Nano Electrochemistry counts the Blood

-



The Scientists at the University of Oxford, UK develop accessible, painless technology as deemed for the development of modern technology. This electrochemical technique replaces the time-consuming Optical Microscope, simplifies the complex instrumentation techniques, and is proved to be an economical technique.
The electrochemical instrument required to carry out an electrochemical analysis is an electrode and commercial electrochemical device. Diluted 5 µL of blood placed on biocompatible graphite electrode and voltammograms are obtained. Reduction in the amount of oxygen present in the pure buffer solution results in a slight electrochemical signal at the electrode. Blood samples give a higher intensity signal because of their oxygen content. This electrochemical signal generated gives an estimate of the erythrocyte concentration precisely.
This signal strength can further be increased by the addition of Hydrogen peroxide which breaks down into oxygen and water by the enzymes glutathione peroxidase. This time the carbon microelectrode was replaced by graphite electrode the current was recorded keeping the voltage as a constant. This measurement resulted in spikes with an increase in the erythrocyte concentration.
Have a Nano Electrochemical research work to be published?? The arena is all yours at Materials Electrochemistry 2018.

Salmonella a rod shaped bacteria with a length of ~2 to 5 µm and a width of ~ 0.7 to 1.5 µm well-known for being a typhoid agent. The serotype  Salmonella  typhi  which is the causative agent for typhoid while other non-typhoid serotypes like   Salmonella typhimurium  and  Salmonella enteritids usually cause diarrhoea and abdominal pains from which the healthy individuals seem to recover whereas a sub-Saharan Africa outbreak of these non-typhoid serotypes has resulted in a mortality rate estimated at 20 – 25 %. The origin of the causative agent consumed may be different and people can be infected by food contaminated with faeces. The food can get contaminated during the butchering process, seafood sourced from contaminated water, infected chickens laying contaminated eggs, and fresh fruit and vegetables being washed with unclean water. Even though the foods contaminated by Salmonella look and smell normal the monitoring needs to be highly sensi...
