Researchers employ various strategies to achieve low toxicity in nanotechnology:
Surface Modification: By altering the surface properties of nanomaterials, such as coating them with biocompatible polymers, researchers can reduce their toxicity. Size and Shape Control: The size and shape of nanoparticles influence their interaction with biological systems. Optimizing these parameters can help in reducing toxicity. Material Selection: Choosing inherently biocompatible materials, such as gold nanoparticles or silica-based nanoparticles, can lower toxicity levels. Functionalization: Attaching specific functional groups to the nanomaterial's surface can enhance biocompatibility and reduce undesired interactions.
