Founded by physicists Laura Philips and David Grier, Spheryx develops particle-characterization instruments and analytical services built around its patented Total Holographic Characterization® technology. Its xSight system measures suspended particles in complex fluids while distinguishing particles of similar size by composition, giving researchers and manufacturers a closer look at formulations such as biologics and wastewater. The company’s scientific leadership combines holographic microscopy expertise with experience in soft matter, optics and biopharmaceutical applications.
