Abstract
A microfluidic device allowing for multiple discrete reactions sites and allowing for sequential reactions and sample analysis along with methods for device fabrication and use is provided. The microfluidic device provides a micro-total analysis system on a single substrate and has multiple reaction sites allowing for cascade reactions and analysis on a single chip using micro-quantities of sample and reagents. The microfluidic device provides discrete sites for immobilization of cognitive agents including enzymes, binding proteins, nucleic acids and the like as well as methods for quantitative analysis. The invention also provides methods for the fabrication of the device.
