This paper presents a comprehensive computational investigation aimed at optimizing nanomanipulation techniques by leveraging fullerene-based nanocarriers on curved gold surfaces. Through rigorous potential energy analyses and molecular dynamics simulations, we scrutinize the nuanced effects of temperature variations and nanocarrier wheel sizes on their behavior. Our results reveal an interplay between temperature and nanocarrier performance, wherein smaller-wheeled nanocarriers exhibit heightened efficacy at elevated temperatures, facilitating extended-range motion. Conversely, larger nanocarriers encounter impediments attributed to their augmented mass, constraining their mobility. Further scrutiny into effective velocities and angular velocities elucidate deviations from anticipated movement paths, notably observed in nanocarriers employing C60 fullerene wheels, advocating for the exploration of novel design alternatives. Additionally, our findings underscore the efficacy of specific nanocarrier configurations, notably those equipped with C80, C36, and C50 wheels, showcasing their potential as optimal candidates under distinct operating conditions. By shedding light on the intricate dynamics governing nanocarrier behavior on curved surfaces, this study contributes valuable insights to the advancement of nanoscale material transportation and manipulation methodologies, thereby enriching the discourse within the realms of nanotechnology and nanorobotics.
本文提出了一项全面的计算研究,旨在通过利用基于富勒烯的纳米载体在弯曲金表面上优化纳米操纵技术。通过严格的势能分析和分子动力学模拟,我们仔细研究了温度变化和纳米载体轮尺寸对其行为的细微影响。我们的结果揭示了温度与纳米载体性能之间的相互作用,其中较小轮的纳米载体在高温下表现出更高的功效,有利于进行更远距离的运动。相反,较大的纳米载体由于其增加的质量而遇到阻碍,限制了它们的移动性。对有效速度和角速度的进一步研究阐明了与预期运动路径的偏差,特别是在采用C60富勒烯轮的纳米载体中观察到,这提倡探索新颖的设计替代方案。此外,我们的研究结果强调了特定纳米载体配置的功效,特别是那些配备C80、C36和C50轮的配置,展示了它们在不同操作条件下作为最佳候选者的潜力。通过揭示控制纳米载体在弯曲表面上行为的复杂动力学,本研究为纳米级材料运输和操纵方法的进步提供了有价值的见解,从而丰富了纳米技术和纳米机器人领域的讨论。
