Аннотация
Zinc oxide nanocrystals-methylene blue nanocomposites were developed by electrodeposition of methylene blue onto the thin films of zinc oxide nanocrystals deposited onto SnO2/F coated glass substrates for in vitro sensing of anti-thalassemic drug i.e. deferiprone. Detailed morphological, electrochemical, structural and optical characterizations of ZnONC-MB/FTO electrode were done using XRD, SEM, EIS, FTIR, LSV, and CV and show quick response time (within 5 s), linearity as 1 × 10(-3) to 10(3) μM and shelf life of about 10 weeks under refrigerated conditions. Attempts have been made to utilize this electrode for estimation of deferiprone in urine samples. The developed sensor exhibited high reproducibility and good storage stability.
