Colon‐Targeted Natural Polysaccharide‐Berberine Armored Hydrogel for the Treatment of Colitis

open access: yesAdvanced Healthcare Materials, EarlyView.
In this research, a novel hydrogel system targeting the colon is developed, incorporating Rhubarb polysaccharides and berberine‐loaded dendrimer. This hydrogel, forms through intermolecular hydrogen bonding and electrostatic interactions, accumulates in colonic tissues, effectively alleviating pathological immune hyperactivation while modulating gut ...

Advanced Oral Delivery Systems for Nutraceuticals

open access: yesAdvanced Healthcare Materials, EarlyView.
Emerging delivery technologies are explored to overcome barriers to oral nutraceutical absorption. Traditional carriers are compared with novel platforms including biodegradable polymers, MOFs, MPNs, and 3D printing. These systems enhance bioavailability, control release, and enable personalized nutrition.
