title: An ultrasensitive electrochemical impedance sensor for a special BRCA1 breast cancer gene sequence based on lambda exonuclease assisted target recycling amplification.
abstract: A label-free, target recycling electrochemical impedance spectroscopy (EIS) DNA sensor has been developed for detection of a model related to the BRCA1 breast cancer gene with a detection limit of 0.05 nM.
