Abstract: Single atom nanozymes and associated immunoassays, method of making, and method of using such immunoassays are described herein. For example, a method of making a single atom nanozyme includes forming a soft template having multiple nanoscale structures in an aqueous solution and adding a monomer and a metal containing salt into the aqueous solution. The metal containing salt causes polymerization of the monomer to form multiple nanostructures according to the nanoscale structures of the soft template. The method also includes coating the individual formed nanostructures with a confinement layer in the aqueous solution before pyrolyzing. During pyrolysis, the confinement layer at least restricts or completely prevents migration of atoms on the external surface of the individual nanostructures.

Abstract: The disclosure relates to antigen detection reagents and related methods, systems, and kits. The reagents comprise an antigen-binding molecule conjugated to an inorganic component. In some embodiments, the inorganic component possesses catalytic functionality to provide a detectable signal. In some embodiments, the catalytic inorganic component is or comprises a bimetallic nanoparticle. In other embodiments, the inorganic component is a nanoflowers that provides a physical scaffold onto which the antigen-binding component and a reporter component can be loaded, resulting in augmented antigen-binding and reporting capabilities.

Abstract: Materials and methods are described for forming self-assembled peptoid structures that are extremely stable, crystalline, free-standing and self-repairing are described. Based on the peptoid design, peptoid membranes in a 2D arrangement were able to roll into single-walled nanotubes with tunable sizes, diameters, thicknesses and stiffnesses as well as tailorable functions result. Crystalline nanomaterials made through this facile solution crystallization and anisotropic formation process are highly tailorable and exhibit a number of properties advantageous for applications such as water decontamination, cellular adhesion, imaging, surface coating, biosensing, energy conversion, biocatalysis or other applications.
