2. Research Interest
The main area of interest is to understand the mechanism of electron exchange from bioactive materials at measurable rate and to use their inherent properties for Sensors design with specific research interest on :
 (1) Thin film Technology: Thin film membrane of controlled porosity covering macrospores to nanoporous and nonporous domain specifically useful for sensor design are one of area of interest. The use of heterocyclic monomers specifically indole and its derivatives through polymerization yielding the polymeric matrix with extreme hydrophobicity at one end and processable hydrophilic polymer on other end is of specific attention. Electropolymerization of other monomers resulting into ion sensing membrane and the use of PVC matrx membrane for solid-state sensor design are of general interest. Nanostructured thin film as organically modified silicate (ORMOSIL) derived from the specific interaction of organic amine and epoxy-groups linked to alkoxysilane has been our main area of interest. The use of reactive organic functionalities in anchoring the noble metal material like palladium through Pd-C and Pd-Si linkage within nanostructured network or encapsulation of nanomaterial/functional material within the nanoporous morphology of ormosil film during sol-gel processing yielding  library of electrocatalytic sites within nanostructured domain for specific applications and the use of metal oxide like TiO2 and WO2 for controlling the performances of ormosil film are of current interest.
 (2) Functional Nanomaterials : The role of organic amine linked to alkoxysilane precursor along with active oxygen containing organic molecules in the synthesis of Au, Ag Pd, Au-Pd, Pd-Au nanoparticles dispersible in a variety of aqueous and non-aqueous solvents displaying both functional ability and nanogeometry during sensor design is of our prime attention. Synthesis of other functional material like processable Prussian blue nanoparticles and it soluble nanocomposite displaying enzyme like behaviour for perfect replacement of HRP is another area of current interest. Functional alkoxysilane medited synthetic incorporation of metla nanoparticle like Ni-Pd, monometal, bimetallic and trimetallic nanoparticles within mesoporous silica nanoparticle/mesoporous material for selective catalytsis and hydrogen evolution reaction.
 (3) Development of Commercial Electrochemical sensors/Biosensors:  Our prime attention is to probe the sensing event at measurable rate based on electrochemical processes for reliable electrochemical biosensor/sensor design having commercial viability involving active role of electron transfer relays, nanomaterials/functional nanomaterials.(see details at http://sensors-vns.com/ Technological designs include our interest on investigating mass and charge transport across membrane matrixes under both linear and non-linear regime and photoelectrochemistry of chlorophyll, bacteriorhodopsin and Prussian blue-ruthenium bipyridyl nanocomposite. The development of display system with suitable electronics along with designing of printed circuit board as per requirement of sensing devices is of specific concern.
