文摘
- •
A heated gold particles modified gold disk electrode (Au-HAuDE) was fabricated.
- •
HRP-DNAzyme as signal label for DNA detection at Au-HAuDE was realized.
- •
With elevated electrode temperature, the detection limit was greatly improved.
- •
This method can easily be extended to other biological molecule measurements.
