2.2. Manipulation of liquid drop on tilt sheet
Fig. 1 illustrates the setup of the instrument. An acrylic sheet is attached with Teflon tape that becomes platform of the system. This could be fabricated by using easily available and low cost materials. The hydrophobic surface of Teflon tape provides the high contact angle of aqueous liquid drop on surface, while the glass auxiliary electrode provides the good hydrophilic surface for aqueous liquid drop.
