A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

Advanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Photo‐Rewritable Ambipolar Organic Electrochemical Synapses with Bidirectional Optical Plasticity for Adaptive Vision in Aqueous Environments

Advanced Materials, EarlyView.
Photo‐rewritable ambipolar organic synapses operating in aqueous environments at low voltage (≤0.4 V) demonstrate bidirectional optical plasticity through photon‐modulated electrochemical doping. The bulk heterojunction device enables both excitatory and inhibitory responses with extended retention time (>130 min).

Ultrasound‐Responsive Dual‐Prodrug Nanoassembly for “Fenestrae‐Restoration Strategy” in Liver Fibrosis Therapy

Advanced Materials, EarlyView.
ABSTRACT Liver fibrosis is a serious yet reversible intermediate stage in the progression of liver disease, which can ultimately advance to cirrhosis and hepatocellular carcinoma. Targeted and selective inhibition of activated hepatic stellate cells (aHSCs) has emerged as a promising therapeutic strategy for the treatment of liver fibrosis.
