNP, casting solutions had a concentration of 0.625 mg/ml IRV, 2% w/v sucrose (VWR, OH, USA) and 0.4% w/v sodium methylcellulose. IPV casting solutions had a concentration of 5.8, 1.1, and 5.2 DU/μl of types 1, 2, and 3, respectively, 1.5% w/v maltodextrin (Sigma-Aldrich, MO, USA) and 0.5 % w/v xylitol. Full-dose combination patches were prepared to deliver 5 μg IRV and 40, 8, and 32 DU of IPV types 1, 2, and 3, respectively. Solutions for manufacturing the quarter dose dMNP contained lower vaccine doses while keeping the excipient concentrations constant. After deposition of the polymer matrix solution, all MN arrays were dried at 35 °C overnight. Stability studies

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,” Jaklenec says. They are also more affordable than other commercially available microneedle patches, as they are produced from 3D printed moulds. Moulds produced this way are easy to customise, which keeps the costs down. Painless delivery All immunogenicity results were analyzed by Prism software version 7 (GraphPad, CA, USA). Comparisons among individual samples were done using an unpaired t test. Comparisons among multiple groups were done using a two-way ANOVA. p< 0.05 was considered significant.
