The surface is the interface of the nanoparticle with the environment and the ability to manipulate the surface of nanoparticles is essential for their use. Surface coating of nanoparticles refers to modification or functionalization of the surface properties of nanoparticles to enhance their imaging, drug delivery, stability, solubility, antireflection, anticorrosion, antifogging, UV resistant, prevent sulfurization, anti-microbial, self-cleaning, biological response, biocompatibility, safety, reactivity properties etc. The surface of a nanoparticle (the “core”) can be covered with a wide range of substances, which, in return, creates single- or multi-layers layer(s) (the “shell”) that can be either complete of incomplete. https://www.ste-mart.com/s...
