(a) Schematization of the ultrasonication process for obtaining 2D-MoS2 nanosheets; (b) SEM images showing 2D-MoS2 deposited on the surface of a gold electrode; (c) Raman spectra carried out at 785 nm. The Inset shows the intensity of the Raman band as a function of MoS2 loading. Adapted with permission from reference [49].
