What Are the Applications of Nanotechnology in the Bloodstream?
1. Drug Delivery: Nanoparticles can be designed to carry drugs and release them in a controlled manner. This improves the drug's therapeutic index and reduces toxicity. 2. Diagnostics: Nanosensors can detect biomarkers at very low concentrations, enabling early diagnosis of diseases such as cancer and cardiovascular conditions. 3. Imaging: Nanoparticles enhance the contrast in imaging techniques like MRI, CT scans, and PET scans, allowing for more precise visualization of tissues and organs. 4. Therapeutics: Nanoparticles can be used for photothermal therapy, where they absorb light and convert it to heat to kill cancer cells, or for gene therapy, where they deliver genetic material to specific cells.
