Comparison of the structure and the transport properties of low-set and high-set curdlan hydrogels

► Microscopic structure and the transport properties of low- and high-set curdlan gels. ► Low-set gels are more heterogeneous at the microscopic level than high-set ones. ► The diffusion coefficient distribution reflects the sampled volume by each analyte. ► The gel structural differences are not correlated with their transport properties.
