To generate rough surfaces in Monte Carlo simulations, we use the 2 + 1 solid-on-solid model of deposition with rapid transient diffusion of newly arrived atoms supplied at glancing angle. The surfaces generated are employed to scrutinize the effect of surface roughness on adsorption of globular and anisotropic rodlike proteins. The obtained results are compared with the available experimental data for Ta deposition at glancing angle and for the bovine serum albumin and fibrinogen uptake on the corresponding Ta films.
为了在蒙特卡罗模拟中生成粗糙表面，我们使用了2 + 1固-固沉积模型，新到达的原子以掠角供应并具有快速瞬态扩散。所生成的表面用于研究表面粗糙度对球状和各向异性棒状蛋白质吸附的影响。将所得结果与掠角下钽沉积以及相应钽膜上牛血清白蛋白和纤维蛋白原吸附的现有实验数据进行比较。
