A modified atomic force microscope is used to perform contact resistance andor current-dependent stiction measurements for conductive thin films at controlled values of applied force. The present method comprises the steps of isolating primordial germ cells from an avian embryonic gonad; and culturing said PGCs in vitro for at least 5 days. A designer need not publish the design before seeing how it will actually look because the design interface determines and then uses publishable HTML code to present the design, even in real time.
