" Magnetic nanoparticles for pathogen detection

Magnetic nanoparticles can be functionalized with antibodies that target bacterial pathogens in patient samples. When these functionalized nanoparticles are combined with fluorescent tags or quantum dots they can significantly speed up the diagnostic process. The benefit of using magnetic particles is that they can be rapidly separated out of solution with a magnetic separation rack. The separated particles can be analyzed for the presence or absence of fluorescence to determine if the target bound to the nanoparticles. This method is also known as a sandwich immunoassay. Another magnetic particle detection method utilizes quantitative polymerase chain reaction (qPCR) amplification of the target genetic material. The amplification of the genetic material is only possible if it is present in the first place. So, the magnetic nanoparticles are incubated with the patient sample before being isolated with a magnetic separation rack. The genetic material is isolated and amplified to determine if it is present in the patient sample. These two diagnostic strategies using magnetic nanoparticles are rapid and easy to scale down to a portable system. "
