"very short pulse of red laser light to use fullerene to switch path of incoming electron... witching speed 1 million times faster (3 to 6 orders magnitude) than computers with electronic transistors... unprecedented levels resolution in microscopic imaging devices... fullerene switch allows resolutions around 300 pm... a single molecule enables increase in complexity of system without increasing its physical size"
