Laser processing of microfluidic components and bioMEMS

Micro-processing with lasers is an enabling technology for microfluidics and bioMEMS due to the high precision, accuracy and resolution achievable using laser sources. Visible micromachining of metals and ceramics has proved an efficient and precise way of producing spotting pins for high-throughput screening applications. UV micromachining of the polymer materials often used in metered dose inhalers (MDI) and other medical devices is efficient due to the high absorption properties of these polymers. Key to these types of devices is the accuracy and reproducibility. This paper describes the use of copper vapour lasers to produce micro-fluidic and bioMEMS type components.
