A microfluidic system for integration on lab-on-a-chip devices

Abstract

One of the main potentialities of a Lab-on-a-chip is the control of the processes in chemical analyses and the accomplishment of biochemical experiences, with application in medicine and biotechnology. The integration of microfluidic biochip in mass production is one of the objectives of this work. Unlike other cases of microfuidic systems which microchannels layout are a "serpentine", the proposed one has the particularity that the microchannels have a layout similar to “ladders”. The main advantage associated to this solution is that it can be obtained a complete mixing or reaction with smaller channels lengths, smaller sample volumes, short response times and with a fabrication cost reduction. Moreover, it can be easily integrated in Lab-on-a-chip device.
