About

Florence Layburn is a rising leader in biophysics and single-molecule imaging, whose work is redefining the sensitivity and reliability of quantitative microscopy. Her primary research focuses on developing advanced surface passivation strategies to minimize nonspecific binding—a critical barrier in single-molecule studies. In her landmark 2024 paper, “Improved Imaging Surface for Quantitative Single-Molecule Microscopy,” Layburn introduced the RainX-F127 (RF-127) surface, a simplified yet powerful coating that achieves up to 100-fold reduction in nonspecific binding from protein aggregates compared to conventional methods. This breakthrough enables researchers to observe molecular interactions with unprecedented clarity and accuracy, directly enhancing the reproducibility of single-molecule fluorescence assays. Already garnering 14 citations in under a year, her work is rapidly becoming a standard reference in the field. Layburn’s contributions are particularly impactful for studying protein dynamics, DNA-protein interactions, and cellular signaling at the molecular level. Her innovative approach to surface chemistry promises to accelerate discoveries in quantitative biology, making her a key figure to watch in the next generation of microscopy toolbuilders.
