Amino groups are often used to functionalize the surface of nanoparticles, allowing them to interact with biological molecules or other chemical species. This functionalization can improve the dispersion of nanoparticles in various solvents, enhance their biocompatibility, and enable specific binding to target molecules. For example, amino-functionalized nanoparticles can be used in drug delivery systems to target specific cells or tissues, increasing the efficacy of the treatment while minimizing side effects.
