miR-122 direct detection in human serum by time-gated fluorescence imaging
Citation: Chem. Commun., 2019, 55, 14958-14961 Abstract A simple method for direct detection of microRNAs (miRs) in human serum without the use of polymerase amplification is presented, achieving low miR-122 concentrations and importantly, discerning effectively single-base sequence mutations. The method is based on the capture of target miRs with synthetic peptide nucleic acid oligomers, dynamic chemical labelling,…
