    摘要: Techniques are provided for a microfluidic chip for performing a microfluidic reaction. The microfluidic chip includes a rigid layer, a first polymer layer that forms a first surface of a microfluidic chamber within the microfluidic chip, a first adhesive layer disposed between the rigid layer and the first polymer layer, and a second polymer layer that forms a second surface of the microfluidic chamber, and a first port connecting an exterior of the microfluidic chip to the microfluidic chamber through at least the rigid layer, the first polymer layer, and the first adhesive layer. A first self-sealing valve is formed in the first polymer layer and disposed within the first port, the first self-sealing valve configured to seal directly against the rigid layer through a first gap in the first adhesive layer in response to pressure from thermal expansion of a fluid within the microfluidic chamber.
