Design, synthesis, and characterisation of novel peptide bio-surfactants


Peptide bio-surfactants based on pancreatic polypeptide hormone will be engineered for use in the formulation of personal care products and pharmaceuticals. The peptides will be designed via computer-aided molecular modeling, and then synthesized using solid phase techniques. Their 3D structures will be studied using circular dichroism and nuclear magnetic resonance spectroscopy, and their interfacial properties investigated using a combination of small angle scattering, surface tensiometry and reflectivity measurements.
