The cover image illustrates conducting polymer films, grown in a patterned fashion, that are decorated with variety of biomolecules such as antibodies or proteins (represented by the flowers) to attract cells or other biomolecules (represented by the butterflies). This artistic image, created by SooHyun Park, represents the focus of this article on generating patterned films of conducting polymers with different geometries, surface chemistries, and biomolecules using the novel method of hydrogel-mediated electropolymerization towards the application in biosensing and cell/tissue engineering.
