    Magnetic nanoparticles in DNA separation. A prerequisite for many molecular methods (e.g. PCR, real-time PCR and sequencing) applied to microorganism detection is the separation of high-quality DNA from complex mixtures. However, due to the frequent presence of cellular or other contaminants in such complex mixtures, many reactions and

    Small magnetic nanoparticles that have surfaces decorated with stimuli-responsive polymers can be reversibly aggregated via a stimulus, such as temperature, to enable efficient and rapid biomarker separation. To fully realize the potential of these particles, the synthesis needs to be highly reprodu

    Sep 21, 2014 Based on sharp geometry of Ni nanowires, we developed a novel high-gradient magnetic separator that was composed of a nanowires array and a uniform magnetic field. When suspension of magnetic nanoparticles (MNPs) flowed through it, the relatively large nanoparticles or clusters were removed from the suspension so that the size distribution can be improved. The separation resulted
