New stretchable skin patch targets melanoma with graphene and copper
Scientists have created a stretchable, heat-activated skin patch designed to treat melanoma. The device uses graphene and copper to target cancer cells while leaving healthy tissue unharmed. Early tests suggest it could offer a simple, reusable way for patients to manage treatment outside hospitals. The patch combines laser-induced graphene with copper(II) oxide nanoparticles, all embedded in a flexible silicone polymer. When gently heated, it releases copper ions that attack melanoma cells through oxidative stress and DNA damage. Lab tests showed the treatment triggered significant cell death and reduced cancer cell movement.
In animal studies, the patch shrank tumours by 97% without spreading copper ions through the body. The graphene layer ensures durability and even heat distribution, allowing precise control over ion release. Researchers believe this design could eventually be adjusted for other skin cancers or infections.
Future work will focus on refining how the patch releases ions over time. The team also plans longer safety and effectiveness trials, though human testing has not yet begun. As of April 2026, only preclinical and lab-based research exists for this technology. The patch's reusable design and targeted approach could change how melanoma is treated in outpatient settings. If successful in further testing, it may also be paired with wearable tech for remote health tracking. For now, the focus remains on preparing for eventual clinical trials in people.
