Fast assembly of non-thiolated DNA on gold surface at lower pH
(2013-12-01)
In a typical protocol for attaching DNA to a gold electrode, thiolated DNA is incubated with the electrode at neutral pH overnight. Here we report fast adsorption of non-thiolated DNA oligomers on gold electrodes at acidic ...

The importance of the assembling of DNA strands on the performance of electrochemical genosensors
(2020-12-01)
Electrochemical biosensors have been extensively studied due to their capacity for rapid and accurate detection of a wide variety of target molecules or biomarkers. Impedimetric DNA hybridization sensors are based on ...
Investigations of the antioxidant properties of plant extracts using a DNA-electrochemical biosensor

Application of Factorial Design Experiments to the Development of a Disposable Amperometric DNA Biosensor
(Wiley-v C H Verlag Gmbh, 2011-11-01)
The development of an amperometric DNA-based biosensor (genosensor) requires the optimization of many experimental parameters in order to maximize sensitivity. If only one parameter is evaluated per experiment, the resultant ...

DNA Biosensor Based on Double-Layer Discharge for the Detection of HPV Type 16
(MDPI, 2019-09)
DNA electrochemical biosensors represent a feasible alternative for the diagnosis of different pathologies. In this work, the development of an electrochemical method for Human Papillomavirus-16 (HPV-16) sensing is reported ...
Immobilization of streptavidin in sol-gel films: Application on the diagnosis of hepatitis C virus
(Elsevier B.V., 2006-10-15)
Recent advances have accelerated the development of biosensors for the analysis of specific gene sequences. In this kind of biosensor, a DNA probe is immobilized on a transducer and the hybridization with the target DNA ...

Piezoelectric biosensors for real-time monitoring of hybridization and detection of hepatitis C virus
(Elsevier B.V., 2004-05-01)
The piezoelectric quartz crystal resonators modified with oligonucleotide probes were used for detection of hepatitis C virus (HCV) in serum. The gold electrodes on either rough or smooth surface crystals were modified ...
