One‐Pot Biphasic Photocatalytic CO2‐to‐Carbonylation Cascades

Angewandte Chemie, EarlyView.
Bioinspired biphasic compartmentalization enables one‐pot cascades where photocatalytic CO2 reduction generates CO for carbonylative cross‐couplings to synthesize complex organic products, including a pharmaceutical. ABSTRACT Photosynthesis compartmentalizes reactions across the thylakoid membrane in vivo to upcycle CO2 into complex chemicals that are ...

Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms

Advanced Science, EarlyView.
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...
