PEI-Au NPs synthesized. (A) Core diameter distribution obtained from the TEM data for the nanoparticles synthesized with an 8 mg/mL PEI solution (NP4). Black bar indicates the average size ≈ 1.5 nm. (B) Analysis of NP4 hydrodynamic diameter ≈ 2.10 nm. Measurements made by the particle size analyzer to the NPs synthesized with a solution of 8 mg/mL of PEI (NP4). (C) NP4 zeta potential ≈ 34 mV. (D) Representative TEM image of NP4.
