A Biomimetic Strategy for the Fabrication of Micro- and Nanodiamond Composite Films

This investigation is motivated by increasing interest in diamond and composite films for applications biomedical electronic devices. A biomimetic strategy based on the use of commercial bile acids, such as ursodeoxycholic acid (UDCA) hyodeoxycholic (HDCA). Composite are developed using UDCA HDCA solubilizing agents poly(ethyl methacrylate) (PEMA) isopropanol dispersing micro- nanodiamonds. In this approach, traditional toxic solvents PEMA dissolution avoided. The ability to obtain high concentrations molecular mass disperse particles solutions a key factor development dip-coating method. dispersion mechanisms discussed. composition microstructure can be varied variation particle size concentration suspensions. obtained singular layers different compositions, multilayers similar composition, or alternating compositions. combine corrosion protection property biocompatibility with advanced functional properties diamonds.
