Application:

Transparent sodium polytungstate polyoxometalate aquatic shields toward effective X-ray radiation protection: Alternative to lead glasses.: This study explores the development of transparent sodium polytungstate polyoxometalate-based shields for effective X-ray radiation protection. The research demonstrates that these aquatic shields can serve as a non-toxic alternative to traditional lead glasses, offering high transparency and efficient radiation attenuation. This makes them suitable for various applications in medical and industrial X-ray protection (Hashemi et al., 2022 ).

Hybrid of sodium polytungstate polyoxometalate supported by the green substrate for photocatalytic degradation of auramine-O dye.: This paper investigates the photocatalytic properties of sodium polytungstate polyoxometalate supported on a green substrate for the degradation of auramine-O dye. The study highlights the efficiency of this hybrid material in environmental applications, particularly in wastewater treatment, by utilizing photocatalytic processes to break down harmful dyes (Mousavi et al., 2022 ).

Bioinorganic Synthesis of Sodium Polytungstate/Polyoxometalate in Microbial Kombucha Media for Precise Detection of Doxorubicin.: This research presents a novel biosensor developed using sodium polytungstate/polyoxometalate synthesized in a microbial kombucha medium. The biosensor shows high sensitivity and precision in detecting doxorubicin, a chemotherapeutic drug, in biological fluids. This innovative approach enhances the biosensor′s performance, making it suitable for clinical applications in drug monitoring and pharmacokinetics studies (Mousavi et al., 2022 ).
