Real‐Time Stress Visualization of Hydrogels Enabled by Supramolecularly Switched Stretch‐Induced Phase Separation

Advanced Science, EarlyView.
Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Chemical‐Biological Fixation for Enhanced Bone Augmentation in Guided Bone Regeneration

Advanced Science, EarlyView.
M2N2ACa is an innovative injectable thermoresponsive barrier membrane adhesive to achieve reliable bone graft fixation. It provides strong wet adhesion and promotes the bio‐stabilization mediated by coagulation through controlled calcium release. This dual‐fixation strategy combines external chemical fixation and internal biological fixation via clot ...

Sustained Release of Naltrexone from Poly(N‐Isopropylacrylamide) Microgels [PDF]

Journal of Pharmaceutical Sciences, 2014
The release of the opioid antagonist naltrexone from neutral poly(N-isopropylacrylamide) (PNIPAAM) microgels and negatively charged PNIPAAM microgels containing acrylic acid groups (PNIPAAM-co-PAA) has been studied at various microgel and drug concentrations. The release curves were found to be well represented by the Weibull equation.
