The SAPUCAIA Group is responsible for the management and operation of the SAPUCAIA beamline of the synchrotron light source Sirius,  at the Brazilian Synchrotron Light Laboratory (LNLS).

The SAPUCAIA beamline will be dedicated to studies of morphology and supramolecular organization of different types of materials using the Small Angle X-ray Scattering (SAXS). The application of this technique ranges from biological studies, such as the structure of proteins and interactions of drugs with tissues, to applications in catalysis and processes of formation of nanoparticles or mesoporous materials. Due to the high flux of the  beamline and camera’s low background, time-resolved studies in all areas of research are also planned.

Sapucaia Beamline

SAPUCAIA is a beamline dedicated to small-angle X-ray scattering for solid, liquid and gel-like samples. This technique allows to comprehend fundamental biological mechanisms through the determination of complex structures of proteins without the need for their crystallization. Moreover, this technique also is capable to give information of many different nanometric structures and agglomerates.
