Вирус Западного Нила (род Flavivirus) принадлежит антигенному комплексу японского энцефалита семейства Flaviviridae и способен вызывать лихорадку или тяжёлую болезнь Западного Нила. Для повышения скорости обнаружения рекомбинантного белка Е вируса Западного Нила предложен метод экспресс-детекции с использованием разработанного перспективного аналитического устройства на базе биосенсора. В основе биосенсора лежит полевой транзистор, изготовленный методом оптической литографии по технологии «кремний на изоляторе». Конструкция биосенсора модернизирована – изменена топология кристалла (в центре сформирован один электрод заземления, вокруг которого расположены 20 полевых транзисторов), а поверхность кристалла дополнительно покрыта слоем оксида гафния для стабилизации электрических характеристик. Детекция белка с помощью биосенсора основана на измерении амплитуды тока в цепи исток-сток биосенсора с иммобилизованными на поверхности его затвора моноклональными антителами в ответ на появление в анализируемой пробе антигена – рекомбинантного белка Е вируса Западного Нила. Экспериментально установлено, что биосенсор способен детектировать белок концентрацией 10 пг/мкл. Дальнейшие исследования направлены на определение погрешности измеряемых концентраций и статистической достоверности результатов, полученных с помощью биосенсора.</p></abstract><trans-abstract xml:lang="en"><p>It was noted that the detection time of West Nile virus protein E by standard methods – immunoenzyme assay for West Nile virus antigen, antibody seroconversion, polymerase chain reaction with reverse transcription, virus isolation and neutralization assay, is at least one hour. West Nile virus (genus Flavivirus) belongs to the Japanese encephalitis antigenic complex of the family Flaviviridae and is capable of causing West Nile fever or severe West Nile disease. To increase the detection rate of recombinant protein E of West Nile virus, an express detection method using the developed promising biosensor-based analytical device was proposed. The biosensor is based on a field-effect transistor fabricated by optical lithography using silicon-on-insulator technology. The biosensor design was modernized – the topology of the crystal was changed (one ground electrode was formed in the center, around which 20 field-effect transistors are located), and the crystal surface was additionally covered with a hafnium oxide layer to stabilize the electrical characteristics. Protein detection by means of the biosensor is based on the measurement of current amplitude in the source-to-source circuit of the biosensor with monoclonal antibodies immobilized on the surface of its gate in response to the appearance of the antigen – recombinant protein E of West Nile virus – in the analyzed sample. It was experimentally established that the biosensor is capable of detecting protein concentration of 10 pg/μl. It is necessary to continue further studies to determine the error of measured concentrations and statistical reliability of the results obtained by the biosensor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биосенсор</kwd><kwd>метод экспресс-детекции</kwd><kwd>вирус Западного Нила</kwd><kwd>полевой транзистор</kwd><kwd>модификация поверхности</kwd><kwd>инфекционные заболевания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biosensor</kwd><kwd>rapid detection method</kwd><kwd>West Nile virus</kwd><kwd>field effect transistor</kwd><kwd>surface modification</kwd><kwd>infectious diseases</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке государственного задания Государственного научного центра вирусологии и биотехнологии «Вектор» Роспотребнадзора ГЗ-21/21 и государственного задания бюджетной темы «Изучение молекулярно-генетических и молекулярно-биологических механизмов развития распространенных терапевтических заболеваний в Сибири для совершенствования подходов к их ранней диагностике и профилактике», 2024–2028 гг.
