In this work, we provided a photocurable bioink composed of modified epsilon-poly-l-lysine (EPL-MA) for digital light processing (DLP). The EPL-MA was facilely synthesized by grafting with the glycidyl methacrylate (GMA) via a nucleophilic amination ring-opening reaction and forming linkages betw...
EPL serves not only as a major matrix material for the microneedle tips, but also as a broad-spectrum antibacterial agent that facilitates the intracellular accumulation of the antibiotic doxycycline (DOX) by increasing bacterial cell membrane permeability. Furthermore, the formation of physically ...
