Abstract:
A method for detecting a target analyte comprising:(a) irradiating a complex with at least one wavelength of electromagnetic radiation in the range of from about 100 nm to about 1000 nm, wherein said complex comprises a sample suspected of containing said target analyte and a sensor composition, and (b) detecting a luminescent response in the range of from about 200 to about 800 nm, wherein said sensor composition comprises at least one porous semiconductor material modified with at least one recognition element, wherein the pore structure of said porous semiconductor material is substantially free of retaining pores, wherein said recognition element is capable of specifically binding to said target analyte, and wherein said luminescent response is produced by said porous semiconductor composition and is modified upon binding of said target analyte to said recognition element.
