Description
Technical Field
The utility model relates to a sample collection storage device especially relates to hand-held type SPR detector's multichannel liquid sample collection storage device.
Background
Surface Plasmon Resonance (SPR) is a physical optical phenomenon. At the interface between two transparent media (e.g., glass and water) with different refractive indices, when a light beam is incident from a high refractive index medium to a low refractive index medium, the light beam will be refracted and reflected. When the angle of incidence increases to a certain value, the angle of refraction is equal to 90 ° when the light exits in a direction tangential to the interface, the angle of incidence at this point being called the critical angle. If the angle of incidence exceeds the critical angle, the incident ray will not enter another medium but will be totally reflected back into the incident medium, where total internal reflection occurs.
In fact, although all incident light is reflected, an electromagnetic field called evanescent wave penetrates through the interface into the low refractive index medium, with an exponential decay of the energy. If a metal film (generally, a gold or silver film) is plated on the interface, free electrons on the surface of the metal film are excited by incident light to generate charge oscillation, thereby forming surface plasma. When the incident angle or wavelength of light is adjusted to a proper value, the frequency and wave number of the surface plasmon and the evanescent wave are equal, and the two are coupled with energy to form surface plasmon resonance. The total reflection condition at the interface is destroyed during resonance, and the incident light energy is transferred to the surface plasma wave, so that the reflected light intensity is sharply reduced in propagation, and the phenomenon of attenuated total reflection is presented. The angle of incident light at which the reflected light is completely extinguished is called the resonance angle (SPR angle). The resonance angle changes with the change of the refractive index of the medium on the surface of the metal film, and the change of the refractive index is proportional to the mass of the molecules bonded on the surface of the metal. Thus, by analyzing the resonance angle, information on the intermolecular interaction can be obtained.
The SPR sensing technology has the characteristics of no need of marking, sensitivity to surface characteristics and substance changes, real-time performance, rapidness, easiness in automation realization and the like. The technology is widely applied to the fields of life science, clinical diagnosis, drug screening, food safety, environmental monitoring and the like, and detection objects comprise proteins, nucleic acids, hormones, toxins, pesticides, cells, microorganisms and the like.
