AUGUST 1ST, 2023 CONN HASTINGS DERMATOLOGY, MATERIALS, MEDICINE Researchers at the University of Hong Kong have developed a microneedle patch for the drug-free treatment of skin infections, such as acne. Acne is often treated using antibiotics, but these have limited effectiveness over the long term and can result in drug-resistant bacteria. In an effort to develop...
by Bob Yirka, Medical Xpress Blue-ringed octopus-inspired drug delivery patch. (A) Hydrogel microneedle (MN) suction cup drug delivery platform was developed by imitating the blue-ringed octopus’ predation process. This material achieves wet tissue surface adhesion and self-controlled multistage drug release. (B) Tissue adhesion of the hydrogel suction cups comes from negative pressure fixation and the...
SEPTEMBER 28TH, 2021 CONN HASTINGS MATERIALS, MEDICINE, SURGERY A team of scientists at Purdue University created a microneedle patch that can deliver oxygen and bactericidal agents to chronic wounds. The bacterial biofilms that form over non-healing wounds, such as foot ulcers, are a formidable barrier to successful treatment. Such wounds are typically hypoxic and the bacteria within...
AMERICAN CHEMICAL SOCIETY IMAGE: THIS MICRONEEDLE PATCH COULD SOMEDAY REPLACE A NEEDLE FOR DELIVERING COVID-19 VACCINES. CREDIT: ADAPTED FROM ACS NANO 2021, DOI: 10.1021/ACSNANO.1C03252 More than 2 billion people worldwide are fully vaccinated against COVID-19. However, many who live in resource-limited countries haven’t been able to get vaccines, partly because these areas lack temperature-controlled shipping...
By Nick Lavars August 16, 2021 Scientists in China have developed a new microneedle patch that has shown promise in treating hair loss, by taking aim at poor circulation and oxidative stressrob3000/Depositphotos Recent advances have put some interesting possibilities on the table when it comes to tackling hair loss, from topical solutions packed with stem...
by Tohoku University A pain-free, organic, and biodegradable drug delivery patch developed by researchers at Tohoku University for potential home health care. Credit: Matsuhiko Nishizawa A pain-free, organic and biodegradable drug delivery patch may be on the horizon for home health care patients soon. Researchers from Tohoku University have developed a biobattery-powered device capable of both delivering large molecule pharmaceuticals...
by Brandie Jefferson, Washington University in St. Louis Engineers at the McKelvey School of Engineering at Washington University in St. Louis have developed a microneedle patch that can be applied to the skin, capture a biomarker of interest from interstitial fluid and, thanks to its unprecedented sensitivity, allow clinicians to detect its presence. Credit: Sisi Cao...
Interstitial fluid, which resembles blood plasma and that is reachable near the surface of the skin, contains many biomarkers, including sodium, potassium, and proteins, associated with normal body function, as well as those related to certain diseases. Researchers from Sandia National Laboratories and University of New Mexico have working on a new microneedle patch that can draw large...
