- Rolling Circle Amplification (RCA) has shown significant potential for pathogen diagnostics providing high specificity and sensitivity combined with relatively low temperature (<37 °C) isothermal amplification. In the context of the ongoing COVID-19 pandemic, we report the development of an RCA-based method allowing direct detection of SARS-CoV-2 RNA in microfluidics. The viral RNA was hybridized to biotinylated oligos and L-probes in solution, enriched in a microchannel and subsequently amplified in situ using padlock probes against the L-probes. This method allowed the detection of 1x103 viral copies/μL within 90 minutes of amplification, demonstrating an alternative approach to current isothermal amplification methods.
