DNA electrochemical biosensors
Fresenius' Journal of Analytical Chemistry, 2001Disposable electrochemical DNA-based biosensors are reviewed; they have been used for the determination of low-molecular weight compounds with affinity for nucleic acids and for the detection of the hybridisation reaction. The first application is related to the molecular interaction between surface-linked DNA and the target pollutants or drugs, in ...

Electrochemical biosensors for DNA hybridization and DNA damage
Biosensors and Bioelectronics, 1998Recent trends in the development of DNA biosensors for nucleotide sequence-specific DNA hybridization and for the detection of the DNA damage are briefly reviewed. Changes in the redox signals of base residues in DNA immobilized at the surface of carbon or mercury electrodes can be used as a sign of the damage of DNA bases.

Disposable Electrochemical DNA Biosensors
2004Electrochemical DNA hybridization biosensors have been a major research field for over a decade, because their rapid, simple, and low-cost detection capabilities provide several advantages to clinical, forensic, and environmental monitoring. Basically, DNA biosensors convert the Watson-Crick base-pair recognition event into a readable analytical signal.
