Using Smartphones in Chemical Analysis.

The review covers the current status and prospects for the development of digital colorimetry using a smartphone as a color recording device. The applications of the rapid analysis methodology for the control of environmental samples, biological fluids, food products, drugs, and some specific samples are systematized. Various approaches are considered, ensuring the formation of an analytical signal in digital colorimetry. The capabilities (advantages and disadvantages) of a smartphone equipped with various software products make it a universal, mobile, rapid, and sensitive tool in the analysis of various samples.
