Cytometric bead array（ CBA） is a new analytical technique,which can achieve real-time and rapid detection of targeted components in a small amount of sample. With many advantages of high throughput screening,high specificity and sensitivity,low cost,easy operation and good repeatability,this CBA technique has been widely used for the detection of various components in foods,agricultural products and environmental samples. Recently,it has got significant development in rapid detection of small molecules.This review briefly introduced the theory of CBA technique,summarized the application in the analysis of small molecules,such as mycotoxins,pesticide residues,shellfish toxins,and then prospected the application of trace small molecules detection in the complex matrices of traditional Chinese medicine and the development trend of it.
