Özet

The Border Disease Virus (BDV) is responsible for causing fetal deathly infection, leading to annual occurrences of affected farms. BDV, along with other pestiviruses such as classical swine fever virus (CSFV) and bovine viral diarrhea virus (BVDV), are known to cause major losses in stock farming. These losses can result in reproductive failure, expensive inspections, and other impacts on livestock health. The current detection methods of BDV include various techniques such as RT-PCR, ELISA, VNT, and immunofluorescence assays. These methods, although reliable, may require specialized equipment, time-consuming procedures, and laboratory facilities, making them less suitable for rapid on-site detection. Hence, it is imperative to employ diverse methodologies for detection of BDV. LSPR-based biosensors are a subset of plasmonic biosensors that exhibit numerous advantages for diverse applications. LSPR-based biosensors are particularly well-suited for the production of compact, practical devices for rapid, on-site detection of analytes. The aim of this study is to design and fabricate a biosensor chip utilizing LSPR technology for potential BDV detection. For this aim, glass surfaces were functionalized with gold nanorods modified with a BDV-specific primer sequence, complementary single-strand DNA sequence of 19 bases, and fabricated with PMMA microchannels. Different concentrations of target BDV-DNAsequence ranging from 0.01 pM to 100 nM were exposed to the channels, and the LSPR response was quantified using a Vis-NIR spectrometer. The limit of quantification of the biosensor chips was determined to be 10 pM, while the limit of detection was found to be less than or equal to 1 pM. The sensitivity of the biosensor chips was calculated to be 0.0567 nm/RIU. The dynamic range of the biochips lies between 10 pM to 100 pM.
