The role of enzymes and quantum dots in the making biosensor

Rapid and sensitive method ologies for the detection of protein are in urgent requirement for clinicdi- agnostics. Localized surface plasmon resonance (LSPR) of metal nano structures has the potential to circumvent this problem due to its sensitive optical properties and strong electro magnetic near-field enhancements. In this work, an enzyme medi at edplasmonic biosensor on the basis of adual-functional nano hybrid was developed for the detection of thrombin. Enzymes, like glucose oxidase and catalase, were modified with pyrene function-alities and then loaded into the graphene nanodots encaged porous gold electrode via non-covalent stacking interaction between pyrene and graphene..
