The National Science Foundation (NSF) awarded a $499,944 Project Grant under its Engineering program (CFDA 47.041) to The Regents of the University of Colorado, doing business as the University of Colorado Office of Contracts and Grants Division. The grant, awarded on February 1, 2025, will fund the development of a novel high-resolution and high-sensitivity nanoparticle-based dual-comb magnetic field microscope. The project aims to bridge the gap between existing magnetometer technologies by advancing the synthesis of rare-earth-doped magnetic nanoparticles and utilizing cutting-edge dual-comb microscopy techniques. The resulting microscope is expected to offer unparalleled sensitivity to detect extremely weak magnetic fields and the ability to capture fine details at the micrometer scale, enabling new applications in studying biological processes and mapping magnetic patterns in integrated circuits. The University of Colorado will leverage its expertise in materials science and optical instrumentation to overcome the limitations of current non-invasive magnetic field microscopy.
