METHOD FOR MANIPULATING FLUID TO REDUCE WORKING FLUID DILUTION IN LIQUID SYSTEM AND SYSTEM THEREFOR

摘要

PURPOSE: A method for manipulating a fluid and a system therefor are provided to result in less, or preferably no contamination or undesired dilution of the fluid. CONSTITUTION: The method for manipulating, especially transporting a desired fluid in a channel comprises the steps of: providing a working fluid for transporting the desired fluid; providing a first segment of a first buffer fluid immiscible with the working fluid and the desired fluid; providing a first segment of the desired fluid; providing a second segment of a second buffer fluid immiscible with the working fluid and the desired fluid; and providing the desired fluid to be transported and further manipulated. The microfluidic handling system comprises a microsystem platform which includes a substrate having a first plane with at least one microchannel for manipulating a desired fluid and a second plane opposite to the first surface.
