We develop a new DNAzyme biosensor for Argonaute 2 (Ago2) assay based on target-initiated rolling circle amplification in combination with an 8-17 DNAzyme-mediated dual signal amplification strategy. This biosensor can achieve ultrahigh sensitivity with a detection limit of 0.35 pM, and it can be further used for the screening of Ago2 inhibitors and the accurate measurement of endogenous Ago2 from HeLa cell extracts.
