Biosensors based on surface plasmon resonance (SPR) have shown significant applications in drug screening, environmental monitoring, immunoassay, etc.; however, improving the sensitivity of these biosensors is one of the prime tasks at present.In this study, taking advantage of the special optical and morphological characteristics of MoS 2 nanoflowers, we synthesized a sensitivity-improved SPR Therefore, a new biosensor for the direct detection of chlorophene in real water is presented, based on surface plasmon resonance (SPR) and using a laccase enzyme as a recognition element. The biosensor chip was obtained by covalent immobilization of the laccase on a gold-coated surface through carbodiimide esters. Surface plasmon resonance (SPR) based sensors are used in biochemistry and biology to detect the molecular concentration, thickness and specific chemical analytes. Surface plasmons are the quanta of surface charge density oscillation [ 2 ] likewise the collective oscillations in electron density at surface of metal whose propagation is confined to metal dielectric interface.
