Abstract

Целью работы является создание рабочего макета для регистрации флуоресценции от микрофлюидных чипов при проведении полимеразной цепной реакции (ПЦР). В работе рассмотрены основные параметры ПЦРреакции в реальном времени. Исследованы и проанализированы существующие коммерческие приборы для ПЦРреакции в реальном времени. Приведены характеристики основных элементов, использованных при создании макета устройства для детектирования флуоресценции. Представлены результаты экспериментов при проверке работоспособности элементов макета и микрофлюидных чипов. Проверена способность фотоприемного устройства (цифровой камеры) регистрировать сигнал флуоресценции раствора флуоресцеина с концентрациями 10‾⁵, 10‾⁶ и 10‾⁷, которым заполняется микрофлюдный чип. Продемонстрирована работоспособность собранного макета при проведении ПЦРреакции в реальном времени. Собранный в результате выполнения работы макет может в дальнейшем использоваться для постановки на микро-флюидных чипах ПЦРв реальном времени при биологических и медицинских исследованиях. Предметом исследования в данной работе является макет устройства детектирования фуоресценции от микрофлюидных чипов; методами исследования являются: флуорометрия, спектрофотометрия и ПЦР-анализ на микрофлюидных чипах.

The aim of this work is to create a working model for registering fluorescence from microfluidic chips during polymerase chain reaction (PCR). The paper discusses the main parameters of the PCR reaction in real time. Existing commer-cial instruments for real-time PCR reactions have been investigated and analyzed. The characteristics of the main elements used to create a prototype of a device for detecting fluorescence are given. The results of experiments in testing the performance of the elements of the model and microfluidic chips are presented. The ability of a photodetector (digital camera) to register the fluorescence signal of a fluorescein solution with concentrations of 10‾⁵, 10‾⁶ and 10‾⁷, which fills a microfluidic chip, has been tested. The efficiency of the assembled model has been demonstrated when carrying out a PCR reaction in real time. The model assem-bled as a result of the work can be further used for setting real-time PCR on microfluidic chips in biological and medical research. The subject of research in this work is a mock-up of a device for detecting fuorescence from microfluidic chips; research methods are: fluorometry, spectro-photometry and PCR analysis on a mycrofluidic chip.
