Particle size distributions for mixtures of particles flowing through a nanochannel. (a) Size distribution for a mixture of 50 nm and 75 nm polystyrene nanoparticles. (b) Size distribution for a mixture of 30 nm, 40 nm, and 50 nm gold nanoparticles.Functions, containing two and three Gaussians, are numerically fitted to the distributions in a) and b) respectively, with the correlation coefficients above 0.95.
