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.
