Description

The surface structure of an artificial membrane composed of a Millipore filter and a synthetic lipid analogue, dioleylphosphate (DOPH), immersed in KCl solution changes from a highly reflective hydrophilic state to a poorly reflective hydrophobic state by increase of calcium ion concentration in KCl solution. Using a microscopic digital image processing system the structural changes can be estimated quantitatively, such as a histogram of the brightness level and a binary black-and-white picture. The gross area of hydrophilic domains and the mean diameter of hydrophilic particles were measured by processing a binary picture
