About

Ashleigh M. Raczkowski is a pioneering researcher at the intersection of nanotechnology and structural biology, whose work has fundamentally advanced cryo-electron microscopy (cryo-EM) sample preparation. Her most notable contribution is the development of self-blotting nanowire grids, a breakthrough innovation that addresses one of cryo-EM’s most persistent challenges: producing vitrified specimens with consistent, optimal ice thickness. This self-blotting technology, introduced in her highly cited 2017 paper, eliminates the need for manual blotting steps, dramatically improving reproducibility and throughput in high-resolution imaging. By integrating nanowire arrays directly into the grid design, Raczkowski’s approach enables automated, reliable sample vitrification—a critical enabler for structural studies of proteins and macromolecular complexes. Though early in her career, her work has already garnered significant attention (4 citations on the foundational paper) and is poised to become a standard tool in cryo-EM workflows. Her research bridges materials science and structural biology, offering a practical solution that empowers researchers to capture near-native molecular structures with unprecedented ease and consistency.
