Interactions and applications of gold nanoparticles-protein

Gold nanoparticles and proteins can interact via physical adsorption,chemically covalent conjugation,affinity adsorption and so on.The surface plasma resonance and surface-enhanced Raman scattering of gold nanoparticles are usually used to investigate the interaction between nanoparticles and protein.Factors such as the size and surface chemistry of gold nanoparticles,property of proteins and environment of the solution can influence these interactions.Gold nanoparticles are widely applied in the fields of highly effective and low-cost detections for disease and environmental pollutants,and play an important role in the disease therapy via the special physic-chemical properties of gold nanoparticles and the interactions between nanoparticles and proteins.
