A pH-sensitive, stimuli-responsive, superabsorbent, smart hydrogel from psyllium () for intelligent drug delivery.

Herein, we report a polysaccharide-based hydrogel isolated from psyllium husk (a well-known dietary fiber) and evaluated for its swelling properties in deionized water (DW) at different physiological pH values, , 1.2, 6.8 and 7.

A stimuli-responsive, superporous and non-toxic smart hydrogel from seeds of mugwort (): stimuli responsive swelling/deswelling, intelligent drug delivery and enhanced aceclofenac bioavailability.

seeds extrude hydrogel (AVH), which shows extraordinary swelling in water, at pH 6.8, and 7.4, which follows second-order kinetics.
