Reflection photometer of gold label immune test paper

Abstract

The invention relates to a reflecting photometer of golden mark immunity test tape that includes scanning platform, optical system, phototranslating and signal multiplication system and data gathering and control system. The scanning platform is used to locate tested golden mark immunity test tape, and the optical system includes plural illuminating optical paths and a receiving optical path. Each illuminating optical path contains a light source and an illuminating condensing lens. The receiving optical path is made up of collimating mirror, filter, condensing lens and slit diaphragm. The phototranslating and signal multiplication system is made up of phototranslating components and pre-amplification circuit, the data gathering and control system is made up of multifunction data gathering card and computer. The invention could accurately judge the tested object and the thickness. It also has the advantages of high sensitivity, objective testing result and flexible to use.

Description

Technical field [0001] The invention relates to a reflection photometer for scanning gold label immune test strips. The device can scan, detect and interpret gold-labeled immune test strips, thereby achieving the qualitative and quantitative identification of pathogens, antigens, antibodies, illegal drugs, major diseases (tumors, cancers, diabetes, etc.) and other target test substances. detection. Background technique [0002] Gold will exhibit many unique optical properties when its size is reduced to the nanometer level, especially absorption spectral properties, which has important application value in fields such as materials science, clinical medicine, and life sciences. Research on the absorption spectrum characteristics of gold nanoparticles shows that when the particle size of gold nanoparticles is between 10nm and 100nm, its absorption peak is between 510nm and 550nm; as the size of gold nanoparticles increases, its absorption peak also increases. increases, and ...

AI Technical Summary

Problems solved by technology

However, the visual observer can only judge the presence or absence of the inspected object according to the depth of the color, and cannot realize the quantitative judgment of the inspected object.

[0007] 2. The objectivity of the measurement results is poor

[0008] 3. Cannot monitor the dynamic process of biological reactions

However, the visual method cannot realize the observation and analysis of the reaction process, so it is impossible to study the immunochromatographic reaction process in depth

Even if the biological response fails, the reason for the failed response cannot be well analyzed by a visual observer
