Gold nanoparticles produced via the sonoelectrochemical method undergo three stages of centrifugation and dilution to adjust the concentrations of both stabilizer and nanoparticles in the solution. Simple models are employed to examine these processes, aiming to gain insights into the formation of nanoparticles of varying sizes. The constant-number Monte Carlo method simulates the aggregation of gold nanoparticles, with results compared against experimental data.
