Abstract :

Norovirus is one of the worldwide infectious diseases by eating raw foods which were infected by others, and there are many people could be infected to touch to be contaminated things by norovirus. It is a major cause of foodborne and nosocomial outbreaks. In this study, thoroughly and highly sensitive biosensors for detecting norovirus by applying a recognized affinity peptide as a platform were described. As this electrochemical and optical methods are cost-effective, fast responsive and easy to integrate information into miniaturized micro-devices like a portable biosensor device. The performance of the peptides has been studied with fluorescent optical assay, and gold-immobilized synthetic peptides has been studying cyclic voltammetry, impedance spectroscopy, and colorimetry analyses. We found that several kinds of peptides (Noro-BP, nonFoul, (FelxL)2, nonFoul(FlexL)2) are the efficient recognizers for norovirus screened by using the M13 phage display method. These peptides were effectively applied to the electrochemical and optical analysis methods to detect the real norovirus sample with rotavirus as a negative control. Among them, nonFoul(FlexL)2 shows the best sensitive performance as the lowest detection limit value of 1.7 copies/mL. In addition, the result could be expected to be useful into the peptide-based detection sensor for the norovirus by using nanoflowers with large surface area. These results suggest that the biosensor consists of specific binding peptide, has affinity to norovirus as a molecular binder and will be used to micro-device as a diagnostic tool. Moreover, the biosensor could be helped as a new biosensing platform for point-of-care testing by applying much more fields. Recent Publications: 1.
