Sensing & Biosensing Application 

As the nanometer sized particles show extraordinary properties, the deliberate utilization of nanoparticles for sensing, biosensing and optical sensing have been explored. 

  • Electrochemical Sensors

The nanoparticles have been self-assembled on the electrode surface using thiol functionalized silicate network or composite materials on electrode platform for various electrochemical applications. The nanoparticle modified transducer has been used as a sensor for sensing of bioanalytes (e.g. Glucose, Ascorbic acid, Uric Acid, NADH, Neurotrasmitters(Dopamine) etc as well as used for speciation of environmental pollutants such as arsenic, mercury, chromium, lead and etc.

  • Electrochemical Biosensors

The integration of Nanoparticles and oxidase/dehydrogenase enzyme with the sol-gel derived silicate network or 2D matrix have carried out for the development of amperometric biosensors. The electrocatalytic activity of Nanoparticles has combined with the enzymatic activity of enzymes to develop enzymatic biosensor. The integrated biosensor shows fast and stable amperometric response towards analytes of interest. The biosrnsor has proved its potential application for real sample analysis.

  • Optical Sensors

The coinage metal nanoparticles with well-defined nanostructure have become one of the most active research areas in the past decades. The gold nanoparticles received considerable attention in different areas such as chemical and biological sensing, medical diagnostics and therapeutics and biological imaging, as these small particles exhibit strong surface plasmon resonance absorption. The fascinating optical properties of gold nanpparticles make it an ideal color-indicating candidate for signaling molecular recognition events.

  • Photoelectrochemical Sensors

In fact, hybridization of semiconductor nanomaterials with plasmonic nanostructures has been widely investigated for their excellent performance in photocatalytic conversion. It was well observed that the catalytic efficiency of semiconductor materials get down to 10% during the photocatalytic process due to the recombination of photo generated excitons. In order to avoid this recombination and to increase the photocatalytic performance, the semiconductor nanoparticles are hybridized with plasmonic metal nanoparticles, while the plasmonic nanostructures play as a reservoir for the photo generated electrons and enhances the interfacial charge separation processes. Here we have given our effort for synthesis of photoelectro-active materials and explore the optical and electrochemical properties.
