APPLICATION OF SPECTROSCOPIC METHODS IN RESEARCH OF NEW FORMATIONS IN BIOLOGICAL TISSUES
Objective. To consider the application of optoelectronic methods for the study of neoplasms and the study of the composition of biological tissues. Methods. Conceptual, process, logical and systemic analysis. Results. Since the issue of the emergence and spread of oncology is still relevant in the modern world, the main task for healthcare is to minimize the number of patients. In this regard, the article describes methods for the timely detection of malignant cells in healthy tissue can significantly speed up. Conclusion. At present, there is a clear trend in the formation and development of instrumentation related to the use of parameters of the interaction of optical radiation with biological objects for the purposes of non-invasive diagnostics all over the world. Optical non-invasive diagnostics involves the use of optical radiation for intravital probing of the patient's tissues and organs in order to obtain diagnostic information about the structure of the body area under study from reflected light. Such devices are devices in which the levels and dynamics of accumulation of certain biochemical components over time - blood oxyhemoglobin, porphyrin compounds, NADH, etc. - are evaluated by optical methods in vivo in the areas of the patient's body available for examination. Thus, it was found that when irradiated with UV light, some human malignant tumors fluoresce in the orange-red region of the spectrum, which is explained by the presence of porphyrins in the tumors.
