Özet

The Coronavirus disease 2019 (COVID-19) pandemic continues to spread across the world. Thus, there is an urgent need for rapid, simple and accurate tests to diagnose severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.1 The mostly used and reliable method is the RT PCR recommended by the WHO. Since the N gene region is the most conserved and specific, it is important  molecular diagnosis. Compared to the RT PCR method, rapid diagnostic kits have been used as an alternative method because they are easy to use and the short time to get results. 2 For this purpose, our study aimed to determine one region of N gene specific to SARS-CoV-2 with the Lateral Flow Test (LFT) platform. The LFT platform is designed on the basis of hybridization with sandwich model based on Gold nanoparticles (AuNPs). The designed LFT was especially designed for the conserved region of the N gene. AuNPs were conjugated with oligonucleotides complementary to the N gene. Sequences to hybridize to this conjugation product were plotted as test line on the nitrocellulose membrane. The sample containing the target sequence hybridizes with the sequences in the test and control line according to the principle of capillary flow when applied to the sample pad. A red color formation from of AuNPs can be seen by naked eye. According to the research findings designed LFT recognized the SARS-CoV-2 N gene region specifically and turned out to be an alternative to molecular diagnosis
