The study of protein-surface interactions represents one of the most important topics in the field of biomaterials.It is believed that blood cells do not actually contact the biomaterial surface directly,but rather interact with the molecular structure of the adsorbed protein layer.Therefore,protein plays a key role in regulation and induction of cells.It provides ideas for biomaterials designing that exploring the molecular mechanism of controlling protein adsorption and regulating cell response.This paper reviews the research progress of the interactions of protein and surfaces,and prospects the future research direction.
