Nanotechnology achieves reduced toxicity through several strategies:
1. Surface Modification: By altering the surface properties of nanoparticles, such as coating with biocompatible materials, the interaction with biological systems can be minimized. 2. Biodegradable Materials: Utilizing materials that can be naturally broken down by the body reduces long-term toxicity. 3. Targeted Delivery Systems: Ensuring that nanoparticles specifically target diseased cells, such as in cancer therapy, minimizes exposure to healthy cells. 4. Green Synthesis Methods: Employing environmentally friendly synthesis methods reduces the generation of toxic by-products.
