The pu{pose of the work: the development of a universal portable dual-purpose sensor platform of the "electronic tongue" type based on PFC and intended for rapid diagnosis of food products, water, pollution, environment. Research methods: spectral and colorimetric analysis of PFC, photoluminescence analysis of functionalized nanoparticles for sensors of liquid analytes. The use of a colorimetric approach for the characterization of liquid analytes using sensor structures based on photonic crystals (pC) made of porous silicon (PC) has been tested. The dependences of critical PFC sensor parameters, such as l.s(air) BP position, FWHM and R(l.o(air)) on the optical parameters of the structure and the refractive index of the analyte filling the pores, were investigated and analyzed. Kinetics of adsorption/desorption processes for liquid analytes was experimentally studied applied to increasing the selectivity of sensors. Fluorinated carbon nanoparticles (NPs) were synthesized, their parameters were determined, and their suitability for the recognition of complex organic compounds was demonstrated. Silicon nanorods were grown by chemical etching, and their optical properties were investigated with the aim of using them in sensors and improving the eff,rciency of photoelectric converters. The method of fluorination of nanocarbon fibers was developed and tested. The effect of fluorination on the impedance properties of carbon fibers was investigated. A portable sensor platform for spectral-colorimetric analysis was created.  Product Description popup.authors Gavrilchenko Iryna V. Zaderko Olexander М. Lysenko Anastasiya V. Milovanov Jurij S.
