Surprisingly fast assembly of the MOF film for synergetic antibacterial phototherapeutics

Abstract

Synergetic photothermal/photodynamic therapy (PTT/PDT) antibacterial surfaces offer a promising avenue for combating bacterial infections, but generally require a time-consuming and cumbersome chemical preparation procedure. Herein, a metal-organic frameworks (MOF) composite...

The Effect of Linker‐to‐Metal Energy Transfer on the Photooxidation Performance of an Isostructural Series of Pyrene‐Based Rare‐Earth Metal–Organic Frameworks

“…[ 39–42 ] In the former approach, singlet oxygen ( 1 O 2 ) generation by photosensitizing linkers or ligands in MOFs has been studied for the oxidative detoxification of chemical warfare agents, [ 43–45 ] production of commodity chemicals, [ 46 ] as well as for various biological applications. [ 47,48 ] The performance of MOF photosensitizers relies primarily on the identity of the organic linker but can be affected by the identity of the metal nodes due to coupling between electronic energy levels of the organic linker and metal ions. [ 49,50 ]…”

[47,48] The performance of MOF photosensitizers relies primarily on the identity of the organic linker but can be affected by the identity of the metal nodes due to coupling between electronic energy levels of the organic linker and metal ions. [49,50] The use of rare-earth (RE) ions, including Sc(III), Y(III), and the series of fifteen lanthanoids (Ln(III)), has led to the development of RE-MOFs with intricate topologies, some of which have not been achieved using s-, p-, or d-block metal ions.…”

Feathery Tellurium–Selenium Heterostructural Nanoadjuvant for the Synergistic Treatment of Bacterial Infections

“…Therefore, it has become necessary to find a solution to the challenge of developing novel therapeutic approaches that lessen or eliminate the usage of antibiotics . To address this hurdle, phototherapy has been found to offer feasibility for the treatment of bacterial infections due to its high bactericidal efficiency, delayed drug resistance, and ideal penetration . Encouragingly, various nanomaterials with both photothermal conversion ability and free-radical generation ability have been explored as potential nanoagents for phototherapy to enhance antibacterial efficacy. − …”
