The Compressibility coefficient (CS1)-Surface pressure (π) curves of DOTAP monolayer on the subphase with different amount of BSA at pH = 3(a), 5(b) and 10(c) ([BSA] = 0(□); 5 × 10−9 M(○); 1 × 10−8 M(△); 5 × 10−8 M (▽); 8 × 10−8 M(◇)). (d): The variation of the maximum value of CS1 (CSmax1) with [BSA] at pH = 3, 5 and 10.
