Notes:
Hydrogel biomaterials were synthesized by radical copolymerization of N-vinylpyrrolidone (NVP) and 2-hydroxyethylmathacrylate (HEMA), with azobisisobutyronitrile (AIBN) asan initiator, reacting at 60~70℃ for 24 hours, which were designed as contact lens due to the goodchemical stability and high biocompatibility. The absorbency of bovine serum albumin (BSA) wasmeasured by the ultraviolet spectrophotometer. The influence of pH, initial protein concentration andionic strength were investigated in detail. The results showed that the absorption of protein onhydrogel biomaterials increased with the immersing time increasing, and was stable during 4 days.The absorption of protein on hydrogel increased with the equilibrium water content increasing. Theprotein absorption on hydrogels reduced the permeability of the oxygen of the biomaterials
