New bifunctional composite bioceramic hydrogel shows promise for treating skin cancer

By Lisa McDonald / June 1, 2021

Treatment of melanoma, the deadliest form of skin cancer, often involves removing the affected tissue or organ, which leaves wounds that are difficult to heal. Researchers in China, Turkey, and Australia developed a new bifunctional composite bioceramic hydrogel for treating melanoma via a minimally invasive technique called photothermal treatment.
