Now, researchers publishing in ACS Nano report they have developed a potential noninvasive treatment for melanoma in the form of a stretchy, heat-activated patch similar to a bandage. When activated, the patch releases copper ions that kill the underlying cancer cells and prevent them from spreading. In tests with mice, the researchers say the patch reduced melanoma lesions without damaging surrounding tissue. https://medicalxpress.com/news/2026-04-skin-patch-melanoma-cells-surgery.html Wed, 01 Apr 2026 12:20:05 EDT news694262881 Millions of people in the United States have chronic wounds, including those living with diabetes, patients recovering from burns, post-surgical patients and other people with injuries. For clinicians, early detection of infection, inflammation or other recovery setbacks can be challenging to detect, primarily because patients may be self-reporting or awaiting lab results. This can result in a worsening infection, long-term damage and, in some cases, amputation. https://medicalxpress.com/news/2026-03-smart-bandage-tracks-wound-status.html Sun, 29 Mar 2026 10:00:18 EDT news693752690 Researchers from the University of California San Diego Sanford Stem Cell Institute have developed a novel method to stimulate and mature human brain organoids using graphene, a one-atom-thick sheet of carbon. https://medicalxpress.com/news/2025-08-graphene-technology-matures-brain-organoids.html Wed, 20 Aug 2025 05:00:02 EDT news674818081 After an amputation or a severe nerve injury, patients lose to a greater or lesser extent the ability to move and feel a lost limb, which limits their autonomy in activities of daily living. Currently, the only strategy that allows recovery of the lost functions consists of neuroprostheses: electrodes capable of stimulating the nerves to induce specific sensations, and of recording motor signals that, once decoded, can be sent to a bionic prosthesis. https://medicalxpress.com/news/2024-07-material-derived-graphene-neuroprostheses.html Wed, 10 Jul 2024 14:30:11 EDT news639840607 Researchers led by Northwestern University and the University of Texas at Austin (UT) have developed the first cardiac implant made from graphene, a two-dimensional super material with ultra-strong, lightweight and conductive properties. https://medicalxpress.com/news/2023-04-graphene-tattoo-cardiac-arrhythmia.html Mon, 17 Apr 2023 16:41:20 EDT news600968473 Computer and Robot Assisted Surgery is an area receiving broad attention worldwide because of its strong potential to advance new levels of healthcare. In Europe, the robotics and cognitive science communities have been independently pursuing research in this field, making significant, but fragmented contributions. Furthermore, strong surgical instrument manufacturers are now present in Europe. https://medicalxpress.com/news/2020-06-artificial-skin-graphene-revolutionize-robotic.html Mon, 15 Jun 2020 09:23:50 EDT news511431827 The body of knowledge about the human brain is growing exponentially, but questions big and small remain unanswered. Researchers have been using electrode arrays to map electrical activity in different brain regions to understand brain function. Until now, however, these arrays have only been able to detect activity over a certain frequency threshold. A new technology developed in Barcelona overcomes this technical limitation, unlocking the wealth of information found below 0.1 Hz and paving the way for future brain-computer interfaces. https://medicalxpress.com/news/2019-01-graphene-based-implant-technical-limitation-brain.html Thu, 03 Jan 2019 06:56:00 EST news465720949 Researchers looking for ways to regenerate nerves can have a hard time obtaining key tools of their trade. https://medicalxpress.com/news/2017-04-graphene-electricity-stem-cells-nerve.html Mon, 10 Apr 2017 16:00:22 EDT news411058812
