What are nanoparticles and how are they used in cancer diagnostics?
Nanoparticles are tiny particles that range in size from 1 to 100 nanometers. They can be engineered to bind specifically to cancer cells and can be imaged using various techniques like MRI, CT scans, and fluorescence imaging. Nanoparticles can also carry contrast agents, making it easier to distinguish cancerous tissues from healthy ones.
