Abstract

In the present article, the platform known as the Photonic Nose is presented as a versatile sensing concept for analysis of both liquid and vapor phase samples. By use of photonic crystal structures known as Bragg stacks with Bragg diffraction peaks within visible wavelengths, sensing events can be easily monitored by use of a digital camera to register color changes resulting from infiltration of analytes. We demonstrate the discrimination between pure solvent atmospheres, bacteria headspace as well as aqueous amine solutions as case examples of the variety of samples that can be analyzed with the platform.
