Abstract: A method of forming a chemically reactive membrane includes applying a first solution to a structure, the first solution includes a macrocyclic ligand having electron-donating ligands and a side functional group for crosslinking, crosslinking a plurality of the macrocyclic ligand to form a first network of crosslinked macrocyclic ligands, and applying a second solution to the structure, the second solution comprising a catalytic center. Each catalytic center complexes with the electron-donating ligands of each macrocyclic ligand to form catalytic sites in the first network of crosslinked macrocyclic ligands.

Abstract: Provided herein are novel monoclonal antibodies and antibody fragments with improved binding to and/or neutralization against multiple SARS-CoV-2 variants, e.g., Omicron lineages. Also provided are compositions and biosensors comprising the monoclonal antibodies and antibody fragments and methods of using the novel monoclonal antibodies and antibody fragments for treating, preventing, and diagnosing COVID-19 and detecting SARS-CoV-2.

Abstract: A membrane includes a first layer, and a second layer coupled to the first layer. The second layer includes a network of catalytic sites, each catalytic site having a catalytic center characterized by promoting a chemical reaction of a target material.

Abstract: Novel compositions of matter based on homopiperazine precursor materials and forming a homopiperazine-based ligand are disclosed, along with suitable techniques and materials for the synthesis and utilization thereof. In particular various synthetic schemes and techniques for applying the disclosed compositions of matter as a decontaminating agent. The decontaminating agents include homopiperazine-based ligand-metal complexes that are particularly effective at neutralizing toxicity of nerve agents, pesticides, and other toxic organophosphorus-based compounds. In preferred approaches, the homopiperazine-based ligand-metal complexes act as catalysts to facilitate substitution of a leaving group of the organophosphorus-based compound with a functional group that does not permit the organophosphorus-based compound to inactivate acetylcholinesterase upon introduction of the organophosphorus-based compound to a living organism such as insects and mammals.

Abstract: A catalyst includes a bis(2-pyridylmethyl)amine-based ligand. A method of forming a catalyst, may include: reacting bis(2-pyridylmethyl)amine-based compound with a terminal azide and/or a terminal alkyne in the presence of Cu(I) to form a bis(2-pyridylmethyl)amine-based ligand. A method of using such catalysts may include neutralizing toxicity of at least one organophosphorus-based compound by reacting the organophosphorus-based compound with a bis(2-pyridylmethyl)amine-based ligand-metal complex.
