Abstract
Magnetic nanoparticles are widely-used tools over a range of industries, but have particularly powerful biomedical applications for clinical and research diagnostics, clinical therapy, and basic life science research. Many of these applications require consistent sources for magnetic nanoparticles with narrow distributions of magnetic properties, but no technology is now commercially available for manufacturers or users to quantify single-particle magnetic properties with sufficient throughput to provide cost-effective, efficient quality control.Quantum Diamond Technologies has developed a high-throughput magnetic nanoparticle analysis platform using magnetic imaging with quantum defects in diamond. Our system can quantitatively analyze, with high sensitivity and precision, thousands of magnetic nanoparticles in parallel in a matter of minutes with a simple benchtop system. Following our Phase I feasibility study, in this work we will construct an automated prototype for rapid measurements of single-particle magnetization curve data, including magnetic susceptibility, magnetic remanence, and coercivity, key parameters for magnetic particle analysis. We will validate our prototype through comparisons to high-resolution micrographs and conventional bulk magnetic particle measurements. QDTI’s high-throughput, single-particle analytical capability will fill a major gap in current instrumentation, with a low-cost, small-footprint device.
