Integrated semiconductor microreactor for real-time monitoring of biological reactions

摘要

An integrated semiconductor chemical microreactor for real-time polymerase chain reaction (PCR) monitoring, has a monolithic body of semiconductor material; a number of buried channels formed in the monolithic body; an inlet trench and an outlet trench for each buried channel; and a monitoring trench for each buried channel, extending between the inlet and outlet trenches thereof from the top surface of the monolithic body to the respective buried channel. Real-time PCR monitoring is carried out by channeling light beams into the buried channels, possibly through one of the inlet or outlet trenches, whereby the light beams impinge on the fluid therein and collecting the emergent light coming out from the monitoring trench.
