Sensor array type cold light instrument

Abstract

The invention discloses a cold light instrument with a detection array, which can simultaneously detect the light signals of multiple samples, and can simultaneously receive the multiple light signals through a light sensing component. The present invention at least includes a detection array, the detection array includes a plurality of detection terminals, which are used to capture the luminescent signal emitted by the sample to be tested; a plurality of optical signal transmission components, which are respectively extended from each detection terminal, so as to transmit the luminescence signal; and a light sensing component, which is used to receive a plurality of luminescence signals transmitted by the light signal transmission components, and convert them into data that can identify the luminescence signal of the sample to be tested.

Description

technical field [0001] The invention relates to a luminometer detecting device, in particular to a detection array luminometer, which can detect light signals of multiple samples at the same time, thereby greatly saving detection time. Background technique [0002] In biological detection technology, the use of luminescent light reaction results as a test indicator for quantitative or qualitative tests has become a common test method for testing gene expression, gene analysis, immune analysis and cell proliferation in laboratories. The luminescence reaction does not require an additional excitation light source like the fluorescent reaction, and there is no danger of radioactive elements. At the same time, it does not require the process of sample concentration or dilution like the traditional enzyme immune reaction. It has the advantage of convenience in the experiment. . [0003] The known luminometers are mainly divided into two categories, one is a tube-type luminometer...

AI Technical Summary

Problems solved by technology

This kind of known luminescence instrument only has a single detection end, so when detecting the microdisk, the detection end must move sequentially in the X and Y axes between the wells to detect each well respectively

On the one hand, this detection method is quite time-consuming, and it is also quite inconvenient for large-scale screening and analysis tests, and the components and devices capable of moving in the X and Y axes are relatively expensive, which will increase the cost of setting up this type of cold light instrument

On the other hand, for experiments with a relatively short reaction time to luminescence, if the time difference between the reaction and detection is too large, the results may also have errors due to different reaction time conditions.

What's more, the detection end moves back and forth frequently. After a long period of use, the component itself will cause an error in the positioning of the detection end due to thermal expansion, which will cause the detection data to deviate, thus reducing the accuracy of the instrument.
