Characterization of Ludox-TMA nanoparticles Ludox-TMA was supplied by Sigma-Aldrich as 30 wt-% silica dispersion in water. Aliquots of the sample were diluted and dialyzed for 1 week using membranes with molecular-weight cut-off of 14 kDa. Bigger aggregates were removed from the silica dispersion by filtration through 0.22 µm filters. The sample was characterized by SAXS, nitrogen adsorption and by transmission electron microscopy (TEM), as explained for Lys-Sil particles in the main text.
