The chemical environment significantly impacts the behavior of nanomaterials. Factors such as pH, ionic strength, and the presence of specific chemical species can influence the surface chemistry and interactions of nanomaterials. For instance, a change in pH can alter the surface charge of nanoparticles, affecting their aggregation and dispersion. Similarly, the presence of certain ions can lead to the formation of complexes on the nanoparticle surface, modifying their properties.
