[Liquichip technology and its application in tear cytokine analysis]

Liquichip (Multiplexed microsphere-based flow cytometric assays) is a new biomolecular detection technology using encoded microspheres suspended in liquid as reaction and detection carrier, which is an integration of flow cytometry,laser technology, digital signal processing and traditional chemical technology. It is a high-throughput analyzer for the target molecular (e.g.nucleic acid and protein) based on the principles of flow cytometry. Liquichip is now widely used in biomedical analyses. This article briefly reviews the principle and characteristic of liquichip and its application in tear cytokine analysis.
