System and method for solution based multiparameter analysis of analytes

There is described a system for multiparameter analysis of analytes. The system comprises: 1) primary supports ( 1 ) with a largest dimension ( 3 ) of 500 mum or less suspended in use in a fluid solution; 2) each primary support ( 1 ) comprises an identification means ( 2 ) for identification thereof; 3) at least one primary analyte ( 12 ) is bound to each primary support ( 1 ); 4) a secondary analyte ( 12 ') is suspended in use in the fluid solution; and 5) a measuring means ( 25 ) is arranged in communication with the fluid solution for monitoring interaction between the primary analyte ( 12 ) and secondary analyte ( 12 '). The system is distinguished in that: 6) secondary supports ( 1 ') with a largest dimension at the most the same size as the largest dimension ( 3 ) of the primary supports ( 1 ) are suspended in use in the fluid solution; 7) each secondary support ( 1 ') comprises an identification means ( 2 ') for identification thereof; 8) at least one secondary analyte ( 12 ') is bound to each of the secondary supports ( 1 '); and 9) the measuring means ( 25 ) is arranged to detect any post-reaction interaction between one or more primary analyte ( 12 ) and one or more secondary analyte ( 12 ') by detecting the identification means ( 2, 2 ') of the primary and secondary supports ( 1, 1 ') attached thereto. There is also described a method of multiparameter analysis of analytes using the system.
