Printing via Photolithography on Micropartitioned Fluid Lipid Membranes

A four-level grayscale image of Abraham Lincoln on a lipid bilayer membrane(see Figure) is used to demonstrate this novel single-exposure photolithographic procedure for printing images on fluid surfaces containing partitioned corrals, the very nature of the fluid membrane allowing true grayscale to be achieved. The potential scope and applications—particularly in biotechnology—of the concept are also discussed.
