A Porphyrin-Based Metal–Organic Framework Nanozyme with Superior Peroxidase-like Activity for Combating Antibacterial Infections and Promoting Wound Healing

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

As an antibacterial agent, H2O2 is widely used to combat pathogenic bacterial infections clinically. To mitigate potential side effects associated with a high dosage of H2O2, it pivotal improve its efficacy. Herein, nanoscale porphyrin-based mesoporous metal-organic framework (MOF) nanozyme, Nano-PCN-222(Fe), was readily prepared by one pot. Nano-PCN-222(Fe) shows striking peroxidase (POD)-like activity comparable that natural enzyme horse radish peroxidase. Such POD-like nanozyme primarily attributed both the monodispersion and accessibility single-atom catalytic sites Fe within framework. consequence ability effectively catalyze decomposition into more toxic hydroxyl radicals, excellent against Gram-negative (Escherichia coli) Gram-positive (Staphylococcus aureus) bacteria assistance H2O2. Remarkably, only 10 mM sufficient fully kill E. coli S. aureus in presence (10 ppm), which significantly lower than actual clinical disinfection (166-1000 mM). Moreover, could accelerate infected wound healing due superior antimicrobial activity. Additionally, no appreciable biotoxicity observed even though up 30 ppm.

Tenon‐and‐Mortise Structure‐Inspired MOF/PVDF Composites with Enhanced Piezocatalytic Performance via Dipole‐Engineering Strategy

Small, Journal Year: 2025, Volume and Issue: unknown

Abstract Fabricating poly(vinylidene fluoride) (PVDF) and its composite ferroelectrics are essential for the development of next‐generation lightweight, portable, wearable, implantable intelligent devices. However, integrating maximizing spontaneous polarization interfacial electromechanical conversion efficiency remain major challenges in contemporary PVDF‐based composites field. Herein, inspired by tenon‐and‐mortise structure associated with ancient Chinese architecture, an amino‐anchored metal–organic framework (MOF)/PVDF piezoelectric using a dipole‐engineering strategy to deliver enhanced piezocatalytic performance is constructed. Homogeneous long‐range ordered hydrogen‐bond networks have been formed PVDF matrix after introducing periodically arranged amino anchors into NH 2 ‐HU MOF. The 10wt% /PVDF exhibits 40% greater β‐phase content remnant value more than 550% higher that bare fibers. These synergistically enhance both local electric field collaborative dipole alignment resulting bactericidal 97.4% when irradiated under clinical ultrasound conditions. Moreover, polarizability within MOF/PVDF simultaneously improves responsiveness X‐rays via periodic anchoring networks, thereby doubling CT imaging efficacy implants at lower voltages. Integrating MOFs polymer matrices through molecular design presents viable approach optimizing ferroelectric properties expanding piezoelectric‐composite applications.
