Agarose gel (0.7%) electrophoresis images collected from AuNPs capped with different ligands. Gel conditions are given in the bottom right, and the samples were prepared using a mixture of 3 μL of glycerol and 47 μL of AuNPs (10 nM). Note that tris-borate-EDTA buffer (TBE, 0.5×, pH 8.3) promotes instant aggregation of citrate- and DTT-capped AuNPs.
