We report surface-enhanced Raman scattering (SERS) activities of 2D Niobium Carbide (Nb2CTX) MXene measured with a laser excitation of 532 nm, using methylene blue (MB) and crystal violet (CV) as probe molecules. The results showed that the Raman enhancement of the dye molecules on Nb2CTX-based SERS platform was heavily dependent on the laser-molecule combination, giving a higher Raman enhancement for CV than for MB at 10-4 M concentration. A significant difference in the Raman enhancement for two dyes indicates a possibility of selective SERS sensing on 2D Nb2CTX. The results clearly infer that the charge transfer interaction plays a major role in the SERS mechanism. Our findings provide an insight into the development of inexpensive, and selective SERS platforms based on 2D MXenes for molecular detection
