Temperature-adjustable biochip assembly

A temperature-adjustable biochip assembly, comprising:

• a biochip having a first binding hole, a second binding hole, a third binding hole, and a microfluidic channel embedded inside, wherein the microfluidic channel comprises a main microfluidic channel and a sub microfluidic channel, the main microfluidic channel has a starting end and a terminal end, the sub microfluidic channel intersects the main microfluidic channel at an intermediate point between the starting and terminal ends, the first binding hole leads to the starting end of the main microfluidic channel, the second binding hole leads to the sub microfluidic channel, and the third binding hole leads to the terminal end of the main microfluidic channel;
• and
• a temperature-controlling unit including a substance sited at a surface of the biochip, a cyclic guiding module passing through the substance, and a fluid flowed inside the cyclic guiding module, with the cyclic guiding module having a fluidic installed in the substance for guiding the fluid and a temperature-controlling component for modulating the temperature of fluid.
