Abstract

The invention provides a self-luminescence type micro-fluidic chip which realizes self-luminescence by means of internally integrating a chemical reaction agent. The chemical reaction agent in the chip is stored at a specific part in the micro-fluidic chip in a sealed liquid bag or cavity, and is prepared from three substances, namely peroxides, an ester compound and fluorescent dye. According to the working principle of the self-luminescence type micro-fluidic chip, the liquid bag is broken under an external action so as to release the chemical agent stored in the bag, then the released chemical agent is subjected to mixing reaction, and therefore, chemical luminescence is realized. In the self-luminescence way, external light source devices and complicated control equipment are not required; and the micro-fluidic chip is simple and convenient to operate and especially applicable to a portable micro total analysis system.

Description

technical field [0001] The invention relates to a microfluidic chip, in particular to a self-illuminating microfluidic chip. Background technique [0002] In recent years, microfluidic chip technology has been widely researched and applied in the fields of biology, chemistry, and medicine. In the application process of microfluidic chips, many chemical and biological reactions and detections often need to be carried out under specific light source irradiation conditions. Therefore, light source control is of great significance in the application of microfluidic chips. [0003] At present, the light reaction or light detection of microfluidic chips is mainly realized by external light sources. However, this method has the following disadvantages: either additional equipment and energy consumption are required, or the preparation process is cumbersome and expensive. These shortcomings have affected the promotion of microfluidic chips, especially in some micro-total analysis...
