Sensitive electrochemical detection of l-cysteine based on a highly stable Pd@Ti3C2Tx (MXene) nanocomposite modified glassy carbon electrode

A sensitive and selective electrochemical sensor is reported for the detection of l-Cys based on a Pd@Ti₃C₂T_x (MXene) composite modified GCE. The deposition of PtNPs on the MXene has improved the electrochemical stability of the MXene at the applied potential.
