Description

technical field [0001] The invention relates to the technical field of microfluidic fluorescence detection, in particular to a multi-channel microfluidic fluorescence detection device and method. Background technique [0002] At present, microfluidic chips are widely used in the fields of biological research, drug detection, food safety and chemical analysis. On the microfluidic chip platform, induced fluorescence detection has become one of the mainstream detection methods with its mature technology and high sensitivity. Traditional photoelectric sensors widely used in microfluidic fluorescence detection mainly include photomultiplier tubes, avalanche diodes, and photodiodes. There are certain limitations in aspects such as multi-channel detection adaptability. Therefore, the development of microfluidic fluorescence detection technology urgently needs a method with low preparation difficulty and cost, low power consumption, high photoelectric gain, easy integration with m...
