The BioSAXS beamline is one of the most recently developed beamlines at the Australian Synchrotron. Specifically optimized for solution small angle x-ray scattering (SAXS) experiments, BioSAXS offers researchers the ability to study nanoscale systems in solution under various conditions. Structural biology and soft matter research are among the most productive areas of research at the Australian Synchrotron. The use of solution SAXS to study these systems is expanding, particularly in regard to protein structure, protein-DNA/RNA interactions, polymer solutions, nanoparticles and liquid crystal phases. The BioSAXS beamline accommodates these expanding research interests by delivering a high x-ray flux beam (exceeding 1014 ph/s) which reduces the required sample concentration, while producing strong signal with low instrument background. BioSAXS can accommodate most SAXS experiments for a wide range of particle sizes, with a q-range of 0.003-1.5 Å-1. Radiation sensitive samples can be studied using the specially designed CoFlow sample environment. The CoFlow setup offers a temperature-controlled sample environment with automated sample loading and the ability to couple size exclusion chromatography immediately prior to SAXS data acquisition. The combination of sample environment with optimised beam parameters make BioSAXS superbly positioned to study the nanostructure of solution-based systems. The highly automated processes of the BioSAXS beamline build on the existing capabilities of the SAXS/WAXS beamline to ensure the Australian Synchrotron continues to offer researchers world-leading scattering measurements.
