Abstract: Methods for patterning highly sensitive materials, such as organic materials, organic semiconductors, biomolecular materials, and the like, with photolithographic resolution are disclosed. In some embodiments, a germanium mask (304) is formed on the surface of the sensitive material (302), thereby protecting it from subsequent processes that employ harsh chemicals that would otherwise destroy the sensitive material (302). A microlithography mask (306) is patterned on the germanium mask layer (304), after which the germanium exposed by the microlithography mask (306) is removed by dissolving it in water. After transferring the pattern of the germanium mask (304) into the sensitive material (302), the germanium and microlithography masks (304, 306) are completely removed by immersing the substrate in water, which dissolves the remaining germanium and lifts off the microlithography mask material.

Abstract: Nanowires are constructed using a variety of methods. Using one such method, a nanowire material is introduced to a microtubule lumen as a solution. The nanowire material is solidified to form a nanowire substantially within the microtubule lumen.

Abstract: An electronically tuned, wavelength-dependent optical detector is provided. The electronically tuned, wavelength-dependent optical detector is a modified metal-semiconductor-metal photodetector including a comb-like metal electrode at a common voltage and metal electrodes each supplied with a control voltage by a voltage means. The wavelength to be detected in an optical input illuminating the detector is selected based on the set of control voltages applied to the metal electrodes. In another embodiment of the invention, the wavelength to be detected with the electronically tuned, wavelength-dependent optical detector is also selected using a standing wave generator, such as an interferometer, to produce a spatially varying light intensity on the surface of the electronically tuned, wavelength-dependent optical detector. Electronic wavelength demultiplexing is also provided.

Abstract: A scanning optical microscope which includes an optical fiber which serves as a point source of light and for collecting reflected light is disclosed. A lens for focusing the light from the optical fiber onto an image plane and for gathering light reflected from the image plane and focusing it into the optical fiber is also disclosed, together with a scanning mechanism for scanning the light to scan a field of view.
