Development and In Vitro Characterization of Hyaluronic Acid-Based Coatings for Implant-Associated Local Drug Delivery Systems
Figure 4
Representative ESEM micrographs of HA base layer coupled to (a) unmodified, (b) APTES-modified, and (c) GPTMS-modified PA12 surfaces. For better visualization of the coating, the coating boundary was put into focus. Attachment of HA to unmodified surfaces was performed according to conditions for GPTMS-modified surfaces.
