Summary:Development of Surface Plasmon Resonance (SPR) nanosensors for detection of chemical and biological species has gained considerable momentum, and the number of publications reporting applications of SPR bionanosensors for detection of analytes related to medical diagnostics, environmental monitoring, and food safety and security has grown rapidly. SPR biosensors have become a central tool for characterizing and quantifying biomolecular interactions. Carbon based materials like nanostructured three-dimensionally ordered macro-porous carbon, fullerene, or graphene have been used as transducers in potentiometric sensors. In this article, the authors will discuses the fabrication of SPR nanosensors using the self assembled monolayer technique of thiol compounds on the gold substrate and the chemisorption of gold nanoparticles onto this monolayer for the detection of metal ions such as Cu (II) and the detection of protein. In addition, the fabrication of simple potentiometric sensors for determination of metal ions such as Zn (II) and Ce (III) ions will discuses.
