Surface Functionalization of AgNPs

The surface fabrication of AgNPs with different functionalities provides supplementary appendages for extended applications. These functionalities provide base for further anchoring, conjugation, or interacting with biomolecules, polymers, and synthetic chemical molecules deliberated at their biological target. The surface functionalities mask the engineered surface and surface properties of AgNPs and prevent them from modifications in situ. Moreover, the surface functionalized AgNPs with functional head groups enables their further conjugation to the nucleic acids, aptamers, peptides, and lipopolysaccharides that provide excellent applications in molecular medicine. This chapter presents the surface functionalization of AgNPs with natural molecules such as polysaccharides, amino acids, nucleic acids, peptides and their applications.
