Abstract: Lateral flow chromatography analysis technique(LFAs)characterized as simple,rapid,economic,and efficient one and can quickly presents the test results under the laboratory condition. New chemical antibody,nucleic acid aptamer body becomes a novel identifying component because of its in vitro screening,easy synthesis and modification,small batch difference and so on. Aptamer lateral flow chromatography analysis technique is the novel and fast detection technique of combing lateral flow tomography technology with aptamer. The LFAs is mainly used for qualitative,semi-quantitative and quantitative detection of contaminants in food safety,environment and clinical analysis. This paper reviews the LFA susing the aptamer combined with markers such as fluorescent,nano-gold and magnetic beads,as well as their applications in the rapid detection of fungal toxins through optics,colorimetry,surface-enhanced raman scattering,which aims at providing a reference in designing aptamer lateral flow chromatography analysis biological sensing technology.
