Method Development for Electrochemical Impedance Spectroscopy Studies of Bovine Serum Albumin on Platinum Electrode Surfaces

MacDonald, Michelle 24 March 2014 (has links)
In this thesis, a method is presented for studying protein adsorption on solid surfaces by Electrochemical Impedance Spectroscopy (EIS), using a model system of Bovine Serum Albumin (BSA) on platinum electrode surfaces. EIS is a commonly used analytical technique for electrochemical biosensors, particularly useful because of the ability to model the electrochemical data with Equivalent Electrical Circuits (EECs) and extract meaningful quantitative values for physical processes that are occurring in the electrochemical system (for example, double-layer capacitance Cdl or charge-transfer resistance Rct). In this thesis, a comprehensive method for EEC selection is developed by which the data are found to be Kramers-Kronig compliant, a library of possible circuits is selected, and then residual errors, parameter values, and standard deviations based on replicate measurements are used to find the circuit which best models the electrochemical system. The influence of number of factors related to experimental set-up and EIS conditions on BSA adsorption is examined, and suggestions are given as to avoid signal convolution by these factors. Most influentially, performing EIS in Phosphate Buffered Saline (PBS) before exposure to BSA results in a significant decrease in BSA film formation. BSA adsorption is strongly influenced by potential, with more positive potentials resulting in greater BSA adsorption. The application of ac vs. dc potential, however, does not influence the BSA film. Surface-Enhanced Raman Spectroscopy (SERS) experiments of BSA and Human Serum Albumin (HSA) adsorption on gold Sphere Segment Void (SSV) substrates are also presented. Finally, BSA adsorption on platinum surfaces is monitored over time using EIS. Results suggest that, after incubation, BSA desorbs from the electrode surface but the rate of desorption is dependent on the concentration gradient between the surface and the bulk solution. Results also suggest that BSA adsorption is strongly affected by concentration, with higher concentrations resulting in greater BSA adsorption on the electrode surface and greater BSA desorption upon change to a less positive potential.
