Anisotropic self-assembly of (bio)polymers and colloidal matter into long-range anisotropic nanostructured materials is a physico-chemical phenomenon widespread in nature which imparts materials direction-dependent properties. Biomimetic and bioinspired approaches aim to explore these effects in the design of novel materials featuring directionally tuned properties, such as diffusivity, light, heat and sound propagation, cell proliferation and mechanical properties.<br/>This paper reports the results of a SAXS study at the high-flux Austrian Elettra Beamline (Trieste, Italy) investigating and comparing the time-resolved nanostructure development of isotropic and anisotropic cellulosic gels evolving from respective cellulose solutions in [EMIm][OAc] and [TMGH][OAc] upon fast and strongly decelerated infusion of the antisolvent ethanol. Furthermore, the two types of gels and derived aerogels are compared with regard to major macroscopic properties.<br/>
