Scanometric nanomolar lead (II) detection using DNA-functionalized gold nanoparticles and silver stain enhancement

A label-free multi-functionalized graphene oxide based electrochemiluminscence immunosensor for ultrasensitive and rapid detection of Vibrio parahaemolyticus in seawater and seafood

“…The sensitivity of methods reported recently for the determination of VP is presented in Table 1. The limit of detection (LOD) of this method, following our previously reported methodology [45], was estimated to be 5 CFU/mL. Considering Preferred position for Fig.…”

Colorimetric Integrated PCR Protocol for Rapid Detection of Vibrio parahaemolyticus

“…Nine kinds of samples including the mixtures of several bacteria, V. parahaemolyticus , V. harveyi , V. mimicus , V. fluvialis , Salmonella typhimurium , Listeria monocytogenes , Staphylococcus aureus , and Campylobacter jejuni , were chosen based on the previous studies [25,26,27,28,29] and detected using our protocol, respectively. From the results in Figure 4a, it could be found that only the samples of the mixture and V. parahaemolyticus could be amplified with the target band with the gel electrophoresis while other non-target samples could not be amplified.…”

An electrochemiluminescence biosensor for mercury ion detection based on gamma-polyglutamic acid-graphene-luminol composite and oligonucleotides

“…of 0.994. According to the method previously reported for indirect detection involving the reduction or quenching of signal [49], the limit of detection (LOD) of this method is estimated to be 0.005 nmol/L (about 0.001 ppb), which was about 3 orders of magnitude lower than the Maximum Contaminant Level in drinking water set by the United States Environmental Protection Agency. Therefore, the proposed method can be used for the ultrasensitive determination of Hg 2+ .…”
