The goal of this project is to design, build, and validate a more economic portable Fast Scan Cyclic Voltammetry (FSCV) device to measure the concentration of neurotransmitters like dopamine. The device will allow educational demonstrations in classrooms and allow researchers to gather data without the financial burden of a full cost system. The device is created on a Printed Circuit Board (PCB) that interfaces with a standard computer through MATLAB. This allows data collected on the PCB to be accessible to the user to display and analyze at will, all while maintaining the system’s portability and low cost. The device was tested using a dummy cell and artificial cerebral spinal fluid (ACSF), comparing the results to those obtained from the gold standard laboratory equipment for the same simulated experimental setup. Our device is able to show the main features that distinguish a voltammogram of the dummy cell and dopamine. Priced at about $200, which is $8,800 less than the gold standard equipment, our device demonstrates the feasibility of a useful low cost.
