Smart sensing fabrics are becoming increasingly attractive in the emerging wearable areas of medical and military so far. Here, for first time, we present a smart humidity fabric (SHSF) based on moisture-sensitive polyacrylamide hydrogel respiratory monitoring non-contact sensing. Fabricated by situ cross-linking precursors fibers fabric, flexible SHSF shows excellent sensitivity, outstanding f...
Stimuli-sensitive hydrogels (or smart hydrogels) are hydrogels that swell or shrink in response to small changes in environmental conditions in which they are placed. While the extent of swelling or shrinking may be large, the kinetics of such changes is slow, since the diffusion of water into and out of the hydrogel is a slow process. To obtain fast responses, we have prepared superporous hydr...
A hydrogel exhibits a real-time depth-controllable swimming motion via light-mediated modulation of local density to mimic the volume changes found in the bladders of fish. Moreover, other motions, e.g., rolling, somersaulting, and bipedal-like walking, can also be realized by designing or combining gel shapes, and the location of light.
The common techniques to improve hydrogel's mechanical properties include increasing crosslinking density and forming crosslinked double-network hydrogel, which may cause some hydrogels lose their smart functionalities. Inspired by entanglement-induced strengthening, a simple approach introducing hydroxypropyl cellulose (HPC) fibers entangled with different hydrogel matrix systems are reported....
Fluorescent hydrogels have recently become one of the most prominent materials for smart confidential information protection. But it is still quite challenging to develop a 3D anticounterfeiting platform with on-demand decryption and transmission capacities, which are great importance achieve high-level data protection security. Herein, robust aggregation-induced emissive polymeric thermo-trigg...
The repair of peripheral nerve injuries is still one of the most challenging tasks and concerns in neurosurgery. Effect of methylprednisolone-laden hydrogel loaded into a chitosan conduit on the functional recovery of peripheral nerve using a rat sciatic nerve regeneration model was assessed. A 10-mm sciatic nerve defect was bridged using a chitosan conduit (CHIT/CGP-Hydrogel) filled with CGP-h...
Wharton’s jelly mesenchymal stem cells (HWJMSCs) hold promise for myocardial regeneration, but optimal treatment regimen (preferably with a growth factor) is required to maximize functional benefits. The aim of this study was to explore the cardioprotective and angiogenesis effects of HWJMSCs combined with insulin-like growth factor-1 (IGF-1) in the treatment of acute myocardial infarction. Th...
