Biocompatible magnetic nano-particles show great potential in bio-magnetic applications. In this work, the feasibility of magnetically labeled immunoassay using bio-compatible magnetic nanoparticles is investigated. To do this, we study the synthesis technologies for magnetic nano-particles Fe3O4, as well as the coating of various bio-probes onto the magnetic nanoparticles to detect bio-targets, such as proteins, virus, etc. Furthermore, the measurement, magnetoreduction assay, for the amount of bio-targets are developed. The results show such merits as high-sensitivity, high-specificity, high-convenience for magnetoreduction assays using magnetic nanoparticles. The whole assay platform is promisingly applied to food inspection, environment monitoring, and even human diagnosis.
