В ходе исследования подготовлена культура клеток рака яичников для подкожного введения лабораторным мышам, для создания калибровочной шкалы приготовлены растворы с различной концентрацией таких клеток. Измерение БИК-спектров проводилось на живых лабораторных мышах (в заранее отмеченных точках) под анестезией до прокола и после введения клеточной культуры. Выявлены спектральные характеристики, чувствительные к изменению числа клеток в точке измерения (интенсивность пика, сдвиг базовой линии), и оценено минимальное надежно распознаваемое число клеток злокачественных опухолей по графику зависимости величины поглощения на длине волны 1200 нм от логарифма числа клеток в растворе.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to develop a technique for assessing the minimum number of malignant cells recognizable by their diffuse reflectance spectra obtained in the near infrared region (NIR) using compact spectrometric equipment. In the course of the study, a culture of ovarian cancer cells was prepared for subcutaneous injection into la- boratory mice; solutions with various concentrations of such cells were prepared to create a calibration scale. Measure- ment of NIR spectra was carried out on live laboratory mice (at pre-marked points) under anesthesia before puncture and after the introduction of cell culture. Spectral characteristics that are sensitive to changes in the number of cells at the measurement point (peak intensity, baseline shift) have been identified, and the minimum reliably recognizable number of malignant tumor cells has been estimated from the graph of the dependence of the absorption value at a wavelength of 1200 nm on the logarithm of the number of cells in solution.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптоволоконный зонд</kwd><kwd>оптическая спектроскопия</kwd><kwd>злокачественные клетки</kwd><kwd>онкология</kwd><kwd>ближняя инфракрасная область</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fiber optic probe</kwd><kwd>optical spectroscopy</kwd><kwd>malignant cells</kwd><kwd>oncology</kwd><kwd>near infrared region</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке гранта Президента РФ №MK-2192.2021.4</funding-statement><funding-statement xml:lang="en">The study was supported by a grant from the President of the Russian Federation No. MK2192.2021.4</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jaafar H.
