The rapid spread of viral zoonoses can cause severe consequences, including huge economic loss, public health problems or even global crisis of society. Clinical detection technology plays a very important role in the prevention and control of such zoonoses. The rapid and accurate detection of the pathogens of the diseases can directly lead to the early report and early successful control of the diseases. With the advantages of being easy to use, fast, portable, multiplexing and cost-effective, semiconductor biosensors are kinds of detection devices that play an important role in preventing epidemics, and thus have become one of the research hotspots. Here, we summarized the advances of semiconductor biosensors in viral zoonoses detection. By discussing the major principles and applications of each method for different pathogens, this review proposed the directions of designing semiconductor biosensors for clinical application and put forward perspectives in diagnostic of viral zoonoses.

Viral diseases represent one of the major threats for salmonids aquaculture. Early detection and identification of viral pathogens is the main prerequisite prior to undertaking effective prevention and control measures. Rapid, sensitive, efficient and portable detection method is highly essential for fish viral diseases detection. Biosensor strategies are highly prevalent and fulfill the expanding demands of on-site detection with fast response, cost-effectiveness, high sensitivity, and selectivity. With the development of material science, the nucleic acid biosensors fabricated by semiconductor have shown great potential in rapid and early detection or screening for diseases at salmonids fisheries. This paper reviews the current detection development of salmonids viral diseases. The present limitations and challenges of salmonids virus diseases surveillance and early detection are presented. Novel nucleic acid semiconductor biosensors are briefly reviewed. The perspective and potential application of biosensors in the on-site detection of salmonids diseases are discussed.
