New initiating systems based on silane (diphenylsilane (DPSi)) and/or amine (triethylamine (TEA)) and gold salt (Gold(III) chloride trihydrate (HAuCl4)) are proposed for an easy thermal cationic and/or radical polymerization of ɛcaprolactone (ɛ-CL) and trimethylolpropane triacrylate (TMPTA) at room temperature and under air. They ensure good to excellent polymerizations. Moreover, a direct inco...

BACKGROUND Chemical bonding of the drug onto surfaces by means of spacer molecules is accompanied with a reduction of the biological activity of the drug due to a constricted mobility since normally only short spacer molecule like aminopropyltrimethoxysilane (APMS) are used for drug coupling. This work aimed to study covalent attachment of heparin to titanium(oxide) surfaces by varying the leng...
