ABSTRACT
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.

As a novel functional material with great application values, magnetic nanobead has been in fast development in recent years. Magnetic nanobead is provided with characteristics of beth polymeric and mag-netic particles, so it can be detected easily fi'om the medium and can be easily located since they can move di-rectionally when motivated by external electric field. The magnetic nanobead is widely used in biomedical engi-neering research due to its unique physical and chemical properties which simplify the complex experiments op-erations and shorten the testing period.
