Photodynamic therapy (PDT) is a non-invasive treatment that uses light to activate special medicines, called photosensitizers, to kill cells or destroy bacterial biofilms. This therapy has been widely used to treat cancer due to its precision and minimal invasion. Researchers are now exploring the use of nanomaterials to improve PDT. This includes developing new photosensitizers that can be activated by deep-red or near-infrared light, which can penetrate deeper into tissues. Additionally, scientists are working on creating hypoxia-resistant PDT, which can target areas with low oxygen levels, and antibacterial strategies to combat infections. The goal is to improve the effectiveness and delivery of PDT, making it a more powerful tool in the fight against cancer and other diseases. By advancing the field of nanomaterials for PDT, researchers aim to create new and innovative treatments that can improve patient outcomes.
