Electrochemical and piezoelectric DNA biosensors for hybridisation detection

Analytica Chimica Acta, 2008
DNA biosensors (or genosensors) are analytical devices that result from the integration of a sequence-specific probe and a signal transducer. Among other techniques, electrochemical and piezoelectric methods have recently emerged as the most attractive due to their simplicity, low instrumentation costs, possibility for real-time and label-free ...

Electrochemical DNA Biosensors Based on DNA-Drug Interactions

Electroanalysis, 2002
The world of drug designing is ever changing. The investigations of drug-DNA interactions would provide new compounds to be tested for an effect on a biochemical target, and also to be used as promising hybridization indicators for the design of DNA biosensors, which will further become DNA microchip systems.

Electrochemical DNA biosensor for analysis of wastewater samples

Bioelectrochemistry, 2002
The application of a disposable electrochemical DNA biosensor to wastewater samples is reported. The DNA biosensor is assembled by immobilising double-stranded calf thymus DNA on the surface of a disposable, carbon screen-printed electrode (SPE).

Performance of interdigitated nanoelectrodes for electrochemical DNA biosensor

Ultramicroscopy, 2003
An electrochemical methodology for bio-molecule sensing using an array of well-defined nanostructures is presented. We describe the fabrication by e-beam lithography of nanoelectrodes consisting of a 100 micro m x 50 micro m area containing interdigitated electrodes of 100 nm in width and interelectrode distance of 200 nm. Sensitivity and response time

Electrochemical DNA biosensor for the study of ciprofloxacin–DNA interaction

Analytical Biochemistry, 2006
The interaction of ciprofloxacin with DNA was studied by using an electrochemical DNA biosensor. The binding mechanism of ciprofloxacin was elucidated by using constant current potentiometry and differential pulse voltammetry at DNA-modified glassy carbon electrode.

Carbon nanotube-enhanced electrochemical DNA biosensor for DNA hybridization detection

Analytical and Bioanalytical Chemistry, 2003
A novel and sensitive electrochemical DNA biosensor based on multi-walled carbon nanotubes functionalized with a carboxylic acid group (MWNTs-COOH) for covalent DNA immobilization and enhanced hybridization detection is described. The MWNTs-COOH-modified glassy carbon electrode (GCE) was fabricated and oligonucleotides with the 5'-amino group were ...
