Human serum albumin binding to silica nanoparticles - effect of protein fatty acid ligand

Ang, Joo; Henderson, Mark; Campbell, Richard A.; Lin, Jhih-Min; Yaron, Peter; Nelson, Andrew; White, John; Faunce, Thomas


Neutron reflectivity shows that fatted (F-HSA) and defatted (DF-HSA) versions of human serum albumin behave differently in their interaction with silica nanoparticles premixed in buffer solutions although these proteins have close to the same surface excess when the silica is absent. In both cases a silica containing film is quickly established at the air-water interface. This film is stable for F-HSA at all relative protein-silica concentrations measured. This behaviour has been verified for...[Show more]
