In the nanoprecipitation technique, nanoparticle formation occurs as a result of interfacial turbulence between two unequilibrated liquid phases.

- plotted stacked in Figure 2 and a smoothened line was added to improve readability. From bottom to top data are shown for a reference without any added gold and therefore no nanoparticle formation (grey filled stars). Further samples were taken 75 minutes (black open squares), 115 min (red open circles
- the nanoparticle production [23][29]. This will not be necessarily true for metal nanoparticle formed at the cell-wall at the outside of the cell, but even this constitutes a more restricted location than in a solution. In inorganic systems effects of the confinement on the nanoparticle formation have

- , or vice versa, could be due to the mechanism of nanoparticle formation. Cd2+ ions are freely available from the Cd(OAc)2 precursor, whereas the counter part is released from SeSO32− much slower. Therefore, the concentration of Cd(OAc)2 governs the number of nucleation sites available for the growth
