On one hand we discuss the deposition of a biodegradable polymeric drug-release coating, based on well-established poly(L-lactide) (PLLA), on PEEK and on the other hand the modification of PEEK via sulfonation and its subsequent drug loading. Results are compared to pure PLLA-associated drug delivery systems and limits and perspectives are shown.展开更多
