Adsorption of Milk Proteins (b-Casein and b-Lactoglobulin) and BSA onto Hydrophobic Surfaces

International audienceHere, we study films of proteins over planar surfaces and protein-coated microspheres obtained from the adsorption of three different proteins (b-casein, b-lactoglobulin and bovine serum albumin (BSA)). The investigation of protein films in planar surfaces is performed by combining quartz crystal microbalance (QCM) and atomic force microscopy (AFM) measurementswith all-atomic molecular dynamics (MD) simulations. We found that BSA and b-lactoglobulin form compact monolayers, almost without interstices between the proteins. However, b-casein adsorbs forming multilayers...
