原子尺度的计算机模拟已经成为一个强大的工具,以探测在一个非常高的分辨率的结构和动力学性质的无定形和结晶的生物材料,其生物活性的直接影响。特别是,生物活性玻璃(BG)代表了模拟的高度战略重要性的目标,由于他们在广泛的竞技场的修复和再生组织的材料中发挥的核心作用。模拟旨在了解生物活性玻璃的性能,从而揭示了潜力,也是有限的,计算方法,以支持生物材料的合理发展。这篇透视文章探讨了几个关键的挑战,计算机模拟的BG目前正在处理,将需要有效地解决,以实现进一步的实质性进展,在这一领域。相关的例子是新的结构描述符的识别,离子迁移的建模,和纳米样品的模拟,这是讨论有关的基本问题,如有限的空间和时间尺度,可以在原子尺度模拟探测。
Atomic-scale computer simulations have emerged as a powerful tool to probe at a very high resolution the structural and dynamical properties of amorphous and crystalline biomaterials with a direct impact on their biological activity. In particular, bioactive glasses (BGs) represent a target of high strategic importance for the simulations, due to the central role that they play in the broad arena of materials for repairing and regenerating tissues. Simulations aimed at understanding the properties of bioactive glasses thus reveal the potential, and also the limitations, of computational approaches to support the rational development of biomaterials. This perspective article examines several key challenges that computer simulations of BGs are currently dealing with and that will need to be effectively tackled in order to achieve further substantial progress in this field. Relevant examples are the identification of new structural descriptors, the modelling of ion migration, and the simulation of nanosized samples, which are discussed in relation to the underlying issues, such as the limited space and time scales that can be probed in atomic-scale simulations.
