Lateral flow immunochromatography assay is a new instantaneous detection technology that employs a chromatographic membrane and labeling materials for detection.This detection technology is convenient,fast,and inexpensive,and is therefore widely used in a number of different fields,such as biomedicine,disease detection,food safety,environmental protection,and so on.Traditional lateral flow immunochromatography assay relied on visual observation and provided only qualitative or semi-quantitative results.By utilizing various types of markers and sensitive detection devices,lateral flow immunochromatography assay enables quantitative and multi-component detection of the analytes.The research progress on the lateral flow immunoassay detection system and its current applications in the context of recognition elements,labeling materials,and detection instruments were reviewed in this paper.

Surface plasmon resonance (SPR) sensor is an optical detection technique enables real-time and dynamic monitoring of biological samples. SPR-based biosensors have remarkable characteristics such as label-free detection and high sensitivity, making them important tools for studying molecular interactions. The recognition element, which plays a critical role in SPR sensors,which could specifically identify and capture of target analytes, closely influencing the selectivity performance of the sensor. The progress on SPR sensors in pharmaceutical research were reviewed, which focused on the application of recognition elements such as antibodies, aptamers, molecularly imprinted polymers, and metal nanoparticles.
