Fabrication of Cu-hemin metal-organic-frameworks nanoflower supported on three-dimensional reduced graphene oxide for the amperometric detection of H2O2

One-step synthesis of nanosilver embedding laser-induced graphene for H2O2 sensor

“…It has good optical, biocompatibility and electronic effects, and has important application prospects in many aspects [25] , [26] , [27] , [28] . GO and precious metal based composites are widely used for H 2 O 2 detection due to their good electrical conductivity and electrochemical activity [29] , such as ITO-rGO-AuNPs [30] , Ag@ -MnO 2 /GCE [31] , Pt/Fe 3 O 4 /GO [32] and Cu-hemin-MOFs/3D-rGO [33] . It is found that the deposition of metal and metal oxide on rGO can effectively increase the electrocatalytic ability [34] .…”

A Versatile Chemoenzymatic Nanoreactor that Mimics NAD(P)H Oxidase for the In Situ Regeneration of Cofactors

“…The accumulation of hydrogen peroxide in the reaction medium can poison and concomitantly inactivate both the DH enzyme and the hemin itself [15] . In this regard, experimental designs that hold the concentration of the hydrogen peroxide low, together with the development of supramolecular approaches that foster the activity of hemin molecules and protect the (bio)catalyst from inactivation, are of high interest [16] …”

“…[15] In this regard, experimental designs that hold the concentration of the hydrogen peroxide low, together with the development of supramolecular approaches that foster the activity of hemin molecules and protect the (bio)catalyst from inactivation, are of high interest. [16] The arrangement of (bio)catalysts in spatially confined environments is currently being explored to facilitate the design of efficient chemical reactions. [17,18] Confined architectures seek for the optimization of the substrate-product diffusion pathways, which ameliorates the overall catalytic activity of multicatalytic systems and reduces mutualinactivation events.…”

Metal–organic frameworks (MOFs) as apt luminescent probes for the detection of biochemical analytes

“…In addition, the introduction of 3D-RGO effectively enhanced the electrical conductivity of Cu-hemin MOFs, thereby exhibiting good electrochemical properties towards H 2 O 2 and enabled in situ real-time detection of H 2 O 2 release from living cells. 52 Yang et al designed a sensitive sensor, MIL-47(V)-OH, in the presence of negatively charged superoxide ions, that selectively and sensitively detected H 2 O 2 . Interestingly, by adjusting the ligand in particular by replacing 2-amino terephthalic acid with the 2,5-dihydroxy terephthalic acid of MIL-47(V), the reaction was accelerated at least by a factor of 10 times.…”
