An inkjet dispensing apparatus. The inkjet dispensing apparatus includes a cartridge, a chip, and a sensor controller. The cartridge includes a first channel and a second channel. The first channel has a first kind of liquid therein, and the second channel has a second kind of liquid therein. The chip is disposed on the cartridge, and includes a first conductor and a second conductor. The first conductor is in contact with the first kind of liquid, and the second conductor is in contact with the second kind of liquid. The sensor controller is coupled to the first conductor and the second conductor to detect leakage between the first channel and the second channel.

The matrix biochip sensing system of this invention uses a low-cost LED (light emit diode) matrix as the light source for the sensing system. The matrix biochip sensing system comprises an LED matrix light source, a biochip clamping member, an optical information filter module, an optical lens array, an optical sensor and a signal processing and control module. The light spots of the LED matrix is turned on in sequence, such that the fluorescent spots of the biochip that are respectively corresponding to the light spots of the laser diodes matrix may be actuated in the same sequence. Fluorescent spots so actuated are focused to a single optical sensor through an optical lens. At each sensing cycle of the optical sensor, only one fluorescent spot may be actuated. The output of the optical sensor in combination of the time axis may be processed by the signal processing and control module to obtain the genetic signals of the biochip.

A pneumatic apparatus and method for driving a microflow is disclosed. The microflow driving apparatus of this invention comprises an external pneumatic driving device that generates an array of airflows; an air gallery to accept airflows of said pneumatic driving device and to generate a suction force and an exclusion force; and a fluid channel connected with said air gallery to allow a fluid to flow inside it. In the air gallery, a trapezoid block is provided to generate an air circle from at least one of said airflows. An open gap is provided in the fluid channel at the connection of the air gallery and the fluid channel. When different combinations of airflows are introduced into the air gallery, a suction force or an exclusion force is generated to drive the reaction fluid inside the fluid channel to proceed, retreat or pause. A method using the apparatus for driving a microflow is also disclosed.
