Abstract

This paper introduces a nanopipette combined with a quartz tuning fork-atomic force microscope system (nanopipette/QTF-AFM), and describes experimental and theoretical investigations of the nanoscale materials used. The system offers several advantages over conventional cantilever-based AFM and QTF-AFM systems, including simple control of the quality factor based on the contact position of the QTF, easy variation of the effective tip diameter, electrical detection, on-demand delivery and patterning of various solutions, and in situ surface characterization after patterning. This tool enables nanoscale liquid delivery and nanofabrication processes without damaging the apex of the tip in various environments, and also offers force spectroscopy and microscopy capabilities.

摘要

本文介绍了一种结合石英音叉原子力显微镜系统的纳米移液器（纳米移液器/石英音叉-原子力显微镜），并描述了对所使用的纳米级材料的实验和理论研究。与传统的基于悬臂的原子力显微镜和石英音叉-原子力显微镜系统相比，该系统具有几个优点，包括基于石英音叉的接触位置对品质因数进行简单控制、有效针尖直径易于变化、电检测、各种溶液的按需输送和图案化，以及图案化后的原位表面表征。该工具能够在各种环境中进行纳米级液体输送和纳米制造过程，而不会损坏针尖顶端，还具备力谱和显微镜功能。
