Electrochemical detection of peptides

Analytical Chemistry, 1989
A general method of wide applicability for the determination of peptides is described. Peptides longer than dipeptides react in the classical biuret reaction with Cu(II) to yield electroactive Cu(II)-peptide complexes that can be oxidized to the corresponding Cu(III) complexes.

Electrochemical immunosensor for the detection of atrazine

Journal of Molecular Recognition, 1998
An amperometric immunosensor for the detection of the herbicide atrazine has been developed. A redox polymer PVPOs(bpy)2Cl was co-immobilized with the specific antibody on the surface of the electrode by crosslinking with PEGDGE to form an electron-conducting hydrogel.

Electrochemical sensors for detection of biomolecules

2009 IEEE International Conference on Electro/Information Technology, 2009
A novel electrochemical sensor for detection of biomolecules was investigated. The sensor was fabricated using Micro Electro Mechanical System (MEMS) knowledge, and the sensor has the ability to transduce bimolecular signal directly into an electrical signal.

Optical and electrochemical detection of DNA

Biomaterials, 1988
There is a growing demand for the production of a DNA biosensor with applications in medicine, the food industry, agriculture, veterinary science and environmental science. In this paper we describe methods for the optical and electrochemical detection of DNA using the enzyme horseradish peroxidase (EC 1.11.1.7) and glucose oxidase (EC 1.1.3.4).

Electrochemical detection of carcinoembryonic antigen

Biosensors and Bioelectronics, 2018
In this work, a sandwich-type electrochemical immunosensor for carcinoembryonic antigen (CEA) detection has been constructed and tested. Unlike many other sensors using external electrochemical species in the electrolyte to generate an electrochemical signal, a ferrocene derivative has been integrated into the design of the sensor to provide an ...

Discrete microfluidics with electrochemical detection

The Analyst, 2007
A droplet-based electrochemical digital magnetofluidics system has been developed. The system relies on the magnetic movement, in air, of different aqueous microdroplets containing magnetic microparticles--serving as the 'sample', 'blank', 'wash' and 'reagent' solutions--into and out of a three-electrode assembly.

Electrochemical Detection of Lesions in DNA

Bioconjugate Chemistry, 2005
Electrochemical DNA-based sensors that exploit the inherent sensitivity of DNA-mediated charge transport (CT) to base pair stacking perturbations are capable of detecting base pair mismatches and some common base damage products. Here, using DNA-modified gold electrodes, monitoring the electrocatalytic reduction of DNA-bound methylene blue, we examine ...
