Researchers are exploring the use of microneedle patches to deliver PROTACs, a type of anti-cancer therapy. This approach is part of a broader effort to develop smart delivery systems and precision oncology treatments, which may also involve technologies like CRISPR-Cas9 and wearable bioelectronics. The goal of these advancements is to create more effective and targeted cancer therapies, with some studies suggesting the potential to destroy cancer cells without harming healthy tissue.
