Coupling Exponential Rolling Circle Amplification to Lateral Flow Devices for Point‐of‐Care Detection of Viral RNA

Angewandte Chemie, EarlyView.
A new exponential RCA (E‐RCA) system was developed and coupled to a toehold system for release of a bridging DNA, allowing for lateral flow detection. The E‐RCA method uses a secondary primer (P2) that binds RCA products (RCAP) to generate extended P2 products that can re‐prime a partially self‐complementary circular template, generating a complete ...
