How Does Nanotechnology Enhance Photodynamic Therapy?
Nanotechnology plays a critical role in enhancing the efficacy and precision of PDT. By leveraging nanoparticles, we can improve the delivery, targeting, and activation of photosensitizers. Nanoparticles can be engineered to encapsulate photosensitizers, protecting them from degradation and ensuring they reach the target cells in higher concentrations. Additionally, nanoparticles can be functionalized with targeting ligands that bind specifically to cancer cells, enhancing the selectivity of the treatment.
