Engineering a biocompatible chitosan/MOF aerogel for hyperbilirubinemia treatment in liver failure.

Liver failure, marked by a rapid or progressive decline in liver function, leads to complications such as hyperbilirubinemia and infections, contributing to approximately 2 million global deaths each year. Current hemoperfusion methods for hyperbilirubinemia treatment are limited by their low adsorption selectivity and inadequate biosafety, necessitating better treatments. In this study, a chitosan-based HKUST-1 aerogel (HC) was developed as a highly selective, biosafe, and antibacterial adsorbent.

Horseradish Peroxidase-Triggered Polydopamine-Modified Chitosan Hydrogels for Electrically Programmed and Infrared-Decodable Dynamic Information Storage.

The exceptional multiple responsiveness of hydrogels has garnered significant attention for their potential in storing dynamic information. Self-erasing information observable by the naked eye provides an alternative method for data security. Herein, we report a polydopamine (PDA)-modified chitosan (CS) hydrogel that automatically reveals information without external stimuli.
