Surface modification of materials has many advantages such as keeping the original mechanical quality and improving the surface biocompatibility. This technique has wide ranging applications in the development of biomaterials. Surfaces modified by a thin film of surfactants can control the properties of material surfaces more precisely than traditional coating or plasma coating. The development of this technique is expected to have large ramifications for minimizing bioelectrodes and discovering bio/blood compatibility materials.
Due to their good biocompatibility, natural surfactants have been commonly applied in the systems of drug delivery, surface modification, lung surfactants replacement therapy, and cell membrane modeling. The performance of these natural surfactants mainly determined by their dynamic interfacial properties. Thus, it is important to have a better understanding on the dispersion, adsorption, phase transition, and stability behavior of these surfactants.
Transport phenomena, including momentum, mass and heat transfer, is an essential issue in characterizing a physiological system and designing an artificial medical device. It is our goal to build up theoretical models in helping artificial organ design. "The permeation properties of a reconstructed collagen matrix" and "The energy effect on the damage of UHMWPE used in a knee arthroplasty" are two related studies in our lab.
