Abstract

Disclosed herein are nanofilm coatings for implantable medical devices comprising a diblock or triblock copolymer (PEO-PMMA or PMOXA-PDMS-PMOXA, respectively). Such nanofilms, may be used, for example, as amphiphilic supports for therapeutic agents. These materials are conducive towards the formation of active substrates for a suite of biological and medical applications.
