Novel chemical sensors for some ionic species based on Nanocomposite polymeric membranes

Abstract

Electrochemistry has many features making it a unique technique for choice when analyzing real sample. Electrochemical techniques have the advantages of low cost, instrumental simplicity and portability in addition to high sensitivity and selectivity as well as wide linear range with low detection limits. This makes electroanalytical techniques among the most favorable analytical methods for different applications.

In particular, voltammetric sensors are an important category of electrochemical sensors. This thesis describes the development and electrochemical characterization and analytical applications of two voltammetric sensors developed for dopamine (DA) and glucose detection. Nickel nanoparticles (Ni-NP) based sensors and nickel-copper nanoparticles (Ni/CuNPs) based sensors were developed for the selective detection of dopamine and glucose, respectively.
