Abstract

A method of detecting a biomarker in one embodiment includes identifying a quantity of biomolecule types in a sample, exposing the sample to a plurality of test sites, wherein the number of test sites in the plurality of test sites is equal to or greater than the identified quantity of biomolecule types, establishing, for each of the plurality of test sites, a respective test environment, wherein the test environment for each of the plurality of test sites is different from the test environment for each of the other of the plurality of test sites, obtaining a detection signal associated with each of the plurality of test sites, and determining the concentration of one of the biomolecule types based upon the obtained detection signals.
