Method for characterizing and/or determining samples

摘要

Characterizing and/or determining a sample employs an array of at least two of different interacting surfaces, at least one of which comprises a non-specific interacting material non-specifically interacting said sample,at least one labelling reactant, and/or combination of the sample and at least one labelling reactant. The sample and at least one labelling reactant is introduced to interact with said interacting surfaces of said array, wherein said labelling reactant is adapted to change at least one electromagnetically readable property of at least one interacting surface of said array. Then at a predetermined time point said electromagnetically readable property of at least one of said at least two different interacting surfaces of said array is detected to obtain a fingerprint of said sample; and the sample is characterized and/or determined by comparing said fingerprint of said sample with i)at least one fingerprint of at least one corresponding sample, ii)at least one finger print of an array obtained without a sample, and/or iii)at least one fingerprint of known samples.
