Brief description We will use plasmonic absorption of light in metal nanostructures to activate the selective oxidation/reduction of a gas molecule on a semiconductor nanoparticle. This concept will be used to develop a sensing technique capable of measuring ultra-low concentrations (ppb) of breath markers for lung cancer detection. We will fabricate porous sensing films of semiconductor and metal nanoparticles with well-defined light absorption properties. Superior selectivity will be achieved by matching the wavelength of the absorbed light with the required activation energy for oxidation/reduction. This will enable multi-analyte fingerprint identification by on-chip devices with applications ranging from portable medical diagnostics to national security.
