Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

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.
