Integration of a complete diagnostic lab onto a credit-card sized chip requires micro-channels to handle small volumes of fluids. Initially silicon chip technology was used to create microfluidic devices, but that posed some process limitations with respect to cost and cycle times. Another technique frequently used is soft lithography.  However, this method has some limitations on the device design and manufacturing.  More advanced technologies use injection molding to fabricate two or more separate parts that require post molding operations.  These parts are then stacked and sealed to each other, making the device fit for service. In other applications, the injection molded part containing the microfluidics channels is sealed off by applying tapes on the half open channels. SABIC is currently researching whether hesitation, which is an unwanted effect resulting in typical injection molding defects, can be used to create structures with closed and sealed micro channels under the surface. This method of chip production may increase production speed since secondary operations such as positioning, sealing, clamping or welding, are no longer required.
