Microfilaria filtering microfluidic chip ? Preliminary study

This paper provides a preliminary experiment of microfluidic filtering chip, designed to be used in an area that lacks of laboratory equipment. Without blood preparation involved sophisticated machines, the blood sample was used without rinsing or hemorrhaging before feeding into the chip. This chip contained with a wedge shape zone and detectable zone, which was in a cylindrical shape. The tests were performed with different sizes of inlet and length of the chip. From experimental results, the 5-μm micro capillaries allowed blood to flow through and was be able to filter a larger substance inside. However, appropriate blood dilution-ratio and filtering efficiency are needed to be clarified in the further experiment.
