Abstract:Disposable microfluidic chips are becoming increasingly important for biological and chemical researches. Future advances in their commercial applications depends on the mass fabrication of low cost microfluidic chip. In this study we are presenting a simple, low cost and fast way of fabricating PMMA microfluidic chips based on laser erosion. The influence of the width and depth of PMMA microchannels on erosion current and erosion times was analyzed. To bond the open PMMA microchannels at low pressure and temperature, sticky tape assist bonding method was proposed. By this method, the microfluidic chip can be fully sealed without using any equipment. The leakage test indicated that the bonded microfluidic chip can endure an pressure up to 0.82 MPa.
