# What is a mixture in which particle size averages between 1 nm and 1000 nm?

An atom is roughly 0.1 nm in diameter so we're looking at a mixture of particles between about 10 and 10 000 atomic lengths. Some proteins might be towards the upper end of this scale (Biologist I'm not, but it's in the right order of magnitude) and glucose is ${C}_{6} {H}_{12} {O}_{6}$ so not far off.
