我们提出了一种方法，它允许附加微米大小的球体的原子力显微镜悬臂以可重复的方式。用最少量的胶水将不同尺寸的球体附着在悬臂上的预定位置。这是通过使用一个光学显微镜和一个激光拉微量移液管，这保证了无损处理的微妙的悬臂梁。该方法采用了一个简单的设置，包括立体显微镜和显微操作器。用扫描电子显微镜拍摄修改后的悬臂梁的图像，以澄清胶合球体在悬臂梁上的位置。电子色散X射线分析表明，微球的表面没有覆盖的胶水，除了在接触区域的悬臂。(c)2006年，美国物理学会。
We present a method, which allows attaching micrometer sized spheres to an atomic force microscope cantilever in a reproducible manner. Spheres of different size with a minimum amount of glue are attached to a predefined position on the cantilever. This is performed by using an optical microscope and a laser-pulled micropipette, which guarantees nondestructive handling of the delicate cantilever beams. The method employs a simple setup consisting of a stereomicroscope and a micromanipulator. Images of the modified cantilevers were taken with a scanning electron microscope to clarify the position of the glued spheres on the cantilever. Electron dispersive x-ray analysis reveals that the surface of the microsphere is not covered with the glue, except at the contact area to the cantilever. (c) 2006 American Institute of Physics.
