Abstract

RNA nanoparticles (NANPs) hold great potential as therapeutics for gene regulation, but their structural flexibility presents challenges in understanding their immunostimulatory properties. Small-Angle X-ray Scattering (SAXS) combined with Wide-Angle X-ray Scattering (WAXS) provides crucial insight into NANP flexibility, which, when integrated with Molecular Dynamics (MD), helps elucidate the structural basis of this behavior. In this talk, I will discuss the experimental design and SAXS/WAXS data collection of NANPs at the Life Sciences X-ray Scattering beamline (LIX) at NSLS-II.
