Quantifying and dispensing of magnetic particles in a self-assembled magnetic particle array
Source abstract
Abstract
We develop a low-cost, mass-production process for creating rod-shaped glass-coated magnetic particles consisting of a magnetic metal core and glass shell structure. We investigate their magnetic properties by analyzing their optical absorbance in suspension as a function of the orientation of a 1 mT magnetic field. From the response we derive that the magnetization of the particles is 0.1 MA/m. We demonstrate an automated system that quantifies and dispenses a large amount of RGMPs by magnetic self-assembly on a high-volume plate patterned with an array of holes. This automatic dispenser can provide packaging forms with the smallest unit of RGMPs for in-vitro diagnostics and is expected to reduce the time and effort required for the assembly and packaging process.
