METHODS OF NON-LABORATORY ANALYSIS USING A SMARTPHONE

This review covers methods of analysis using portable devices in combination with smartphones. The review spans works from 2015–2024, with an emphasis on recent years. References to reviews, mainly from the last five years, are provided. Devices used in combination with smartphones are discussed (from smartphone holders to portable visible, UV-Vis, and IR spectrometers, microscopes, and cytometers), amperometric and potentiometric devices, and portable microfluidic analyzers. Options for using smartphones in portable devices for immunochemical analysis, for polymerase chain reaction, and in other variants for determining nucleotide sequences, in microfluidic devices, and in separation methods are considered. Paper-based test systems, photonic crystals, nanozymes, and other special techniques (optoelectrowetting, electrochemiluminescence, hyperspectral imaging, evanescent wave spectroscopy) are reviewed. The main sample types and analytes are listed.
