Sequential and parallel localoxidation nanolithographies have been applied to pattern pentacene samples by creating a variety of nanostructures. The sequential localoxidation process is performed with an atomic force microscope and requires the application of a sequence of voltage pulses of 36 V for 1 ms. The parallel localoxidation process is performed by using a conductive and patterned stamp. Then, a voltage pulse is applied between the stamp and the pentacenesurface. Patterns formed by arrays of parallel lines covering 1 mm2 regions and with a periodicity of less than 1 ?m have been generated in a few seconds. We also show that the patterns can be used as templates for the deposition of antibodies.

Abstract
Sequential and parallel localoxidation nanolithographies have been applied to pattern pentacene samples by creating a variety of nanostructures. The sequential localoxidation process is performed with an atomic force microscope and requires the application of a sequence of voltage pulses of 36 V for 1 ms. The parallel localoxidation process is performed by using a conductive and patterned stamp. Then, a voltage pulse is applied between the stamp and the pentacenesurface. Patterns formed by arrays of parallel lines covering 1 mm2 regions and with a periodicity of less than 1 ?m have been generated in a few seconds. We also show that the patterns can be used as templates for the deposition of antibodies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
