Up-converting phosphor bio-detector and method for detecting sampling test strips

Abstract

The invention provides an up-converting phosphor (UCP) bio-detector and a method for detecting sampling test strips. The UCP bio-detector consists of an optical system, a photo-detector, a control system, a driving module, a stepping motor and a scanning platform for placing the test strips, wherein, the control system comprises a micro-processor, a photo-detector interface, a signal acquisition circuit, a driving module interface, an LCD (liquid crystal display) module, a matrix keyboard, an RFID (radio frequency identification) module, a D / A (digital to analog) converter, a memorizer, an SD (secure digital) memory card and a micro-printer; and each test strip consists of test paper mounted inside the casing of the test strip and an RFID card, the test paper comprises a sample pad, a detection band and a quality control band, and the RFID card contains the information including test paper ID, substances to be detected, decision values, a parameter A and a parameter B. The control system of the invention has the advantages of simple design and convenient debugging, and the biological immunological detection can be carried out rapidly and accurately.

Description

technical field [0001] The invention relates to an up-conversion phosphorescence biological detector, in particular to an up-conversion phosphorescent biological detector and a detection method for sample test strips. Background technique [0002] The up-conversion phosphorescence biodetector is a new type of biological immunological detection instrument that uses the above-conversion phosphorescent material as a marker. Materials with up-conversion luminescent properties are compounds composed of rare earth metal elements doped in crystal lattices. The luminescence mechanism is that up-conversion luminescent materials emit a visible photon by absorbing two or more infrared photons. The up-conversion luminescent material is prepared into nano-scale particles, which are marked on biomolecules, and the particles will emit visible phosphorescence under the excitation of infrared light. According to the presence or absence of phosphorescence and its strength, the properties and...

Problems solved by technology

At the same time, during the working process, when the data acquisition system is collecting data, the control display system is in a waiting state without doing any operations, and does not perform data processing and other operations until the collection is completed, thus wasting resources and increasing production costs

[0007] 2) Requires frequent manual intervention

Moreover, after the data collection is completed, the operator must manually intervene to determine the position of the test strip and the quality control strip
