Abstract :
A microfluidic chip which has the potential to rapidly detect malaria by detecting fluorescence-labelled parasites in red blood cells is proposed. The heart of this system is the electrokinetic manipulation of fluid to transport cells in microchannel. In this paper, the use of Micro Particle Image Velocimetry to characterise the electroosmotic flow in PDMS microchannel is reported. The effect of pressure-driven backflow is discussed and modifications of channel design to enhance pressure resistance were proposed and experimentally verified.
