In fact, it's so tiny it can only be seen through a microscope.
Researchers have created a nanotechnology image of the president-elect using tube-shaped molecules of carbon atoms.
Research team leader John Hart says the "nanobama" isn't meant as any sort of political statement.
He adds it's a fun way to demonstrate what can be done with nanotubes.
The researchers have also created a nano Joe Biden and a nano-flag.
Scientists say nanotechnology could eventually impact everything from medicine to space flight.
