Purpose: development of a universal portable touch dual-purpose platform type "electronic language" based on PFC and designed for rapid diagnostics of food, environment, water, materials used in industry. Research methods: spectral and colorimetric analysis of PFC, photoluminescent analysis of functionalized nanoparticles for sensory analysis of liquid analytes. The application of colorimetric approach for characterization of liquid analytes using sensor structures based on photonic crystals (FC) of porous silicon (PC). The influence of the parameters of sensory structures such as layer thickness, refractive indices of layers / bi-layers, the position of the middle of the band gap of FC with air-filled pores on the sensory properties of structures and in particular sensitivity was modeled and experimentally determined. Fluorinated carbon nanoparticles (FL) were synthesized, their parameters were determined, and their suitability for the recognition of complex organic compounds was demonstrated. Silicon nano-blades were grown by chemical etching, their optical properties were studied in order to be used in sensors and to improve the efficiency of photovoltaic converters.  Product Description popup.authors Gavrilchenko Iryna V.
