Forming submicron channels on surfaces with potential future applications in nanoelectronics, chemical analysis and micro-engineering, employs oscillatory Langmuir-Blodgett wetting technique

摘要

Production of arranged parallel-aligned organic channel structures utilizing dewetting steps is claimed in which differing material surfaces in the submicron region are capable of being modified in respect of their wetting characteristics. Preferred features: Macroscopic regions exceeding 1 micro m<2>, especially 1 mm<2> -1 cm<2>, are modified in terms of their wetting characteristics. For the process, a non-energetic procedure, e.g. Langmuir-Blodgett (a specific thin surface film-) technology is employed. Channel structures arising are formed by organic material and are up to 1 micron wide. They may be filled with further materials. Such filling is achieved as a result of capillary forces and/or thermal vapor deposition. In a further variant, electrophoretic methods are employed. Channel filling comprises especially metallic clusters and/or magnetic materials. The filling comprises biological materials.
