Early smart materials were typically amorphous polymers, hydrogels, or liquid crystalline systems with randomly distributed responsive groups, which limited response speed, energy efficiency, and the ...

Hydrogels, also known as soft matter in the medical world, are leading materials for biomedical applications such as drug delivery and stem cell therapy. But traditional hydrogels, used in products ...

A 4D printed microrobot integrates magnetic actuation, optical pH readout, and pH-triggered morphing to link navigation, measurement, and on-cue drug release. (Nanowerk Spotlight) Tiny changes in body ...

Nanoparticles enhance drug solubility, stability, and bioavailability, improving therapeutic outcomes for GI conditions like IBD through targeted delivery mechanisms. Hydrogel-based systems offer ...

Bioengineers and physicians team up to develop a better delivery system for getting anti-inflammatory therapies to the sites where they are needed most. Arthritis flares -- the unpredictable and often ...

(Nanowerk Spotlight) Hydrogels are crosslinked polymer networks that can absorb huge volumes of water. In recent years, significant progress has been made with so-called "stimuli-responsive" hydrogels ...

A recent study in Nature Communications introduces a hydrogel (OSPPB) designed to mitigate osteoarthritis (OA) by scavenging extracellular RNA and releasing bevacizumab to inhibit neurovascularization ...
