A New Capillary-Channel Agarose Sponge Assembled with Deep Eutectic Solvent Based Magnetic Fluid for Rapid Hemostasis and Prevention of Bacterial Infection

A new composite sponge assisted by magnetic field-mediated guidance was developed for effective hemostasis. It was based on polydopamine capillary-channel agarose (PDA-CAGA) sponge as matrix; meanwhile, the combination of deep eutectic solvent (DES, choline chloride:glycerol = 1:1, M/M)-dispersed Fe
