Gradients of Aliveness and Engineering: A Taxonomy of Fungal Engineered Living Materials

Advanced Materials, EarlyView.
This paper explores the potential of fungal engineered living materials (ELMs), examining fungal biology and growth mechanisms, which underpin their development. It presents a classification framework based on aliveness, scaffold composition, and engineering degree. Unique properties such as self‐healing, biosensing, and bioremediation are highlighted,

Exploiting pH-Regulated Dimer-Tetramer Transformation of Concanavalin A to Develop Colorimetric Biosensing of Bacteria

Scientific Reports, 2017
Gold nanoparticles (AuNPs) aggregation-based colorimetric biosensing remains a challenge for bacteria due to their large size. Here we propose a novel colorimetric biosensor for rapid detection of Escherichia coli O157:H7 (E.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
