Abstract

This paper presents a new multiplexed assay system based on microparticles encoded by the magnetic axes from aligned superparamagnetic nanoparticles (SMNP). The encoded microparticles consisting of a UV curable polymer and SMNPs were easily fabricated by exposure to a static magnetic field and photopolymerization. When placed in a magnetic field, the encoded microparticles can be decoded and used for multiplexed assays by their respective tilted angles. For confirming multiplexing capability, we simultaneously assayed four types of pathogens: Bacillus subtillis, Salmonella typhimurium, Staphylococcus aureus and Escherichia coli O157:H7.
