A microfluidic chip with a built-in gravity-driven micropump is provided. The gravity-driven micropump comprises a winding channel, an inert fluidic material placed inside the winding channel, and a suction channel that links the winding channel to the microfluidic chip. The winding channel is for the inert fluidic material to flow in. A fixed volume of high density, inert fluidic material is placed in the winding channel to act as a micropump in the bio chip. When the microfluidic chip is placed in a declining or standing position, the inert fluidic material flows along the winding channel due to the gravity. The invention provides a simple, convenient, and robust microfluid pumping source. With the built-in micropump, this invention is free-of-pollution and saves the manufacturing cost for the pipe link between the bio chip and peripheral devices.

An apparatus and a method for collecting fluid fractions. The present apparatus includes an inlet, a channel, a plurality of collectors, and an outlet. The inlet communicates with the collectors and the outlet through the channel. The collectors are disposed between the inlet and the outlet. The method for collecting the fluid fractions comprises two steps. First step, injecting the fluid in to the inlet for guiding the fluid to the outlet along the channel, wherein the fluid fills the collectors one by one due to the capillary attraction when passing through the collectors, and flows to the outlet after the collectors having been filled. Second step, injecting pressurized gas into the channel to drain the fluid fractions from fill the collectors respectively to a plurality of corresponding containers.

This specification disclosed a partially closed microfluidic system and a fluid driving method. The microfluidic system is comprised of a substrate with microfluidic elements and a thin film. A feature of this structure is that the thin film is elastic and deformable. It has a single opening corresponding to a vent hole on the substrate, thus forming a partially closed microfluidic system. The substrate is designed to have several positions for micro fluid elements and deformable chambers and uses micro channels to form a complete network. Since the thin film is elastic and deformable, one is able to impose a pressure on the thin film above the deformable chambers in this partially closed microfluidic system to drive the fluid into motion. Once the pressure is released, the fluid flows back to its original configuration.

A method for thermal control of microfluid and a device using the thermal control method utilizes a chip provided with a microchannel and a pneumatic microflow driving element to drive a microfluid back and forth in the microchannel at a predetermined frequency. Heating devices are arranged along specific sections of the microchannel. By controlling the frequency of the back-and-forth movement of the microfluid, the temperature of the microfluid may be accurately controlled. Due to the rapid movement of the microfluid in the microchannel, uniform distribution of the temperature and ingredients in the microfluid may also be obtained.
