  • Microfluidic chips for rapid multiplex ELISA
    Patent number: 8075854
    Abstract: A microfluidic chip comprises a substrate and a channel or multiple channels in the substrate. Each channel includes a tortuous path section or multiple tortuous path sections. A receptor for the detection of an analyte can be immobilized in a tortuous path section, for example by adsorption. Different receptors can be immobilized in different tortuous path sections of each channel or in different channels for simultaneous detection of multiple analytes. The chip is especially useful for running immunoassays, particularly ELISA.
    Type: Grant
