Surface plasmonic resonance (SPR) sensor based on SiO2/Au (40 nm) chip with CVD, MBE and exfoliated MoS2. (a) The reflectance of SPR sensor for different layer numbers of CVD, MBE, and exfoliated MoS2. (b) The dependence of the SPR sensor sensitivity on the MoS2 number of layers. The inset is a scheme of an SPR sensor.
