International Classification:

G01N 1/00

US Classification:

356 36

Abstract:

The invention includes sensors and sensing methods for determining cell morphology and/or chemical composition of an analyte. A porous substrate exhibiting a first optical signal is exposed to a target analyte and subsequently monitored for changes in the optical signal. More specifically, a photonic or porous substrate having a well-defined and highly tunable reflectivity or transmission spectrum, such as porous silicon (Si), porous alumina, porous Ge, porous GaAs, porous SiO2 and porous polymer, is used for example. A porous or photonic substrate is exposed to an analyte, such as a cell or other macromolecule, and changes in the scattered light are observed over time to determine cell morphology and/or chemical composition of the analyte using the substrate.
