Vibrio infectious diseases spreading every day through aquatic food may be a life-threatening problem for people with weak immune and growing menace to society. It was estimated that the cost of foodborne diseases was approximately $5–6 billion per year. Traditional methods for Vibrio spp. sensing showed high accuracy but very low detection limit. Immunoassays and nucleic acid-based assays could provide results within 24 h, while they are expensive, labor-cost and tedious. Hence, it was urgently needed for the development of cost-effective, rapid and reliable alternative methods for real-time biosensing of Vibrio spp. Several biosensors have been established for the screening of Vibrio spp. in seafood and water. In this review, we have updated the advances in biosensing assays for screening of Vibrio spp., such as electrochemical, optical and novel nano-scaled aptamers based biosensors. Meanwhile, attentions have been paid on the principal concepts, applications, and examples that have been achieved up to determine Vibrio spp.
