Xanthine biosensor based on XO/AuNP/PtNP/MWCNT hybrid nanocomposite modified GCPE

A new xanthine (X) biosensors based on a hybrid nanocomposite containing multi-walled carbon nanotubes (MWCNT), Pt nanoparticles (PtNP) and gold nanoparticle (AuNP) was presented. X biosensor was fabricated by dropping AuNP/PtNP/MWCNT onto xanthine oxidase (XO) modified glassy carbon paste electrode...

Summary:A new xanthine (X) biosensors based on a hybrid nanocomposite containing multi-walled carbon nanotubes (MWCNT), Pt nanoparticles (PtNP) and gold nanoparticle (AuNP) was presented. X biosensor was fabricated by dropping AuNP/PtNP/MWCNT onto xanthine oxidase (XO) modified glassy carbon paste electrode (GCPE). Resulted XO/AuNP/PtNP/MWCNT/GCPE biosensor showed two linearity between 2.0 and 50 µM and 0.25 and 6.0 mM for X. RSD value was calculated as 2.46 (n = 5). Finally, the biosensor was applied to the X detection in synthetic serum samples and good recovery value was obtained.
