摘要：
Dextran-coated magnetic nanocomposites were prepared. A periodate oxidation method was used to further activate the magnetic dextran, forming magnetic polyaldehyde-dextran, which could be conjugated to biomolecules, antibodes. The magnetic labeled nano-scaled bioconjugates could be well blocked with BSA and exhibit high activity by ELISA and immunochromatographic strip assay.
