The impact of a number of parameters such as the chemistry of the oil used , the presence of co-surfactants , pH of assembly , functionalisation with charged moieties and physical or chemical crosslinking of proteins on interfacial mechanics and cell culture have been explored in the context of single protein solutions, from albumins and b-lactoglobulin to fibronectin. In particular, interfacial shear mechanics and viscoelasticity, rather than dilatational or indentation moduli, were found to correlate well with cell adhesion and proliferation .
