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 ...

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0036] see first figure 1 , figure 1 It is a structural block diagram of the reflective photometer of the gold standard immune test strip of the present invention. As can be seen from the figure, the gold standard immune test strip reflective photometer of the present invention is mainly composed of a scanning platform 2, an optical system, a photoelectric conversion and signal amplification system, and a data acquisition and control system:

[0037] Placed on the scanning platform 2 is the gold-labeled immunological test strip 1 to be tested. The scanning platform 2 drives the gold standard immune test strip 1 to complete the reciprocating scanning movement. The photometer of the present invention scans and measures the absorption light intensity of gold nanoparticles f...
