An electrochemiluminescence ratiometric self-calibrated biosensor for carcinoembryonic antigen detection
10.1016/j.jelechem.2018.02.052 2018-02-24 Owing to the difficulty to find a matched donor/acceptor pair, the development of an accurate and sensitive electrochemiluminescence (ECL) ratiometric sensing strategy based on resonance energy transfer (RET) strategy is still challenging. Herein, RET strateg... |
