文摘

•: DPI and QCM-D are combined to study the adsorption behaviors of BSA and LYZ.
•: The adsorption of BSA is suppressed by elastic repulsion energy of PEG chains.
•: The adsorption of LYZ is balanced by entropy elasticity and hydrogen bonds.
•: The LYZ adsorbed mass has the lowest value at a critical graft region of PEG.
