An enzyme-free electrochemical biosensor for sensitive and specific detection of microRNA-21 based on target recycling amplification and non-linear hybridization chain reaction
Abstract A novel electrochemical biosensor with high amplification efficiency was explored for serum microRNA-21 (miRNA-21) detection. This biosensor consisted of the target recycling amplification (TRA) and non-linear hybridization chain reaction (NHCR). When the target miRNA-21 was presented, hair...
