Affinity Peptide-based Electrochemical Biosensor for the Highly Sensitive Detection of Bovine Rotavirus.

ABSTRACT: Bovine diarrhea is a major concern in the global bovine industry because it can cause significant financial damage. Of the many potential infectious agents that can lead to bovine diarrhea, bovine rotavirus (BRV) is a particular problem due to its high transmissibility and infectivity. Therefore, it is important to prevent the proliferation of BRV using an early detection system. This study developed an affinity peptide-based electrochemical method for use as a rapid detection system for BRV. A BRV-specific peptide was identified via the phage display technique and chemically synthesized. The synthetic peptide was immobilized on a gold electrode through thiol-gold interactions. The performance of the BRV specific binding peptides was evaluated using square wave voltammetry. The developed detection system exhibited a low detection limit (5 copies/mL) and limit of quantitation (2.14 × 10² copies/mL), indicating that it is a promising sensor platform for the monitoring of BRV.
