[Progress in research on LiquiChip technology in biomedical engineering].

As a novel BioChip technique, LiquiChip technique uses fluorescent polystyrene beads as the carrriers of various probes, thus the related reactions of bio-molecules are in liquid system. LiquiChip technique is of use in the methods to detect bio-macromolecules, e. g. DNA detection, immunoassay, cytokine assay, hormone assay, environmental survey and analysis. In comparison to conventional biochip, LiquiChip presents the advantages of high-throughput, high sensitivity, high accuracy, fine repeatability, wide linear range, etc. Now LiquiChip technique is widely used in biomedical engineering field.
