Alternative Title

Adsorption of diblock polypeptides at solid liquid interfaces

Abstract

"Protein/peptide adsorption at solid/liquid interfaces is significantly affected by hydrophobic and electrostatic forces.l Dynamic light scattering (DLS) and isotherms were used for adsorption of diblock co-polypeptides with different properties on negatively charged poly(styrene) (PS) nanospheres. These peptides differ in their hydrophobicity and charge. Peptides with one hydrophilic and one non-polar (alanine) or with both hydorphilic blocks with opposite charges (glutamic acid and lysine) were chemically synthesized. Adsorption experiments were performed in aqueous solution, water/methanol and water/glycerol mixtures at different pHs to study both these effects. It was found that electrostatic interactions between the peptide and the surface are more dominant"--Abstract, leaf iv.
