  Self-assembly of nanoparticles is an important tool in nanotechnology, with
numerous applications including thin films, electronics, and drug delivery. We
study the deposition of ionic nanoparticles on a glass substrate both
experimentally and theoretically. Our theoretical model consists of a
stochastic cooperative adsorption and evaporation process on a two-dimensional
lattice. By exploring the relationship between the initial concentration of
nanoparticles in the colloidal solution and the density of particles deposited
on the substrate, we relate the deposition rate of our theoretical model to the
concentration.
