In recent years, the field of nanotechnology has become increasingly prevalent in the disciplines of science and engineering due to it's abundance of application areas. Therefore, the ability to study and characterize these materials is more relevant than ever. Despite the wealth of simulation and modeling studies of nanoparticles reported in the literature, a rigorous description of the interface of such materials is rarely included in analyses which are pivotal to understanding interfacial behavior. We propose a novel method for constructing the continuous intrinsic surface of nanoparticles, which has been applied to a model system consisting of a sodium dodecyl sulfate micelle in the presence of testosterone propionate. We demonstrate the advantages of using our continuous intrinsic surface definition as a means to elucidate the true interfacial structure of the micelle, the interfacial properties of the hydrating water molecules, and the position of the drug (testosterone propionate) within the micelle. Additionally, we discuss the implications of this algorithm for future work in the simulation of nanoparticles. Graphical Abstract ᅟ.
近年来,由于纳米技术应用领域广泛,它在科学与工程学科中变得越来越普遍。因此,研究和表征这些材料的能力比以往任何时候都更加重要。尽管文献中报道了大量关于纳米颗粒的模拟和建模研究,但对这类材料界面的严格描述在对理解界面行为至关重要的分析中却很少涉及。我们提出了一种构建纳米颗粒连续本征表面的新方法,并将其应用于在丙酸睾酮存在下由十二烷基硫酸钠胶束组成的模型系统。我们展示了使用我们的连续本征表面定义作为阐明胶束真实界面结构、水合水分子的界面性质以及药物(丙酸睾酮)在胶束内位置的一种手段的优势。此外,我们讨论了该算法对未来纳米颗粒模拟工作的影响。图形摘要ᅟ。
