What are the Applications of Nanotechnology in Cancer Treatment?
Nanotechnology has significant applications in cancer treatment, including:
1. Targeted Drug Delivery: Nanoparticles can be functionalized with ligands that specifically bind to cancer cell receptors, delivering cytotoxic drugs directly to the tumor. 2. Gene Therapy: Nanocarriers can deliver genetic material to cancer cells, potentially correcting genetic defects or sensitizing cells to chemotherapy. 3. Imaging and Diagnostics: Nanoparticles can enhance the contrast in imaging techniques like MRI and CT scans, aiding in early detection and monitoring of tumors. 4. Photothermal and Photodynamic Therapy: Nanoparticles can absorb light and convert it to heat, destroying cancer cells through hyperthermia or generating reactive oxygen species to induce cell death.
