Description
Technical Field
The invention relates to the technical field of real-time quantitative instant detection of biological test paper, in particular to a universal small-sized mobile phone shooting and analyzing device for detecting lateral flow test paper.
Background
The lateral flow test paper detection technology such as early pregnancy test paper, nucleic acid test paper, blood glucose test paper and other detection devices greatly simplifies the traditional detection procedures such as Polymerase Chain Reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) (patents US201662425839P, ZL 201810413748.2). Moreover, the detection technology adopts paper as a main preparation material, and has a series of advantages of simple production, convenient use, low price, environmental protection and the like (ZL 201810591801.8). The traditional lateral flow test paper detection technology mainly judges and indicates the content of a target object in a sample to be detected by using indicator particles such as chromogenic particles (such as nano gold, carbon nano rods, magnetic nano particles and the like), and can directly observe a detection result by naked eyes. But quantitative analysis and poor accuracy in identifying relatively weak signals are difficult to achieve by direct visual observation.
In order to realize quantitative analysis of real-time detection, researchers have utilized physical properties (light, heat, and magnetism) of different color-developing particles, respectively shoot optical signals of nanogold and carbon nanoparticles with a camera, record and analyze thermal signals of nanogold with a thermal imager, and obtain magnetic signals of magnetic nanoparticles with a magnetic signal reader (patent US201715802120), and then obtain the relationship between the concentration of a target and a detection signal, and perform quantitative analysis. However, these methods still suffer from the disadvantages of large background noise, small scanning range, long distance, need of expensive and large-scale detection instruments, and professional technical personnel, and are not suitable for applications in remote areas with shortage of medical resources.
With the rapid development of smart phone technology in recent years, many mobile phones have integrated a high-definition photographing function, have a high-performance processor, and can perform analysis processing of image software. Therefore, by combining with the smart phone technology, the lateral flow test paper detection can realize portable, real-time and intelligent optical quantitative detection and analysis (CN2017101961584, CN 2018113041934). Therefore, the mobile phone photographing-based detection and analysis method does not need expensive auxiliary equipment, and is expected to be widely applied to paper-based biological information detection in remote areas, resource-deficient areas and the like. However, the existing additional shooting device for the smart phone is often designed with a supporting shell aiming at a specific mobile phone, so that the mobile phones with different sizes, cameras, positions and numbers are difficult to match, and the shooting and analysis of the optical signals of the lateral flow test paper are not facilitated due to the different light intensities of the flash lamps (CN 201710218782X). Therefore, a universal small mobile phone photographing device for detecting the lateral flow test paper is needed to be developed.
