摘要

研究了带壳球形纳米粒子与金属表面的电动力学相互作用。计算了吸附势和纳米粒子表面的空间局域场分布，并研究了它们与表面结构的关系。同时考虑了纳米粒子的线性极化和非线性极化。结果表明，纳米物体的存在增加了纳米颗粒的吸附，导致纳米颗粒表面的局部场增强。并对该模型在生物医学领域的应用前景进行了展望。

Influence of the Surface Roughness on the Nanoparticle Adsorption: Theoretical Consideration

The electrodynamic interaction between a spherical nanoparticle with a shell and a metal surface has been studied. Adsorption potential and spatial local field distribution in the system ‘nanoparticle-surface’ were calculated, their dependence on the surface structure have been studied. Both linear and nonlinear polarizabilities of the nanoparticle were taken into account. It was shown that presence of nanosized objects on the surface increases the nanoparticle adsorption and leads to the local field enhancement on the nanoparticle surface. The possibility of application of the model to the biomedicine has been described.
