A metal–organic framework with multienzyme activity as a biosensing platform for real-time electrochemical detection of nitric oxide and hydrogen peroxide

Abstract

Metal-Organic Framework (MOF) with large surface area, exposed active site, excellent catalytic performance and high chemical stability has been used as artificial enzymes and designed for nonenzymatic electrochemical sensors. Here,...

In situ fabricated MOF–cellulose composite as an advanced ROS deactivator-convertor: fluoroswitchable bi-phasic tweezers for free chlorine detoxification and size-exclusive catalytic insertion of aqueous H2O2

“…To check the quick and discriminative sensing efficacy of the framework for onsite application, 50,51 suitably sized Whatman filter paper strips were encrusted with aqueous MOF dispersion and air-dried. Under a hand-held UV-light (365 nm), bright bluish-white emission of the paper strip (Fig.…”

Deciphering the role of functional synergy in a catalytic molecular assembler: a proof of concept for boosted catalysisviaretrosynthetic linker scissoring

“…26 Alternatively, suitable functionalization of the MOF surface with electroactive struts critically reinforces OERs via facile migration of generated electrons. 27 In a parallel manner, MOFs have progressively gained importance as powerful heterogeneous catalysts, owing to the existence of task-specific functionalities that activate substrate molecules. 28,29 Moreover, their optimized channels lead to much anticipated pore-fitting-induced size selectivity.…”

Ionic liquid functionalized metal–organic framework nanowires for sensitive and real-time electrochemical monitoring of nitric oxide released from living cells

“…To date, various nanomaterials such as metal/metal oxide nanoparticles (NPs), 9,12 carbon materials 10,13 or carbon materials modied with metalloporphyrins or ionic liquids, 14,15 metal-organic frameworks (MOFs), 16,17 and single-atoms 18 have been reported for NO detection and produced a susceptible signal response to external changes. Among these, MOFs, as emerging hybrid nanomaterials, have attracted growing interest due to their porous structure, good biocompatibility, exposed activity sites, and tunable size.…”
