文摘
- •
Water soluble HRP and Toluidine blue were covalently immobilized in sol-gel matrix.
- •
Leak-free renewable ceramic composite biosensor has been fabricated.
- •
The biosensor successfully analysed H2O2 at a low potential of − 0.25 V (vs SCE).
- •
The biosensor exhibited good long-term stability and surface renewability.
