This paper overviews research being conducted at the Industrial Research Institute Swinburne (IRIS). This research project commenced in August 2001, with funding provided by the Cooperative Research Centre (CRC) for Microtechnology. The goal and purpose of this project is to develop novel sealing techniques for polymerbased microfluidic devices. The main challenge is bonding planar microfluidic parts together hermetically without affecting the shape and size of micro-sized channels. In this paper a number of bonding techniques such as induction heating will be reported; and their advantages will be discussed. Also, progress to date and future work will be presented. The channels were fabricated by using Excimer laser equipment.
