Abstract:
Human blood is an important medical detection index. With the development in clinical medical detection instruments and detection technology, the requirements for detection accuracy and efficiency have been gradually improved. Fluorescent immunochromatography is a new detection technique. It has the characteristics of high efficiency, convenience, no pollution, and wide detection range. Human blood can be detected quickly using fluorescent immunochromatography. At present, it has received great attention from the field of clinical testing. In this paper, a set of fluorescent immunochromatograp

Abstract:
In the modern food production technologies, the tools and means of simple and rapid testing raw materials, intermediate products and the final ready-to-consume food products are in high demand. This monitoring allows determining the content of toxic and pathogenic contaminants and confirms the compliance of the objects being tested with the established regulatory requirements. Mobile tests tools and means (so called test systems) provide the opportunity of wide range monitoring without involving the specialized laboratories and highly qualified specialists.

Abstract:
Aflatoxin B1 (AFB1) is highly toxic and difficult to prevent. It is mainly produced by fungi and exists in plants and animals and is classified by the World Health Organization as a class I carcinogen, posing a serious threat to human and animal health. Therefore, it is important to establish an efficient, sensitive, and on-site detection method for AFB1 to protect human health. The immunochromatographic test strip method is simple, sensitive, and can achieve real-time detection. However, traditional immunochromatographic test strips have low sensitivity due to their relatively weak optical pr

Abstract:
In this article, we describe an immunochromatographic test system developed for rapid serodiagnostics of cattle brucellosis using two markers: Gold nanoparticles (GNPs) and quantum dots (QDs). The test system was compared with immunochromatographic serodiagnostics systems that use only one marker. The approbation of the test system was conducted on samples of cattle sera with low, but diagnostically significant titers of specific antibodies. We show that when two conjugates are used, the intensity of the detectable signal increases by 2–3 times compared with the test system using the QD conjug

Abstract:
Trichinosis is a parasitic disease caused by nematodes of the Trichinella genus, posing significant concerns for both veterinary and medical fields. This disease is widespread in many countries, including Kazakhstan. Trichinosis primarily spreads through domestic and wild animals, and humans can contract it through raw or undercooked meat. In recent years, the spread of trichinosis in Asia, Europe, and other regions has shown an increasing trend. In Kazakhstan, the disease is mainly transmitted through dog, badger, and wild boar meat.

An immunochromatographic test system has been developed for the simultaneous detection of two phycotoxins, domoic acid (DA) and microcystin-LR (MC-LR). The assay is implemented in an indirect competitive format using anti-species antibodies labeled with colloidal gold nanoparticles. The instrumental/visual detection limits are 2/80 and 0.05/0.3 ng/mL for DA and MS-LR, respectively; the assay duration is 18 min. The applicability of the developed test system for the determination of phycotoxins in seawater is shown. This work was supported by the Russian Science Foundation (project no. 20-43-07

Abstract:
The main types of control points described in the literature in flow test systems based on nucleic acids are considered: streptavidin (1), DNA with hetero- (2) and homo-sequences (3) are immobilised on the control point. It was shown that in addition to Watson-Crick interactions and biotin — streptavidin interactions, other types of interactions are realised, which make a high negative contribution to test specificity.
