Using crystals and light, scientists unlock new ways to grow materials on-demand

East Lansing MI (SPX) Oct 14, 2025 Researchers at Michigan State University have discovered how to "draw" on demand the crystals used in many crucial technologies, from solar panels and LED lighting to medical imaging. Appearing in the journal ACS Nano, the breakthrough was achieved by striking gold nanoparticles with a single laser pulse. This work was supported with funding from the U.S. Department of Defense.
