Abstract Urinary‐based infections affect millions of people worldwide. Such bacterial are mainly caused by Escherichia coli (E. coli) biofilm formation in the bladder and/or urinary catheters. Herein, authors present a hybrid enzyme/photocatalytic microrobot, based on urease‐immobilized TiO 2 /CdS nanotube bundles, that can swim urea as biocompatible fuel and respond to visible light. Upon illumination for h, these microrobots able remove almost 90% biofilm, due generation reactive radicals,...
High-entropy materials, with complex compositions and unique cocktail characteristics, have recently drawn significant attention. Additionally, a family of sodium super ion conductors (NASICONs)-structured phosphates in energy storage areas shows comprehensive application for traditional alkaline batteries and, particular, solid-state electrolytes. However, there is no precedent fabricating this kind NASICON-type high-entropy phase. Here, we report the successful fabrication two...
Atomic-level defects in van der Waals (vdW) materials are essential building blocks for quantum technologies and sensing applications.
