A microfluidic chip includes a base layer, a fluid layer, and a gas regulating layer. The base layer includes a microarray detecting zone. The microarray detecting zone includes a substrate, a photoresist pattern layer, a blocking layer, a bonding layer, at least one linker molecule, and a probe molecule. The bonding layer is covalently attached to the photoresist pattern layer. The at least one linker molecule is covalently bonded to the binding layer. The probe molecule is covalently bonded to the at least one linker molecule for specifically reacting with an under-test molecule. The fluid layer is disposed over the base layer, and includes plural flow channels for introducing or collecting detecting reagents. The gas regulating layer is disposed over the fluid layer for controlling open/close statuses of the flow channels, thereby controlling a flowing condition of a fluid in the fluid layer. |
