2021 Bronze Medal Award


The group is recognized for developing a first-of-its-kind reference material for particle size and shape that mimics particle degradation products found in biotherapeutic drugs. To create this reference material, the group developed novel ways of forming irregular and highly transparent microscopic particles and a suite of novel particle characterization techniques. A private company has commercialized the material, following the NIST method. This reference material will aid industry in accurately quantifying particle counts in biotherapeutics, enhancing drug quality and patient safety.
