A New 3D Simulation Method for the Construction of Optical Phase Contrast Images of Gold Nanoparticle Clusters in Biological Cells

Figure 5

A cluster of 42 gold nanoparticles randomly distributed in a spatial sphere with a radius of 1𝜇m at a cell location opposite to the location of the nucleus (𝑥=2𝜇m, 𝑦=0,𝑧=0). The nucleus is located at 𝑥=−2𝜇m. The gold nanoparticle size (diameter  =  50 nm) on right-hand graph is slightly exaggerated.
