In this work, we characterize physical hydrogels based on poly(vinyl alcohol), PVA, as intelligent biointerfaces for surface-mediated drug delivery. Specifically, we assemble microstructured (μS) surface adhered hydrogels via noncryogenic gelation of PVA, namely polymer coagulation using sodium sulfate (Na(2)SO(4)). We
