Abstract
A method of detecting analytes in a microfluidic sample includes introducing at least one type of analyte, at least one type of carrier particle, and a fluid into a mixing chamber of a system. The at least one type of analyte binds to a site on the at least one type of carrier particle to form a microfluidic suspension including at least one analyte-bound particle suspended in the fluid. The at least one analyte-bound particle is separated from the fluid by exposing the suspension to physical forces, magnetic forces, or combinations thereof. A spectrophotometric property of a solution is altered using the at least one analyte-bound particle. The altered spectrophotometric property is measured with an optical detection system.
