Popis:	We design a D-shaped photonic-crystal fiber (PCF) based on surface plasmon resonance (SPR) for the detection of cancer cells. It is coated with layers of gold (Au) and molybdenum disulfide (MoS2). Au layer is used to accurately determine the spectral sensitivity in the visible region. The analyte is placed over MoS2 layer. The sensitivity of the sensor is enhanced with the help of MoS2. The designed sensor is highly suitable for detecting cancer cells having refractive indices 1.45 and 1.46. The proposed sensor exhibits a maximum sensitivity of 3000 nm/RIU.
