Polydopamine loaded fluorescent nanocellulose–agarose hydrogel: A pH-responsive drug delivery carrier for cancer therapy

Herein, PDA-Py–CNC–AG composite hydrogel was developed by agarose, polydopamine and pyrene fluorophore labeled nanocellulose through interpenetrating polymer network strategy, which exhibited both fluorescent characteristics and pH responsive properties. Moreover, the adhesion to cells and controlled release performance to drug of the developed hydrogel was enhanced by the incorporation of polydopamine. As compared with single network hydrogel,...
