Adsorption of Polylysine, Poly(glutamic) acid and their Block Copolymers on Polystyrene and on Carbon Nanotubes

A better understanding of protein behavior at solid-liquid interfaces is important to improve our knowledge of various natural and synthetic processes. A few examples where protein adsorption at a solid-liquid interface may play an important role are found in: blood coagulation, artificial kidney failure, biomedical microdevices, self-assembling microelectromechanical systems (MEMS), protein based microarrays, design and fabrication of biosensors/ biomaterials, filtration systems in bioseparation processes, etc. The structure of adsorbed proteins, its dependence on sorbent and solution properties, and the contribution of protein structural rearrangements to the driving force for adsorption are the most poorly understood aspects of the protein adsorption processes
