Abstract

A method for simultaneously detecting and separating a target analyte such as a protein or other macromolecule that includes providing a porous silicon matrix on the silicon substrate, exposing the porous silicon matrix to an environment suspect of containing the target analyte, observing optical reflectivity of the porous silicon matrix; and correlating the changes in the silicon substrate to the target analyte.
