Development of Carbon Nanostructured Based Electrochemical Sensors for Pharmaceutical Analysis

Pharmaceutical drugs play an important role in human life since they caused a revolution in human health. Notably, their administration to a living organism helps body to stay healthy. Commonly, they are employed to diagnose, prevent, or treat and cure a disease via a biological effect on a human body. Administration of impurity-free and adequate amounts of pharmaceutical compounds would be beneficial. Therefore, the quantity and purity of the substances in pharmaceutical compounds are continuously monitored during drug manufacturing with various chemical or instrumental analysis techniques. The possibility of impurities development and chemical or quantity changes of active drug species at various stages (namely during production, transportation or storage) makes them redundant and risky for human health. So, sensitive and accurate analysis methods for qualitative and quantitative analysis are highly demanded by pharmaceutical companies and medical centers. The present mini review emphasizes on application of carbon based modified electrodes in health care and pharmaceutical analysis. Electrochemical determination of drugs employing carbon nanostructured modified electrodes will be reviewed and their advantages and disadvantages will be mentioned.
