Advancement in electrochemical DNA-biosensors for GMOs detection: A review

Genetically modified organisms (GMOs) are plants or animals whose genetic make-up has been transformed by recombinant DNA technology, which has new features such as resistance to herbicides, virus and insect. Recently, genetic modification of food products has increased in order to reduce world poverty and hunger and increase food production However, the impact of GMOs on the human health is a ...

An Electrochemical Study of Hemoglobin

In the course of a series of investigations on the physical chemistry of hemoglobin now being carried on in the Laboratory of Physical Chemistry of the Harvard Medical School, Dr. E. J. Cohn and Dr. R. M. Ferry discovered certain abnormalities in the behavior of a hydrogen electrode immersed in solutions of hemoglobin and oxyhemoglobin. On studying the matter further they found that any inert e...

Electroanalysis of the Herbicide Diquat by Electrochemical Detector Containing Particles of Clay in Environmental Water

Clay modified carbon paste electrode (CPE-C) its applicability for electroanalysis of N, N’-ethylene-2,2’-bipyridinium (diquat) has been described in the present work. Electrochemical modification was performed by electronic impedance spectroscopy (EIS) and cyclic voltammetry (CV) in the range of -0.6 V to 1.2 V in 0.1 M K2SO4 (pH 3). The voltammetric method behavior of DQ is suggested where an...
