  • Publication number: 20100056394
    Abstract: The present invention discloses a bio-reaction module, the so called mini bio-reactor, for providing a stable environment for the hybridization or immuno-reaction on biochips with constant temperature and humidity. Moreover, the mini bio-reactor can be a tool for studying the bio-reaction mechanism. Any variations in bio-reaction mechanism and environmental factors may affect experiment outcomes. Hence, when bulky equipment is miniaturized into a module system, the researchers can utilize a mini bio-reactor to perform bio-experiments or reactors in series connection to perform batch experiments. The structure design of mini reactor is able to promote better reaction efficiency and to shorten reaction time for a variety of bio experiments. Hence what is developed is an automatic, handy and inexpensive device for bio researches with high sensitivity and reliability.

  • Publication number: 20090010767
    Abstract: An electric comb driven micropump system includes a piston, a comb actuator comb and a real-time monitoring device. The comb actuator may generate an electrostatic force after receiving a voltage, so as to actuate the piston to make a first displacement, which causes a fluid to enter into a cavity, wherein the voltage has a voltage value for determining the volume of the fluid entering into the cavity, and wherein as the voltage value of the voltage gradually decreases, the electrostatic forces also decreases, allowing the piston to gradually make a second displacement in a direction opposite to the first displacement driven by a spring, thus outputting the fluid from the cavity. The real-time monitoring device provides real-time information of the comb actuator.

  • Publication number: 20060280629
    Abstract: The present invention provides a loop-type microfluidic system, and the microfluid therein could be driven to move around the loop-channel repeatedly by the air comes from the air holes and through the driving conduits. In order to process the polymerase chain reaction (PCR), the microfluid should bear the temperature changes for three times. Hence, plural temperature controllers are utilized to adjust the temperatures of the sections constituting the loop-channel. Moreover, the times of cycles may be determined based on the desired times of reactions. The present invention could also increase or decrease the number of the air holes, the driving conduits and the temperature controllers to adjust the times of temperature changes according to the demands of various biochemical reactions.
