Electrochemiluminescent system based-on novel semi-sandwich Lanthanide metal complex with 3D rod-like nanoflowers In2O3/ZnIn2S4 as co-reaction accelerator for kanamycin detection

Xiaoyi Duan et al.

Summary: By using a novel semi-sandwich phthalocyanine (Pc) gadolinium complex as a luminophore and 3D flower-like nanorods In2O3/ZnIn2S4 as a co-reactant accelerator (CRA), an electrochemiluminescent (ECL) apta-sensor with highly sensitive signal amplification was created. The Pc-Gd complex showed enhanced luminescent property due to the antenna effect of its 18-electron conjugated macrocycle ligand. The design and configuration of the In2O3/ZnIn2S4 tubular heterogeneous structure accelerated charge transfer and provided more active sites, resulting in increased luminophore loading and shortened transmission distance. The developed biosensor exhibited superior kanamycin detection performance with a wide detection range and a low detection limit.

Direct Visualization of Nanoconfinement Effect on Nanoreactor via Electrochemiluminescence Microscopy

Xuedong Huang et al.

Summary: Nanoconfinement in mesoporous nanoarchitectures can significantly influence molecular transport and reaction kinetics in electrochemical processes. A comprehensive understanding of nanoconfinement and mass transport is crucial for practical applications, but a proper approach to study it is currently lacking. In this work, we present a single nanoreactor electrochemiluminescence (SNECL) microscopy technique that utilizes Ru(bpy)(3)(2+)-loaded mesoporous silica nanoparticles to directly visualize and investigate the nanoconfinement-enhanced electrochemical reactions at the single molecule level. Additionally, we monitor and simulate the mass transport capability of single nanoreactors with high spatial resolution through analysis of decay time and recovery ability. The nanoconfinement effects in our system also enable the imaging of single proteins on cellular membranes. This SNECL approach could serve as a promising tool for unraveling the nanoconfinement effects during electrochemical processes and bridging the gap between mesoporous nanoarchitectures and potential electrochemical applications.

Biocathodes reducing oxygen in BPE-ECL system for rapid screening of E. coli O157:H7

Bin Chen et al.

Summary: This study demonstrates that E. coli O157:H7 can electrochemically catalyze oxygen reduction at the cathode of bipolar electrode (BPE), resulting in electrochemiluminescence (ECL) reporting intensity change at the anode. Most food matrix does not exhibit catalytic activity for electrochemical reduction of O-2, and their interference with the ECL reaction at the anode is negligible. A low detection limit of 10 CFU mL(-1) for E. coli O157:H7 can be achieved within 1 hour using this system, making it an excellent tool for rapid detection of electroactive bacteria in food.
