This paper reports on a method for self-patterned electroplating to selectively deposit gold on vertical surfaces of microfabricated silicon structures. This method was developed out of the effort to realize microfabricated multicapillary columns (μMCC) for chromatographic separation aimed for handheld chemical analysis. Results showed the successful selective vertical wall electroplating...
This paper reports the first microelectromechanical-systems (MEMS)-based stationary phase coating technique called monolayer-protected gold for ultranarrow single-capillary (SCC) and multicapillary (MCC) microfabricated gas chromatography (??GC) columns, yielding the highest separation performance reported to date. The conventional coating methods are mainly based on the solvent evaporation of a polymeric...
This paper reports, for the first time, a new phenomenon named self-patterned electroplating used to selectively deposit a thin gold layer on vertical sidewalls of high-aspect-ratio channels. The ability to cover only vertical surfaces of three dimensional (3D) structures is a significant achievement in microsystems technology serving a wide range of applications including gas chromatography (GC)...
This paper reports the first MEMS-based stationary phase coating technique for ultra-narrow single capillary (SCC) and multicapillary (MCC) microfabricated gas chromatography (muGC) columns yielding the highest separation performance reported to date. The conventional coating methods are mainly based on the solvent evaporation of a polymeric solution. These methods, which are developed for fused silica...
