Synthesis of Tungstate based Nanomaterials for Photocatalytic and Biosensing Applications

Various tungstate based nanomaterials such as barium tungstate (BaWO4) , bismuth tungstate (Bi2WO6), zinc tungstate (ZnWO4) etc were synthesized using facile, efficient and cost effective Hydrothermal Technique. These nanomaterials were characterized using high tech facilities like SEM, XRD, EDS, TEM, etc. Later these materials were explored for their potential applications in photocatalytic degradation of harmful compounds, organic dyes, waste materials under artificial light and sunlight.


Bismuth tungstate (Bi2WO6) and zinc tungstate (ZnWO4) were further investigated for their detection applications. MWCNTs/Bi2WO6 nanocomposite was used as a sensor coating for the mass-sensitive detection of rifampicin (RIF).

This nanocomposite was employed as a transducer layer for RIF onto the QCM sensor and multiple studies were directed to bring out the sensing characteristics of the material as well as to have a preliminary understanding of the selectivity. The developed sensor showed high sensitivity toward rifampicin, excellent reproducibility and stability. Similarly, one dimensional (1D) nanostructures of ZnWO4 were employed for the detection of a model antibiotic, chloramphenicol. The developed sensor exhibited excellent limit of detection, 0.32 μM and 100%

specificity as compared to its structural and functional analogues such as thiamphenicol and clindamycin. This work can broaden new opportunities for the researchers to explore unconventional nanomaterials bearing unique morphologies and quantum phenomenon for the label-free detection of other bioanalytes.


It is necessary to study the possible interactions among various chemical surfaces and analytes before applying them to biological systems. Carbon nanotubes- iron oxide (SPIONs-CNT) nanocomposite was synthesized by using lecithin stabilized superparamagnetic iron oxide nanoparticles (SPIONs) obtained by facile hydrothermal technique. Various characterizations of the obtained nanocomposite were carried out and electrochemical studies were performed further to study the interaction capabilities of the nanocomposite with anti-TB drug Rifampicin. Obtained results by cyclic voltammetric studies of SPIONs-CNT nanocomposite with limit of detection (LOD) of 1.178µM showed the enhanced electrochemical sensitivity and selectivity of anti-tuberculosis (anti-TB) drug Rifampicin (Rif).
