Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels

Advanced Materials, EarlyView.
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

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.
