We develop a facile method to immobilize cucurbituril on silicon substrates through photochemical reaction with azido groups. Combining photolithography and the competitive molecular recognition between CB[7] and acridine orange base or 1-adamantanecarboxylic acid, a patterned surface with reversible fluorescence emission can be obtained.
The major steps in the pattern transfer process will be identified and used to explain the individual aspects of the challenges involved with high aspect ratio and high topography. The structural perspective of micromachined devices will then be introduced as a foundation for identifying the high aspect ratio and high topography challenges. These two key photolithography challenges will then be...
This report discusses the method for the fabrication of microchannels. Microchannel production is a two step process. First, soft photolithography methods are implemented to fabricate a reusable mold. The mold is then used to create the microchannel, which consists of polydimethylsiloxane, or PDMS, and glass. Bio-related applications are also discussed.
We report the demonstration of a reflection microscope that operates at 13.2 nm wavelength with a spatial resolution of 55+/-3 nm. The microscope uses illumination from a tabletop extreme ultraviolet laser to acquire aerial images of photolithography masks with a 20 s exposure time. The modulation transfer function of the optical system was characterized.
This paper reports a rapid microchip-based electrochemical enzyme immunoassay with surface-functionalized poly(dimethylsiloxane) (PDMS) channel. The microchip fabricated on a glass substrate by photolithography consists of a three-electrode system for electrochemical detection and is assembled with the antibody-immobilized PDMS channel by plasma treatment. For effective immobilization of target...
