  • Liquid diagnostic assays utilizing marangoni flow
    Patent number: 10101323
    Abstract: The present invention provides simple and inexpensive assays for the detection of virtually any analyte in any sample that is in liquid form or that can be solubilized. The assays utilize the fluid dynamics of drop evaporation whereby soluble materials, including analytes and particles binding thereto, are drawn to the center of the drop by Marangoni flow and ultimately form a concentrated residual spot. The presence or absence of certain reagents can then be detected through a number of different approaches.
    Type: Grant
