evelopment of nanostructured materials with superior morphology by simple methodology has
incessantly received a significant scientific interest due to their unique physical and chemical properties
for the applications in electrochemical sensors and biosensors. Binary metal oxides, particularly, metal
molybdates and tungstates possess enormous attentions due to their high electrical conductivity, excellent
structural stability and reproducibility compared to single one. In this regard, author fabricated different metal
molybdates and tungstates with well-defined morphology and utilized as chemical sensors and biosensors in
real environment and biological fluids. For occasion, two-dimensional plate-like tin molybdate was fabricated
via simple co-precipitation route and employed as an electrochemical for the detection of neurotoxicity drug
clioquinol. Highly sensitive and selective electrochemical sensor for the identification of postharvest scald
inhibitor diphenylamine was developed using seed-like strontium molybdate modified electrode. A flower-
like neodymium molybdate was prepared and studied towards the selective electrochemical sensor for the
antibiotic drug nitrofurantoin. The CoWO4 nanospheres was prepared by low temperature chemical synthesis
method and evaluated towards the sensitive detection of glucose biosensor. A novel nickel tungstate was
synthesized using simple hydrothermal treatment without using any surfactant or templates and investigated
for its electrochemical properties for the detection of glucose biosensor. Well-crystalline 2D cerium tungstate
nanosheets were prepared by a simple wet chemical approach and used as an excellent electron mediator for
the fabrication of nitrite sensor. A novel ruthenium nanoparticles decorated tungsten oxide based sensor was
developed and its catalytic behaviorwas demonstrated towards theoxidationof hydrazine.The aforementioned
nanomaterials were furnished a good electrocatalytic activity with appreciable stability towards the chemical
sensors and biosensors when compared with the previously reported sensors. The analytical parameters such
as linear response range, sensitivity, limit of detection and reproducibility of the devices also been carried out
and compared with the current state of the art.
