Bubbles on the nanometer scale were produced by a special method on solid s
urfaces. Atomic Force Microscopy (AFM) was used to detect these bubbles. It
shows that nanobubbles can be seen clearly in the interfaces of liquid/gra
phite and liquid/mica. In AFM images, the nanobubbles appeared like bright
spheres. Some of the bubbles kept stable for hours during the experiments.
The bubbles were disturbed under high load during AFM imaging. The conforma
tion of the bubbles is influenced by the atomic steps on the graphite subst
rate. In addition, a shadow was found around the bubbles, which was due to
the interactions between a bubble adhered to the tip and a bubble on the su
bstrate.
