Abstract:Traditional techniques to manufacture micro-fluidic devices are well established but most are limited to surface micro-fabrication. Laser micro-machining provides an alternative technique for micro-fabrication of devices. This paper presents the fabrication of 3-D micro-channel structures with four different types of glass, soda-lime, fused-silica, borosilicate and quartz. Results showed that quartz and fused-silica glasses provided better channel topologies for chemical sensing applications.
