This invention relates to the use of thermodynamically incompatible surfaces in agglutination assays for the express purpose of using the sample as a key component of the detection instrument. Specifically, the invention relates to formation of a lense and a virtual container for rapid mixing via thermal energy by a sample liquid disposed on a superhydrophobic surfaces, and a subsequent specific analyte or overall protein concentration assay using particles agglutination for use in the industrial, environmental, and clinical laboratory test fields.
