What are the Advantages of Using Nanoparticles in PDT?
1. Enhanced Delivery: Nanoparticles can encapsulate photosensitizers, improving their solubility and stability in biological environments. 2. Targeted Delivery: Surface modification of nanoparticles with targeting ligands ensures the selective accumulation of photosensitizers in the desired tissues or cells. 3. Controlled Release: Nanoparticles can be engineered to release the photosensitizer in response to specific stimuli, such as pH changes or enzymatic activity. 4. Multifunctionality: Nanoparticles can carry multiple therapeutic agents, enabling combination therapies that can enhance treatment efficacy.
