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.
纳米粒子的自组装是纳米技术中的一项重要工具，具有众多应用，包括薄膜、电子学和药物递送等领域。我们通过实验和理论研究了离子纳米粒子在玻璃基板上的沉积过程。我们的理论模型由二维晶格上的随机协同吸附和蒸发过程组成。通过探索胶体溶液中纳米粒子的初始浓度与沉积在基板上的粒子密度之间的关系，我们将理论模型的沉积速率与浓度联系起来。
