Human serum albumin-based cryogels as a biomimetic platform for 3D co-culture and drug-induced liver injury prediction.

Nonclinical toxicity testing in rodent and nonrodent models often fails to predict human pharmacological responses, and the reliance on poorly characterized biomaterials hinders clinical translation in drug development. To address these limitations, we engineered a human serum albumin methacryloyl (HSAMA) cryogel system incorporating key liver extracellular matrix (ECM) components, collagen I (C) and fibronectin (F), to mimic the liver's architectural complexity. By co-culturing HepG2 and HUVECs within the HSAMA-CF cryogel, we created a three-dimensional, large-pore scaffold that facilitates critical hepatocyte-endothelial cell interactions essential for liver function and drug metabolism.

An Efficient Ultra-Narrowband Yellow Emitter Based on a Double-Boron-Embedded Tetraazacyclophane.

Ultra-narrowband and highly modifiable multiple resonance thermally activated delayed fluorescence (MR-TADF) materials are crucial for realizing high-performance wide-color-gamut display applications. Despite progress, most MR-TADF emitters remain confined to blue and green wavelengths, with difficulties extending into longer wavelengths without significant spectral broadening, which compromises color purity in full-color organic light-emitting diode (OLED) displays. In this work, we present a novel tetraazacyclophane-based architecture embedding dual boron atoms to remarkedly enhance intramolecular charge transfer through the strategic positioning of boron and nitrogen atoms.
