Abstract
In recent years, Electrochemical Impedance Spectroscopy (EIS) has received special attention of the researchers due to its suitability for sensing/analysis of the cells and the biological molecules in a label-free manner. The current study proposes the fabrication of thin-film aluminium electrodes on a glass substrate by thermal evaporation method. The electrodes were fabricated having gaps of varied lengths. Different electrical models were used to determine the electrical stability of the system using an in-lab developed LabVIEW program. The electrode having the best stability was used for EIS analysis of distilled water and saline solutions of different strengths to validate its proper functioning.
