Biochip, biological sample detection apparatus, and a method for detecting biological samples

Abstract

A biological chip, comprising a chip unit and an elastic pad disposed on the chip unit. The chip unit includes an upper substrate and a lower substrate, with a plurality of liquid inlet ports spaced apart from each other. A gap is formed between the upper substrate and the lower substrate to accommodate a detection liquid, with the liquid inlet ports formed in the upper substrate and communicating with the gap. The elastic pad includes a plurality of injection ports and a plurality of suction ports, arranged with spacing through the pad. The injection ports correspond to the liquid inlet ports. The suction ports correspond to the upper substrate and provide an adsorptive force to the upper substrate, thereby maintaining the height of the gap and preventing deformation of the biological chip, which could affect detection accuracy. The invention also provides a biological sample detection apparatus comprising the biological chip, as well as a method for detecting biological samples using the biological sample detection apparatus.
