Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions

Advanced Functional Materials, EarlyView.
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

Advanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

Advanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

A Self‐Curling Si3N4‐Biofunctionalized Nerve Wrap for Suture‐Free Peripheral Nerve Repair with Multimodal Regenerative Bioregulation

Advanced Functional Materials, EarlyView.
Si3N4‐enhanced bioactive nanostructured adhesive wrap enables rapid conduit formation in wet environments, simplifying surgical procedures. Incorporated Si3N4 undergoes controlled hydrolysis within nanofibers, multi‐directionally modulating the peripheral nerve repair microenvironment for effective suture‐free repair.
