A novel magnetic fluorescent encoded nanoimmunoassay system for multicomponent detection and separation of the subtrace pathogenic DNA (hepatitis B virus surface gene, HBV; hepatitis A virus poly the protein gene, HAV) was established based on new type of magnetic fluorescent encoded nanoparticles and sandwich immunoassay principle. This method combines multifunctional nanoparticles, immunoassa...

Lab-on-a-chip technologies and the μTAS have gained importance in recent years. The integration of all functions and components needed for the analysis of a sample in a microfluidic system has to be achieved. Magnetic materials are widely used in these systems for various applications such as magnetohydrodynamic pumps and valves. Especially, in terms of separation and detection of biological sa...

We present the results of fieldand temperature-dependent resistivity r and magnetization M measurements which show that colossal magnetoresistance in semimetallic EuB6 is not associated with its bulk Curie temperature TC512.6 K, determined by a scaling analysis of M (H ,T), but with a second phase transition at TM515.5 K. We propose that metallization occurs at TM via the overlap of magnetic po...

Separation of topographic features from magnetic images has been an issue for the past two decades in magnetic force microscopy (MFM). The frequent pickups of the topographic features are interpreted as transitions of the tip between bistable states of the tip-sample assembly in the noncontact and tapping regions. MFM using electrostatic force modulation demonstrates the separation of the topog...

Techniques based on magnetic separation have become increasingly popular among the biological community. Magnetic separation technique offers advantage in terms of subjecting, analyte to very little mechanical stress compared to other methods, they are rapid, often highly scalable, low cost and avoid use of hazardous toxic reagents. Techniques employing magnetism are more amenable to automation...

A new method for magnetic separation of cells is described. Based on cellular concentration of complexed paramagnetic cations from a carrier solution, the method achieves highly repeatable separations, at lower magnetization fields, than existing HGMS cell-separation methods. Feasibility has been shown for erbium and dysprosium, with whole blood as the sample. Single-pass magnetic separation ef...

Separation of chalcopyrite from molybdenite is currently mainly carried out by flotation, but this process costly because the extensive use inhibitors. This study briefly describes a 7.0T/100CGC low-temperature superconducting magnetic separator and discusses its separation principle as well effect induction on molybdenite. A molybdenum (Mo) concentrate assaying 6.00% copper (Cu) 19.01% Mo was ...
