  1. In this work we investigate the electrical properties of phospholipid bilayer membranes (LBMs) formed from phosphatidylserine by analyzing two experimental setups. The Electrochemical Impedance Spectra (EIS) of phosphatidylserine show that a lipid bilayer membrane formed from this phospholipid has an average specific electrical resistance of 3.466 k Ω.cm 2 and an average capacitance of 0.385 µF/cm 2 . Some of the major factors that affect the LBM resistance include electroporation, the method of deposition, and the surface tension in microchannels for supported LBMs. Therefore, wide apertures remain the most accurate method for supporting LBMs.

    Contact angle measurement is a commonly used technique to measure the wettability of a solid surface The technique is highly susceptible to error when conducted by a human operator In this project, the experiment is robotized to increase accuracy, in which the Denso COBOTTA robot is used to dispense pure liquid drops onto a variety of surfaces in order to measure the contact angle for each surface. The experiment is currently being expanded for robotized deposition of lipid bilayer membranes.
