a SERS spectra of R6G (10–3 M) with ML-Ti3C2Tx and FL-Ti3C2Tx. b SERS spectra of R6G (10–6 M) with Ag/ML-Ti3C2Tx and Ag/FL-Ti3C2Tx. c Schematic diagram of electron transfer from FL-Ti3C2Tx to Ag NP due to their work function difference. Wm and Ws represent the work functions of Ag NP and FL-Ti3C2Tx, respectively
