Abstract
A method includes binding a probe to an analyte present in a sample, wherein the probe comprises a binder bonded to a metal particle that is capable of releasing metal ions when contacted with a reagent solution. The method includes contacting the metal particle with the reagent solution to release the metal ions, and observing an optical signal from the released metal ions to determine a presence or amount of the analyte in the sample. An associated kit is also provided.
