Mission Statement

Bio-SANS was designed and optimized for analysis of the structure, function, and dynamics of complex biological systems.

Instrument Description

Bio-SANS is the cornerstone of the Center for Structural Molecular Biology (CSMB) at Oak Ridge National Laboratory. Bio-SANS is designed and optimized for establishing an understanding between structure, and function, and dynamics of complex biological systems. The Bio-SANS instrument is supported by additional capabilities offered through CSMB that include biophysical characterization and X-ray scattering infrastructure. In addition, a dedicated chemical and biological sample preparation laboratory is located adjacent to the Bio-SANS instrument to facilitate optimal experimentation

Bio-SANS user Brad O’Dell talks about using small-angle neutron scattering to study cyanobacteria.
