An interdisciplinary team of researchers at the UCLA Jonsson Comprehensive Cancer Center has developed a medicated patch that can deliver immune checkpoint inhibitors and cold plasma directly to tumors to help boost the immune response and kill cancer cells.
The thumb-sized patch has more than 200 hollow microneedles that can penetrate the skin and enter the tumor tissue. The cold plasma is delivered through the hollow structure, destroying cancer cells, which facilitates the release of tumor-specific antigens and boosts an immune response.
