Hybrid Nanostructure-based Immunosensing for Electrochemical Assay of Escherichia coli as Indicator Bacteria Relevant to the Recycling of Urban Sludge

Carbon Nanotube and Its Derived Nanomaterials Based High Performance Biosensing Platform

“…So, a highly sensitive and selective bacteria sensing system was required, and several bacteria were also successfully detected by using a CNT-based sensing platform. For instance, Zhang et al reported a gold-CNT-based sensing system that could detect Escherichia coli ( E. coli ) through an electrochemical approach [ 222 ]. Firstly, they fabricated the gold-CNT/GCE for the sensing channel.…”

Rapid Immunosensing of Salmonella Typhimurium Using Electrochemical Impedance Spectroscopy: the Effect of Sample Treatment

“…Gold nanoparticles (AuNPs) belong probably to the most convenient labels enabling the signal amplification either through the enlargement of electroactive surface area or due to their electrocatalytic activity . AuNPs also possess biocompatibility and allow for additional modification by other biomolecules (enzymes , antibodies , DNA ) or nanoparticles (magnetic beads ,, quantum dots ). A simple screen‐printed immunosensor for the detection of Salmonella was developed by Fei et al.…”

Functionalized gold nanorod-based labels for amplified electrochemical immunoassay of E. coli as indicator bacteria relevant to the quality of dairy product

“…Among the above techniques, immunoassay-based protocols employing antibody-antigen interaction has been regarded as one of the most important analytical techniques in biological assay [14]. In comparison with other immunological methods such as fluorescence [15], chemiluminescence [16], or surface-plasmon resonance [17], electrochemical immunoassay provides a promising approach for specific and rapid analysis because of the advantages of simple instrumentation, easy signal quantification, low cost of the entire assay, and potential ability for real-time and on-site detection [18][19][20].…”
