Enhanced Sonodynamic Bacterial Elimination and Wound Healing Therapy Based on Lanthanide Ion Doped Bi2WO6 Nanosheets and Hydrogel Platform

Advanced Functional Materials, EarlyView.
Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...

Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...
