Metalloporphyrins are excellent molecules for sensing specific targets due to their reactivity could be tune changing the metallic center and the porphyrin ligands. In general, the metalloporphyrin spectra shifts are small, in the order of 30 nm, making necessary a spectrophotometer for transducing the analyte concentration.We propose combing a metalloporphyrin thin film (MTF) and a photonic crystal (PC), a nanostructured optical filter synthesized from two oxide thin films with different refractive index, in order to develop a versatile and portatile sensing dipositive for small molecules.We propose combing a metalloporphyrin thin film (MTF) and a photonic crystal (PC), a nanostructured optical filter synthesized from two oxide thin films with different refractive index, in order to develop a versatile and portatile sensing dipositive for small molecules.
