We present a new method to create dynamic nanobubbles. The nanobubbles are created between graphene and mica by reducing intercalated water to hydrogen. The nanobubbles have a typical radius of several hundred nanometers, a height of a few tens of nanometers and an internal pressure in the range of 0.5–8 MPa. Our approach paves the way to the realization of nanobubbles of which both size and internal pressure are tunable.
