This paper aims is reporting on a novel type of lithography based on thin stimuli responsive polymer films. The basic concept is the permanent storage of a pattern, which is reversibly developed and erased upon exposure to appropriate environments, e.g. solvent, pH and temperature. This technique is promising for the design of smart sensors and nanodevices, and in microfluidic technologies. The general concept of this novel type of environment-responsive lithography will be presented and discussed.
