One‐Step Immobilized Phage Depolymerase Coatings for Catheter‐Related Bloodstream Infections

Advanced Science, EarlyView.
Catheter‐related bloodstream infections (CRBSI) caused by drug‐resistant Gram‐negative bacteria remain a major clinical challenge. Here, a polydopamine‐assisted depolymerase coating degrades bacterial capsules and restores serum‐mediated killing, effectively suppressing biofilms and reducing bacterial burden in vitro, ex vivo, and in vivo, presenting a

Mesoporous PU/PEDOT:PSS Electrodes Reveal Population‐Level Stochastic Bioelectrical Dynamics in Marine Diatoms

Advanced Science, EarlyView.
Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

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 ...
