Multifunctional Protein Eutectogels Based on Polyphenolic: Zwitterionic Low‐Transition‐Temperature Mixtures

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the first example of multifunctional protein eutectogels based on a tannic acid: betaine low‐transition‐temperature mixture, exhibiting elastomeric behavior, strong adhesion to various substrates, including biological tissues, and notable anti‐inflammatory properties derived from the natural polyphenol and zwitterion.

Displacement MMG-based estimation of dynamic muscle viscoelasticity in the quadriceps during passive pedaling

open access: yesScientific Reports
We explore the correlation between muscle viscoelasticity and displacement mechanomyography (DMMG) during passive joint movement. Current methods for assessing muscle viscoelasticity (which is essential for rehabilitation and sports conditioning) are ...

Liquid Metals as Initiators of Free‐Radical Polymerization of Hydrogels: A Perspective

open access: yesAdvanced Functional Materials, EarlyView.
Gallium‐based liquid metals initiate free radical polymerization to form hydrogels without the use of toxic molecular initiators. In addition to initiating polymerization, they can act as crosslinkers, yielding softer, more extensible, and tougher hydrogels than those formed with conventional initiators.

Harnessing Mechanical Stress with Viscoelastic Biomaterials for Periodontal Ligament Regeneration

open access: yesAdvanced Science
The viscoelasticity of mechanically sensitive tissues such as periodontal ligaments (PDLs) is key in maintaining mechanical homeostasis. Unfortunately, PDLs easily lose viscoelasticity (e.g., stress relaxation) during periodontitis or dental trauma ...
