Description
Summary:Paper nanobiosensors have been established as an excellent platform for analysis of veterinary and human pathogens causing various diseases. Especially, lateral flow assays or biosensors ideal for sensitive, rapid, robust and accurate analysis in laboratory setups and on-site analysis. Viral RNA detection is of great importance for public health as well as animal health protection. In that aspect, the present protocol focuses on the development of functionalized gold nanoparticle-based lateral flow biosensor for fish nervous necrosis virus (Nodavirus) nucleic acids detection. Total viral RNA, isolated from fish samples was subjected to reverse transcription PCR amplification and the amplification products were mixed with specific oligonucleotide probe. A red test line was formed when nodavirus product was present. The proposed assay has great implications on basic research since it eliminates the need for time-consuming, cumbersome electrophoresis protocols and could be adjusted for use on the site of fish culture by fish farmers. Disease monitoring by such bioanalytical platforms without time consuming and costly procedures would have great impact on the aquaculture and environmental safety.
