Voltammetric Sensors for the Determination of Pharmaceuticals

Electrochemical sensors are increasingly being investigated to perform measurements for single or multiple analytes. Demanded by modern medical diagnosis, advances in microfabrication technology have led to the development of fast, sensitive and selective electrochemical sensors for drug analysis. Electrochemical sensors for the measurement of analytes of interest in clinical chemistry are ideally suited for these applications, due to their high sensitivity and selectivity, simple-to-operate, rapid response time and low-cost. As part of the present investigations eight voltammetric sensors have been fabricated for six drugs such as PAM Chloride, Tamsulosin Hydrochloride, Hesperidin Methyl Chalcone, Guaiphenesin, Cephalexin and Amoxicillin trihydrate. The modification techniques adopted as part of the present work include multiwalled carbon nanotube (MWNT) based modifications, electropolymerization, gold nanoparticle (AuNP) based modifications and platinum nanoparticle (PtNP) based modifications.
