Ultrasensitive detect of CA125 based on triple signal amplification strategy with huge amount of loaded probes via exonuclease cyclic cleavage, rolling cyclic amplification and strand self-growth

A novel electrochemiluminescence(ECL) aptamer biosensor with high sensitivity and selectivity for the detection of tumor biomarker carbohydrate antigen CA125 was constructed, and a strategy of triple amplification of signals was...
