摘要： The invention discloses a biosensor chip and a COVID-19 test kit. The COVID-19 test kit includes a biosensor chip, rolling circle amplification (RCA) primers, RCA padlock probes, and ssDNA conjugated nanoparticles (i.e., ssDNA-NPs probe). In this invention, the surface of the biosensor chip is modified with functional polymers; subsequently, detection ligands are grafted on the modified sensor chip surface to capture the targets. The developed biosensor chip achieves rapid and ultra-sensitive on-site detection of COVID-19 infections. In addition, a signal amplification method is employed using RCA products hybridized ssDNA-NPs probes (i.e., RCA-NPs) complex to amplify the detection signal and to improve the detection sensitivity. The RCA sequence in this invention is designed to generate tandem repeating aptamers and ssDNA-NPs probe hybridization sites so that multiple ssDNA-NPs probes can be hybridized with the RCA products and attached to the captured targets in order to increase the target mass, resulting in detection signal intensification.
