报告摘要:

With the rapid development of nano-science, an atomic force microscopy (AFM) has been playing an increasingly important role in many elds. An AFM has the ability to image and manipulate samples at micro-nano scale with the nano-level resolution, however, it still faces some drawbacks severely limiting its performance. Therefore, the speech presents the research on advanced imaging strategies and automated manipulation methods for the AFM. Specifically, focusing on the image distortion caused by hysteresis nonlinearity, thermal drift and vertical drift, advanced image distortion correction algorithms are first presented to improve the imaging quality of the AFM. Subsequently, aiming at the issue that the resonance frequency of the AFM scanner restricts the scanning speed, improved scanning strategies are proposed to achieve fast imaging of the AFM. Finally, some micro-nano manipulation methods including manipulation visualization, rapid elasticity measurement, automated micro-nano lettering and cell injection/grab are exhibited in the speech to highlight the practical application of the AFM.

  

随着纳米科学的飞速发展,原子力显微镜(AFM)在许多领域发挥着越来越重要的作用。AFM能够以纳米级分辨率在微纳米尺度上对样品进行成像和操作,但是,它仍然面临一些严重限制其性能的缺点。因此,报告将重点介绍AFM的高级成像策略和自动化操作方法的研究。具体而言,针对滞后非线性、热漂移和垂直漂移引起的图像失真,首先提出了先进的图像失真校正算法,以提高AFM的成像质量。随后,针对AFM扫描仪的共振频率限制扫描速度的问题,提出了改进的扫描策略以实现AFM的快速成像。最后,报告将展示一些微纳操作方法,包括操作可视化、快速弹性测量、自动微纳刻字和细胞注射/抓取,以突出AFM的实际应用。
