Nov 24, 2021 · Challenging the TSPCU–NO–MOF composites against 24 h bacterial growth models, the enhanced NO release was found to elicit over 99% reduction in adhered and over 95% reduction in planktonic methicillin-resistant Staphylococcus aureus, with similar results observed for Escherichia coli.

Sep 12, 2024 · The NO adsorption mechanism in MOFs is typically governed by either i) physisorption corresponding to non-bonded host/guest interactions or ii) chemisorption associated with chemical-coordination through open metal sites (OMS) present in the pore walls.

Feb 5, 2025 · We prepared mixed metal copper/nickel metal−organic frameworks of the MOF-74 family, capable of releasing nitric oxide (NO), an important biological signaling molecule, via two methods: rapid burst release from preadsorbed NO and continuous catalytic generation from S-Nitrosoglutathione (GSNO).

Aug 2, 2021 · The MOF facilitates direct reduction of nitric oxide (NO), producing nearly quantitative yields of nitrous oxide (N 2 O) and emulating the reactivity of flavodiiron nitric oxide reductases (FNORs).

Here, a new ultra‐narrow pores Fe bisphosphonate MOF, denoted MIP‐210 (Fe) or Fe (H 2 O) (Hmbpa) (H 4 mbpa = p‐xylenediphosphonic acid) is described that adsorbs NO due to an unprecedented sorption mechanism: coordination of NO through the Fe (III) sites is unusually preferred, replacing bound water, and creating a stable interaction with the fr...

Nov 1, 2024 · This study developed a highly selective and sensitive NO sensor using Ni, Co-MOF-74-CNT-PAN sensor, detecting NO at room temperature with LOD of 18.6 ppb. Integrated into a portable device with a microcontroller and Bluetooth, it enables real-time, home-based monitoring of respiratory diseases.

Herein, we designed and prepared a porphyrin-based MOF (Co-TCPP (Fe)) with rod-like morphology which was assembled with MXene (Ti 3 C 2 T x) through hydrogen bonding to offer a kind of chemiresistive NO sensing hybrid (Co-TCPP (Fe)/Ti 3 C 2 T x).

Jan 1, 2020 · Metal-organic frameworks (MOFs) are expected to offer new opportunities for its sensing. This review is organized to describe the overall advancement made in the MOF-based NOx sensing.

Jan 15, 2024 · Our findings demonstrate that the NO@MOF@PMnO 2 agent exerts significantly potent antibacterial activity against both S. aureus and E. coli, with efficacy rates as high as 92.7 % and 98.4 %, respectively. Accordingly, we propose that NO@MOF@PMnO 2 represents a highly effective method of preventing bacterial infection. Furthermore, our study ...

Jan 20, 2012 · In this account we demonstrate the use of Cu 3 (BTC) 2 as a catalyst for the generation of NO from the biologically occurring substrate, S-nitrosocysteine (CysNO). The MOF catalyst was evaluated as an NO generator by monitoring the evolution of NO in real time via chemiluminescence.
