Capillary isotachophoresis for separation of silver nanoparticles according to size
Original language description
Capillary isotachophoresis (ITP) was used for the separation of Ag nanoparticles according to their size. For this purpose, ethanol-water dispersions of Ag nanoparticles stabilized by gelatin were prepared. The ITP separations were performed in a column-coupling system filled with two electrolytes with a pH of leading electrolytes of 7.1 (system I - LE: 10 mM HNO3, epsilon-aminocaproic acid, TE: 10 mM caproic acid) and 4.5 (system II - LE: 10 mM HNO3, imidazole, TE: 5 mM 2-(N-morpholino) ethanesulfonicacid). In both electrolyte systems the four main peak-mode zones of Ag nanoparticles migrating at zone boundaries were identified, however, the better separation was achieved by the system II. The Ag nanoparticle dispersions were also examined by dynamiclight scattering (DLS) and transmission electron microscopy (TEM). The zeta potential and thickness of gelatin double layers adsorbed on the nanoparticles were found to depend on pH. The TEM analysis revealed four size fractions of 4 nm,
