Nano-gold quantitative detection analyzer

Abstract

The invention provides a nano-gold quantitative detection analyzer, which comprises a mechanical transmission system, a low-light-level detection system, a control system, a software analyzing system and a power supply system. A sample disc, a screw and a guide rail are arranged on the mechanical transmission system. The sample disc is used for storing a detected sample. The screw and the guide rail are used for driving the sample disc to be in a proper position suitable for a photographing position of the low-light-level detection system. The low-light-level detection system is composed of a camera and a corresponding processing circuit so that the detected sample is photographed and processed. The software analyzing system comprises an upper computer system and a lower computer system. The lower computer system is used for obtaining photographing data of the low-light-level detection system through an image photographing instrument and sending to a PC (Personal Computer) of the upper computer system in a wired or wireless connection manner. The power supply system is used for supplying power to the whole detection analyzer. The control system is used for controlling constant-voltage power supply of the power supply system. The analyzer disclosed by the invention has the advantages of simple structure, wide test linear range and strong openness.

Description

technical field [0001] The invention belongs to an optical detection instrument, in particular to a quantitative analysis instrument suitable for nano-gold immunochromatography / diafiltration for medical detection. Background technique [0002] Nanogold immunochromatography / diafiltration is a high-tech that has developed rapidly in the field of life sciences in recent years. It is widely used in clinical diagnosis and scientific research all over the world. It can also be used in environmental monitoring, criminal investigation, customs inspection, Animal and plant inspection and many other fields. Nanogold immunochromatography / diafiltration is to array a series of addressable biorecognition molecules on a small nitrocellulose membrane, and these molecules bind or react under the same conditions, which requires image acquisition equipment Acquisition of substrate images, and accurate extraction of weak biological signals through corresponding software. [0003] At present, ...

AI Technical Summary

Problems solved by technology

[0004] 1. Immunochromatography / diafiltration images cannot be observed and checked by naked eyes

[0005] 2. Scan the immunochromatography / diafiltration membrane by moving the lens, which will easily affect the accuracy of the optical system

[0006] 3. Using a photomultiplier tube as the detector of the confocal optical path leads to a complex optical path and high cost

[0007] 4. There is no complete nano-gold immunochromatography / diafiltration image processing system

[0008] In the current market, nano-gold immune chromatography / diafiltration image analysis instruments are still in the initial stage, especially for the processing of a large number of nano-gold immune chromatography / diafiltration images, the work is cumbersome and complicated, especially when dealing with a large number of samples. The cost is too high and needs to be improved
