Исследовать особенности технологии производства микрофлюидных чипов методом «мягкой» литографии, включая этапы: проектирования структуры каналов; изготовления форм различными методами на подложках из стекла, фольгированного текстолита и кремния; подбора необходимого полимера, режимов его полимеризации, обработки формы антиадгезивом, заливки компаундом, и последующего отделения, «активации» и последующего склеивания полученной заготовки с подготовленным стеклом.</p></sec><sec><title>   Методы</title><p>   Методы. Проведение экспериментов по фотолитографии осуществлялось при использовании монохроматического источника светового излучения Anycubic Wash and Cure 2.0 на подложках фольгированного текстолита, предметного стекла и кремниевых пластин. Изготовление опалубки для конструктов было реализовано на принтере FDM – FlyingBear Ghost 5. В качестве полимерной основы использовался полидиметилсилоксан марок Силагерм 2104 и 2106. Для процесса склеивания применялась плазменная установка низкого давления Diener PICO с воздушной средой.</p></sec><sec><title>   Результаты</title><p>   Результаты. Исследованы аспекты технологии изготовления микрофлюидных чипов методом «мягкой» литографии, рассмотрено влияние времени экспонирования, способа укрывания шаблоном для переноса, а также материала подложки. Проведены эксперименты с различными режимами полимеризации ПДМС, различными вариантами конструктов, исследованы их механические свойства. Изучено влияние давления газов в вакуумной камере при плазменной активации поверхности полимерной реплики на качество формирования структуры в микрофлюидном чипе.</p></sec><sec><title>   Вывод</title><p>   Вывод. Результатом экспериментов стало определение кремниевой подложки как наилучшего материала мастер-формы для мягкой литографии. Определены параметры для упрощенного, удешевлённого и безопасного плазменного склеивания реплики из ПДМС и стекла. Полученные результаты могут быть применены как протоколы изготовления микрофлюидных устройств силами малых исследовательских лабораторий.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Purpose</title><p>   Purpose. To explore the specifics of microfluidic chip manufacturing technology using soft lithography, including the following stages: channel structure design; mold fabrication using various methods on glass, foil-clad PCB, and silicon substrates; selection of the required polymer, polymerization modes, mold treatment with a release agent, compound filling and subsequent separation, activation, and subsequent bonding of the resulting chip to the prepared glass.</p></sec><sec><title>   Methods</title><p>   Methods. Photolithography experiments were conducted using a monochromatic Anycubic Wash and Cure 2.0 light source on foil-clad PCB substrates, glass slides, and silicon wafers. Formwork for the constructs was fabricated using a FlyingBear Ghost 5 FDM printer. Silagerm 2104 and 2106 were used as PDMS. A Diener PICO low-pressure plasma system with an air environment was used for the bonding process.</p></sec><sec><title>   Results</title><p>   Results. Photolithography studies were conducted to determine the exposure time, the method of covering the transfer template, and the substrate material. Experiments were conducted to create constructs and their viability. The effect of gas pressure in a vacuum chamber during plasma activation of the polymer replica surface was studied.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The experiments identified a silicon substrate as the best master mold material for soft lithography. Parameters for simplified, cost-effective, and safe plasma bonding of PDMS and glass replicas were determined. The results can be applied as protocols for the fabrication of microfluidic devices by small research laboratories.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микрофлюидика</kwd><kwd>полимеризация</kwd><kwd>лаборатория</kwd><kwd>микрофлюидный чип</kwd><kwd>мягкая литография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microfluidics</kwd><kwd>polymerization</kwd><kwd>laboratory</kwd><kwd>microfluidic chip</kwd><kwd>soft lithography</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках реализации программы стратегического академического лидерства «Приоритет-2030» (Соглашения № 075-15-2021-1155 и № 075-15-2021-1213)</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the implementation of the strategic academic leadership program "Priority-2030" (Agreements No. 075-15-2021-1155 and No. 075-15-2021-1213)</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">Microfluidic nanomaterials: From synthesis to biomedical applications Illath / K.K.
