Fabrication schematic and concept of tension-responsive system. (a) The PGC-C18 and PCL electrosprayed barrier coating (yellow) prevents release from the drug-loaded core (green). (b) Photographs of the native mesh with no dye, after dye-loading, and after subsequent coating. Tension is applied to the spray-coated system (bottom) longitudinally. (c) SEM image of device cross-section shows consistent morphology of microparticle coatings surrounding mesh core. (d) Advancing water contact angles for electrosprayed hydrophobic (top, PCL) and superhydrophobic (bottom, PCL:PGC-C18 1:1) coatings.
