A principal challenge in wound healing is a lack of cell recruitment, cell infiltration, and vascularization, which occurs in the absence of temporal and spatial cues. We hypothesized that a scaffold that expands due to local changes in pH may

Polymeric dental adhesives require the formation of densely crosslinked network structures to best ensure mechanical strength and durability in clinical service. Monomeric precursors to these materials typically consist of mixtures of hydrophilic and hydrophobic components that potentially undergo phase separation
