Ti3C2Tx was deposited on a glassy carbon electrode followed by Nafion coating to achieve a robust sensitivity (similar to 3 nM), good selectivity, wide detection window (0.015-10 mu M), high stability, reproducibility, and outstanding recoveries for DA detection in real samples. MXene-based biosensor exhibited much better electrochemical performance when compared with reduced graphene oxide-based biosensor under similar experimental conditions due to the MXenes good electrical conductivity and negatively charged surface which assisted in the selective and sensitive detection of DA.
