Development of a Microfluidic Fluorescent Chip Basis for Express Diagnostics Systems 10.22184/2227-572X.2025.15.2.140.146
Development of rapid and sensitive diagnostic methods is an actual issue of modern medicine. Current methods of diagnostics of myocardial infarction based on determination of enzyme activity (aspartate aminotransferase, creatine kinase, lactate dehydrogenase) have limitations due to low specificity.
A unique direction in this field is the development of systems for express diagnostics of various pathologies based on microfluidic devices and their components – microchips. This approach uses the principle of a modified transparent matrix that allows photometric analysis by turbidimetry and nephelometry methods. The work presents the development of a framework for a rapid diagnostic chip based on specific peptides and a fluorescent dye.

Study of Acid-Base Properties of Polymer Sorbents Based on Rhodanine Derivatives 10.22184/2227-572X.2025.15.2.148.155
The article presents the results of studies of acid-base properties of polymer sorbents based on rhodanine derivatives: polystyrene-azo-o-phenol-azorhodanine (PAFAR), ARA‑8p-p-carboxybenzene azorodane (ARA‑8p-p-KBAR) and AN‑31‑p-carboxybenzene azorodane (AN‑31‑p-KBAR). The sorption capacity of the sorbents for sodium ion and ionization constants of functional-analytical groups of sorbents were determined by potentiometric titration. The calculated values of sorption capacity for sodium ion for PAFAR, AN‑31‑p-KBAR and ARA‑8p-p-KBAR were 3,87 mmol/g, 13,27 mmol/g and 9,67 mmol/g, respectively. The values of the ionization constants of the functional groups of the sorbents were also calculated: for PAFAR – pK1 = 8,21 and pK2 = 9,39; AN‑31‑p-KBAR – pK1 = 9,21 and pK2 = 10,16; ARA‑8p-p-KBAR – pK1 = 10,26 and pK2 = 10,80.

Food Coloring Research: Methodological Approaches and the Current State of the Problem 10.22184/2227-572X.2025.15.2.156.161
With the influx of foreign food products to the Russian market, the issue of creating a domestic regulatory framework regulating physico-chemical methods for the identification and determination of synthetic dyes in food products has become acute. Despite the introduction of standardized methods for the control of synthetic dyes in beverages, caramels, spices, canned fruit and frozen desserts, and the increased capabilities of federal agencies overseeing the entry of substandard adulterated food products into retail outlets, the problem remains urgent. The updated regulatory and technical framework should cover all types of domestic and imported food products, take into account current trends in the development of analytical instrumentation, the relevance and capabilities of new equipment to use its potential in improving the food quality control system.

Determination of Fat-Soluble Vitamins by Online SPE/2D HPLC 10.22184/2227-572X.2025.15.2.94.97
Interest in two-dimensional HPLC (2DLC) in pharmaceutical analysis has been rapidly growing in recent years, as evidenced by recent journal publications and presentations at analytical conferences. Although the technology and theory of two-dimensional separations were introduced more than 30 years ago, 2DLC applications of liquid chromatography have mainly been used in proteomics, natural product, biological sample and polymer analysis and have been limited to pharmaceutical analysis until recently. The increased interest is likely due to new demands in pharmaceuticals and recent advances in 2DLC hardware, software and column technology. This article describes a hardware and software system based on the Sintecon HPLC 10.600 chromatograph for analyzing samples with complex matrices in 2D liquid chromatography mode. The advantages of the Sintecon chromatograph compared to other commercially available systems are listed.

Application of Additive Technologies in Analytical Chemistry 10.22184/2227-572X.2025.15.2.122.131
Today is marked by the active introduction of additive technologies into various fields of science and production, allowing the creation of devices, functional prototypes and structures with complex geometry. The use of additive technologies in analytical chemistry opens up new opportunities for researchers: the time and economic costs of developing and manufacturing new devices, reactors, specialized chemical glassware, etc. are significantly reduced. One of the most promising areas is associated with the use of 3D printing to create new equipment and produce parts with a complex internal spatial configuration, including for the repair of analytical equipment. The article describes the equipment and materials used in additive technologies, and examples of their successful application to solve problems of analytical chemistry.
