The binding properties of nanoparticles in contact with water depend on various factors such as their shape, size, surface characteristics, and inner structure. Moreover, physicochemical properties like surface charge, surface roughness, hydrophobicity, and crystal structure can also influence the interaction between nanoparticles and water. For example, surface charge plays a critical role in determining the interaction between nanoparticles and water, as it influences the colloidal behavior and aggregation state of the particles. Surface coatings and functionalization can also affect the nanoparticle-water interaction by altering the physicochemical properties of the nanoparticles. Thus, it is not accurate to say that each type of nanoparticle has specific binding properties when in contact with water, as these properties are influenced by various factors and can differ significantly even within the same type of nanoparticle.
