What Are Nanoparticles and How Are They Used in Medicine?
Nanoparticles are particles between 1 and 100 nanometers in size. They can be engineered to have specific properties and functions. In medicine, nanoparticles are used for:
Drug Delivery: Nanoparticles can deliver drugs directly to targeted cells, enhancing the efficacy and reducing side effects. For instance, liposomes and dendrimers are used to encase drugs for controlled release. Imaging: Nanoparticles can improve the resolution of imaging techniques like MRI and CT scans, aiding in early disease detection. Theranostics: These are multifunctional nanoparticles that combine therapy and diagnostics, enabling simultaneous imaging and treatment of diseases.
