Interfacially self-assembled ChOx/HRP proteinosomes for rapid and sensitive cholesterol detection.

This study developed a novel cholesterol biosensing system based on interfacial self-assembled ChOx/HRP dual-enzyme proteinosomes, eliminating the need for complex synthesis. The immobilization of ChOx and HRP on the proteinosome surface enhanced enzyme stability, while the confined spatial proximity of the enzymes significantly improved cascade reaction efficiency, enabling rapid and highly sensitive cholesterol detection.

Rationally-Constructed Porous Nanosheet NiP-NiP Heterostructures for Robust Oxygen Evolution Electrode.

The development of superior non-noble-metal-based oxygen evolution reaction (OER) electrocatalysts is essential for large-scale hydrogen production. In this study, an integrated porous nanosheet NiP-NiP heterostructures were designed as an excellent OER electrocatalyst. The synthesized heterostructures demonstrated notable activity, achieving a small overpotential of 260 mV to sustain a typical 10 mA cm current density, along with exceptional durability over 2000 CV cycles.
