Two kinds of electrochemical impedimetric biosensors for the detection of E. coli O157: H7
are described and compared. They were fabricated using self-assembled layers of thiolated …

abstract A novel and sensitive colorimetric method for assay of Escherichia coli O157: H7
was developed as a model for Gram-negative bacteria by a mercaptoethylamine-modified …

Abstract Background Escherichia coli O157: H7 is one of the major foodborne bacterial
pathogens and also a biodefense agent. To ensure food safety and public health, it is very …

A novel, label-free amperometric immunosensor has been developed for the rapid detection
of heat-killed Escherichia coli O157: H7 (E. coli O157: H7). This immunosensor was …

We intended to develop a novel biosensor using gold nanoparticles (AuNPs) for indicating
different concentrations of E. coli O157: H7 and smart phone imaging APP for monitoring …

Gold nanoparticles (AuNPs)-based lateral flow strip (LFS) enables a quick screening of
foodborne bacteria in point-of-care (POC) diagnostics but suffers from the cumbersome …

Food poisoning microorganisms that contaminate food products and compromise food
safety and security have been considered a major health threat and a serious concern for …

In this study, gold nanoclusters (AuNCs) in the presence of chitosan were prepared assisted
by UV irradiation, which exhibit peroxidase-like property tested with H 2 O 2/3, 3, 5, 5 …

A pH-triggered colorimetric assay has been established by using aptamer anchored gold
nanoparticles to detect Escherichia coli O157: H7 (E. coli O157: H7). Gold nanoparticles …

Bacteria are unambiguously menacing for community healthiness globally. The common
reservoirs of bacteria are contaminated foods, animals, polluted water and soil. There are …
