Robust hydrogen-bonding interactions from deep eutectic solvent enabling high magneto-responsive performances

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

“…Other DES formed by ethylene glycol/choline chloride has been employed as the dispersion system of magnetic nanoparticles . Because of the strong hydrogen bonding interactions between the DES and the functional groups on the surfaces of the magnetic particles, the mechanical properties and sedimentation stability of the magnetorheological fluid (MRF) can be significantly improved . Inspired by the above research background, it is an interesting attempt to use DES as a dispersant, coagulation factor, and bacteriostatic agent to form magnetic fluid (DES-Fe 3 O 4 @TA) for effective and rapid hemostasis in complex wounds when used in combination with the polymer sponge rich in perforated channels.…”

“…In our previous study, choline chloride/malic acid (ChCl/Mal) was used as a cross-linking agent to prepare the electric response agarose hydrogel carrier for the treatment of skin inflammation, and it still shows excellent antibacterial activity . In recent years, the functional applications of DES have become more extensive, which can form magnetic fluid with magnetic particles and enrich the interaction system . The DES based magnetic fluid has shown the merits of simple structure, high reliability, and long service life .…”

“…In recent years, the functional applications of DES have become more extensive, which can form magnetic fluid with magnetic particles and enrich the interaction system . The DES based magnetic fluid has shown the merits of simple structure, high reliability, and long service life . For example, alcohol based DES can serve as the carrier of SiO 2 @Fe 3 O 4 .…”
