摘要: A method of analyzing a sample fluid containing organic microobjects is proposed. The method comprises the steps of: up-concentrating (S1) the microobjects by removing, in a total time T1, a volume V1 of the sample fluid from the upconcentrate sample microobjects; immersing (S2) the microobjects in a transfer fluid, or leaving the microobjects in a remaining portion of the sample fluid, the remaining portion of the sample fluid then providing the transfer fluid; filtering (S3), in a total time T3, a volume V3 of the transfer fluid by a filter, thereby accumulating the microobjects on the filter; and generating (S4) an image of the microobjects accumulated on the filter; wherein the throughput V1/T1 of the step of up-concentrating (S1) is greater than the throughput V1/T1, of the step of filtering (S3). The filter may be a second filter, and the step of up-concentrating (S1) may involve: filtering the sample fluid by a first filter, thereby accumulating the microobjects on the first filter. An apparatus or system for analyzing a sample fluid containing organic microobjects is also disclosed.

摘要: The invention relates to an electrowetting-on-dielectric device (200). This is an electro wetting device comprising one or more cells, wherein each cell comprises an electrowetting composition of first and second immiscible fluids, the first fluid being an electrolytic solution (240), a first electrode (230), separated from the electrowetting composition by a dielectric (231), and a voltage source (260) for applying an operating voltage difference between the first electrode (230) and the electrolytic solution to operate the electrowetting device. According to the invention, the first electrode (230) of the electrowetting-on-dielectric device (200) comprises a valve metal, and the electrolytic solution (240) is capable of anodizing the valve metal to form a metal oxide at the operating voltage difference. This provides the electrowetting-on-dielectric device (200) with self-repairing properties thereby preventing breakdown of the dielectric. As a result, the electrowetting device can be operated at a low voltage, and it has an improved reliability.
