Single‐Cell Resolution Mapping of Osteoarthritis‐Associated Chondrocyte Dynamics Using a High‐Density CMOS MEA Platform

Advanced Healthcare Materials, EarlyView.
Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...

Protein‐Polymer Dynamic Hydrogels Utilizing Native Ligand Binding for Injectable Therapeutic Delivery and 3D Printing

Advanced Healthcare Materials, EarlyView.
Dynamic nanocolloidal hydrogels were synthesized via the co‐assembly of ligand‐modified spheroidal hyperbranched poly(glycerol) (HPG) and soluble albumin nanoparticles (SANs). Co‐assembly occurred through self‐association of the HPG, as well as its interaction with SANs via native ligand binding.
