Microfluidic Chips

The benefits of the microfluidic system are inherently scale reduction compared to the analytical method, simplicity in function and fabrication, rapid turnaround time, and decreased reagent consumption per test for DNA extraction and amplification. The reduced size of microfluidic chips not only enhances amplification speed but also provides dozens of reductions in PCR volume. Consuming less Taq polymerase has the potential to decrease the cost per test dramatically. Concordantly, the decrease in the number of reagents reduces the hazardous waste that must be disposed of and eliminates possible contamination and error during the extra experimental steps. Furthermore, the system could also display the integration of many microfluidic reactions, from DNA extraction to multiple downstream processes (PCR and electrophoretic analysis), on the same microdevice.
