Mechanoactive Biomaterials for Cell–Matrix Mechanotransduction
Advanced Materials, EarlyView.The graphical abstract shows how individual triggers (force, light, or temperature) and combined optothermal or receptor‐targeted actuation induce material responses at the tissue, cellular, and receptor scales. Their spatial (global or focused) and temporal (continuous or cyclic) modulation determines the resulting mechanical output.

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration
Advanced Materials Interfaces, EarlyView.The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Advanced Materials Technologies, EarlyView.In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...

Thermo-responsive gels that absorb moisture and ooze water
Nature Communications, 2018 Most smart hydrogels are used in their wet state and determination of their phase transition behaviour in the dried state is lacking. Here the authors investigate the thermo-responsive behaviour of an interpenetrating polymer network gel comprising of ...

Bioartificial polymeric materials based on collagen and poly(N-isopropylacrylamide)
Materials Research, 2007 Films of collagen (CLG) and poly(N-isopropylacrylamide), PNIPAAm, were prepared by casting from water solutions. These bioartificial polymeric materials were studied to examine the influence of PNIPAAm content and glutaraldehyde vapor cross-linking on ...
