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

Form factor of pNIPAM microgels in overpacked states

The Journal of Chemical Physics, 2014
We study the form factor of thermoresponsive microgels based on poly(N-isopropylacrylamide) at high generalized volume fractions, ζ, where the particles must shrink or interpenetrate to fit into the available space. Small-angle neutron scattering with contrast matching techniques is used to determine the particle form factor.

CdSe/CdS nanoparticles immobilized on pNIPAm-based microspheres

, 2010
In this work, CdSe/CdS semiconductor ligand-exchanged nanoparticles have been immobilized on poly-(N-isopropylacrylamide) (pNIPAM)-based microspheres. The size and the shrinkage capacity of the spheres can be tuned by the ratio of NIPAM/styrene (pNIPAM ...
