In this work, we firstly enunciated the presence of synergy effect between the electron and energy transfer in an electrochemiluminescence (ECL) system involving the CdS NCs and Au NPs, based on which an amplified ECL biosensor was constructed for se

A new “signal-on” aptasensor for ultrasensitive detection of Ochratoxin A (OTA) in wheat starch was developed based on exonuclease-catalyzed target recycling. To construct the aptasensor, a ferrocene (Fc) labeled probe DNA (S1) was immobilized on

A novel switch-cytosensing strategy has been designed, which is based on the changes of electron transfer efficiency between ferrocene at the end of DNA and the electrode surface before and after cell transfection. This strategy provided a general an
