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
