ssdna-immobilized
1.The hybridization reaction was conducted by immersing the ssDNA-immobilized electrode in FCA-DNA probe solution.
2.Single-stranded DNA (ssDNA) could be immobilized covalently on the surface of SA/CPE to fabricate ssDNA modified electrode (ssDNA/SA/CPE) in the presence of 1-Ethyl-3-(3-dimethyl-aminopropyl)ca-rbodiimide(EDC) and N-Hydroxyosuccinimide(NHS).
3.ssDNA or dsDNA could be immobilized covalently on the surface of OA/CPE to fabricate ssDNA/OA/CPE or dsDNA/OA/CPE in the presence of EDC.
