Abstract:
We proposed a terminal deoxynucleotidyl transferase (TdT)-assisted rolling circle amplification (RCA) strategy for the amplified detection of genome-containing biological targets. The synergetic signal amplification of DNase I-mediated genomic DNA fragmentation and subsequent RCA allow the sensing platform to have extraordinarily high sensitivity.
