Аннотация: A modern level of nanotechnology allows us to create conceptually new test systems for chemical analyses and to develop sensitiveand compact sensors for various types of substances. However, at present, there are very few commercially available compactsensors for the determination of toxic and carcinogenic substances, such as organic solvents that are used in some construction materials.This article contains an overview of how 3D photonic crystals are used for the creation of a new test system for nonpolarorganic solvents. The morphology and structural parameters of the photonic crystals, based upon a crystalline colloidal array with asensing matrix of polydimethylsiloxane, have been determined by using scanning electron microscopy and by the results of specularreflectance spectroscopy based on the Bragg–Snell law. A new approach has been proposed for the application of this sensor inchemical analysis for the qualitative detection of saturated vapors of volatile organic compounds due to configuration changes of the photonic bandgap, recorded by diffuse reflectance spectroscopy. The exposure of the sensor to aromatic (benzene, toluene andp-xylene) and aliphatic (n-pentane, n-heptane, n-octane and n-decane) hydrocarbons has been analyzed. The reconstitution of spectralparameters of the sensor during the periodic detection of saturated vapors of toluene has been evaluated.
