**7. Conclusion**

An extra advantage of the extensive use of nanoparticles in electrosensing techniques can be owed to their exceptional attributes, like remarkable selectivity and sensitivity, high surface energy, capability to show morphological as well as functional diversity, portability, cost-effectiveness, ease-of-construction and easyto-operate. Thus, the merger of electrochemistry and nanotechnology has attributed to a wide range of electro (bio) sensing applications for the detection and quantification of chemical as well as biological target molecules. The role of electrode materials in high-performance electrosensing platforms is crucial and evident. Furthermore, when the simple electrode materials are functionalised with nanostructured and/or nanoengineered materials, significant improvement and enhancement in their conductivity, catalytic activity, biocompatibility, amplification of biorecognition events, acceleration of transduction signal, selectivity, specificity and sensitivity has been observed. Almost every passing day, some new innovation is reported in the field of nano-electrosensing, viz. incorporation of CNTs with metallic NPs aids in the development of highly improved nanocomposites for biosensing applications [86], a dramatic enhancement is observed in the electrical conductivity of rGO (reduced graphene oxide) by incorporation of AgNPs [92], nanowires have an exceptional potential as electrosensing probes because of their high surface-to-volume ratios, reproducibility and extraordinary optical, electrical, and magnetic properties [93], and successful designing of dye-sensitised solar cells based on green zinc oxide nanoparticles [94]. The field of nano-electrochemistry seems to expand its horizon continuously, and despite a significant amount of research done in this field, it just seems to be a new start.
