Исследование стандартных характеристик ВНВ было проведено с помощью анализа траекторий наночастиц (АТН) и проточной цитометрии; характеристик наночастиц золота — с помощью лазерной корреляционной и абсорбционной спектроскопии. Полуколичественный анализ специфических популяций ВНВ в составе плазмы доноров и пациентов был проведен с помощью технологии AuNP-аптасенсора, предполагающей колориметрический метод оценки результатов.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: разработаны и протестированы AuNP-аптасенсоры на основе девяти различных ДНКаптамеров. Показано увеличение количества КРР-специфичных ВНВ в плазме пациентов с КРР по сравнению с плазмой доноров и пациентов с болезнью Крона. После проведенной оптимизации показателей диагностической значимости AuNP-аптасенсора составили: AUC — 0,95, специфичность — 88,89%, чувствительность — 90,63%. В группе пациентов с КРР показана корреляция между размерами опухоли и результатами, полученными с помощью AuNP-аптасенсора. </p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: оценка количества КРР-специфичных ВНВ плазмы при помощи технологии AuNP-аптасенсор является перспективным методом диагностики КРР.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>OBJECTIVE</title><p>OBJECTIVE: to develop and validate a novel method for diagnosing colorectal cancer (CRC) by semi-quantitative analysis of specific populations of plasma small extracellular nanovesicles (SEVs) using AuNP-aptasensor technology.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: the study used plasma samples from patients with colorectal cancer (n = 37), patients with Crohn’s disease (n = 10), and healthy donors (n = 32). Investigation of standard SEVs characteristics was performed using nanoparticle tracking analysis (NTA) and flow cytometry; gold nanoparticle characteristics were analyzed using dynamic light scattering (DLS) and absorption spectroscopy. Semi-quantitative analysis of specific SEVs populations was performed using AuNP-aptasensor technology, employing a colorimetric method for result evaluation.</p></sec><sec><title>RESULTS</title><p>RESULTS: AuNP-aptasensors based on nine different DNA aptamers were developed and tested. An increase in the number of CRC-specific SEVs in the plasma of patients with CRC was shown compared to the plasma of donors and patients with Crohn’s disease. Optimized AuNP-aptasensor revealed following indicatirs of diagnostic significance: AUC — 0,95, specificity — 88,89%, sensitivity — 90,63%.In the group of patients with CRC, the correlation between tumor size and the results obtained using the AuNP-aptasensor was evaluated</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: assessing the quantity of CRC-specific plasma SEVs using AuNP-aptasensor technology is a promising method for diagnosing CRC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аптамер</kwd><kwd>аптасенсор</kwd><kwd>внеклеточные нано-везикулы</kwd><kwd>золотые наночастицы</kwd><kwd>диагностика</kwd><kwd>колоректальный рак</kwd></kwd-group><kwd-group xml:lang="en"><kwd>аptamer</kwd><kwd>aptasensor</kwd><kwd>extracellular nanovesicles</kwd><kwd>gold nanoparticles</kwd><kwd>diagnostics</kwd><kwd>colorectal cancer</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследования проводились в рамках выполнения государственного задания «Разработка и клиническая апробация тест-системы для диагностики онкологических заболеваний органов желудочно-кишечного тракта на основе технологии AuNP-аптасенсора», регистрационный номер 1023022000032-9.</funding-statement><funding-statement xml:lang="en">the studies were conducted as part of the state assignment “Development and clinical testing of a test system for diagnosing oncological diseases of the gastrointestinal tract based on AuNP-aptasensor technology”, registration number 1023022000032-9.</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">Мерабишвили М.В.
