Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

Angewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐

Axial Boron Coordination Reconstructs Stereostructure of Cu Single‐Atom Nanozymes for Efficient Water‐Phase Chemical Sensing

Angewandte Chemie, EarlyView.
Sun et al. proposed an axial boron coordination strategy to reconstruct the stereostructure of Cu SAzymes and enable them to serve as efficient laccase mimics for high‐throughput smart sensor array detection of phenolic pollutants in water phases. ABSTRACT Developing single‐atom nanozymes with stereoconfigurations is a new paradigm for biomimetic ...

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...
