Abstract
Currently, clinical and laboratory diagnostics is undergoing active technological changes. Each medical organization is equipped with equipment that allows you to automate and speed up the process of assessing the patient’s condition. However, classical research methods can be lengthy and do not always meet the needs of the doctor, which requires the use of more sensitive and specific analyzers. This article examines the role of biosensors, portable devices consisting of a biological element (antibody, antigen, enzyme of a DNA fragment or RNA), a physical signal converter and a working solution and their role in modern laboratory diagnostics. In modern clinical practice, biosensors are widely used for the early detection of various diseases, monitoring the general health of patients, providing a personal approach to the treatment and prevention of diseases. The main advantages of using them are: the speed of obtaining results, the possibility of repeated use, as well as high sensitivity and specificity, which allows the attending physician to obtain more detailed information about the patient’s condition and choose the right treatment tactics. The review analyzed biosensor devices used in modern medical practice for the analysis of genetic material, cellular and chemical analysis of blood, visualization of internal organs and serological studies.
