Nanoparticles, such as gold nanoparticles, quantum dots, and carbon nanotubes, possess unique optical properties that can be exploited in phototherapy. These properties include:
- Enhanced Absorption: Nanoparticles can be designed to absorb specific wavelengths of light more efficiently than traditional materials. - Targeted Delivery: Nanoparticles can be functionalized with ligands or antibodies that specifically bind to diseased cells, ensuring that the light treatment is localized. - Controlled Release: Some nanoparticles can be engineered to release therapeutic agents in response to light, providing a combined therapy approach.
