文摘
- •
Gr/TiO2 nanocomposites were used as electrode material in amperometric hypoxanthine sensors for meat freshness evaluation.
- •
The Gr/TiO2 nanocomposite offered a favorable microenvironment for direct electrochemistry of xanthine oxidase (XOD).
- •
The fabricated sensor exhibited excellent electro catalytic activity towards hypoxanthine.
- •
Sensor measurements revealed good correlation to measurements obtained by enzymatic colorimetric method (r=0.9795).
