This SPR sensor employs surface electromagnetic evanescent waves Based on the specific binding activity to NPs, a quantitative assay was performed using a surface plasmon resonance (SPR) biosensor. From the doseresponse curve, the binding constant (Kd) was calculated to be 185 pM and the limit of detection was estimated to be 1.02 pM. Since surface plasmon resonance (SPR) biosensor was first introduced in the early 1990s, it has proven to be one of the most powerful technologies for determining specificity, affinity, and kinetic parameters during binding of macromolecules in many types of bonds, including protein–protein (Kim et al., 2006), protein–DNA (Majka and Speck, 2006), enzyme–substrate or inhibitor (Fong et al., 2002), receptor drug (Rich et al., 2002), lipid membrane–protein (Erb et al., 2000), protein A highly sensitive surface plasmon resonance-based PCF biosensor is explored in this research work. Outside the fiber frame, active plasmonic material gold (Au) with a thickness of 25 nm has been deposited which is chemically steady and is the primary sensing layer of the presented sensor.
