Novel mechanisms for selenite biotransformation and selenium nanoparticles biogenesis in Acinetobacter sp. SX5 isolated from seleniferous soil.

The high biotoxicity of selenium (Se) has spurred research into its microbial biotransformation into less toxic Se nanoparticles (SeNPs). However, the molecular mechanisms underlying microbially driven selenite transformation remain largely unknown. In the present study, Acinetobacter sp.

Decellularised extracellular matrix-based injectable hydrogels for tissue engineering applications.

Decellularised extracellular matrix (dECM) is a biomaterial derived from natural tissues that has attracted considerable attention from tissue engineering researchers due to its exceptional biocompatibility and malleability attributes. These advantageous properties often facilitate natural cell infiltration and tissue reconstruction for regenerative medicine. Due to their excellent fluidity, the injectable hydrogels can be administered in a liquid state and subsequently formed into a gel state in vivo, stabilising the target area and serving in a variety of ways, such as support, repair, and drug release functions.

A water-stable Eu-based MOF as a dual-emission luminescent sensor for discriminative detection of nitroaromatic pollutants.

A water-stable Eu-based metal-organic framework (MOF) with dual-emission luminescence behavior, namely {[Eu(INO)(μ-OH)Cl(HO)]·(NO)·(HO)} (Eu-MOF; HINO = isonicotinic acid N-oxide), was successfully constructed by the solvothermal reaction of Eu ions with the organic ligand HINO. The cationic 3D framework contains microporous channels with accessible Lewis-base sites and NO ions as balanced anions, which all contribute to the selective detection of multifarious analytes. This MOF shows ratiometric detection of acetone, CrO ions, and nitroaromatic compounds (NACs).
