Meet the Machines: Hummingbird Nanomanipulator

This nanomanipulator can be installed in the Titan TEM and enables us to use AFM probes in the transmission electron microscope to slide, apply contact pressure, measure adhesion, or even make a nano-sized snowman (image 3).

Image 2: Ruikang carefully checks the alignment of the sample with the help of an optical microscope.
Image 3: By picking up and placing metallic nanoparticles on top of each other, we created a 150 nm tall snowman.
