The Marcus Nanotechnology Building (MNB) is a Georgia Institute of Technology facility.

In addition to being the headquarters for the IEN, the building houses the largest cleanroom laboratory dedicated to the fabrication, characterization, and assembly of biomedical and semiconductor devices in the Southeast United States.

The laboratories are available to global academics, industry and government personnel on a fee recovery basis enabling students, scientists and engineers who perform research on nanotechnology to study the characteristics and behavior of atoms and molecules, and to use that knowledge to create new materials and tiny nano-scale tools and machines.

The Information and Communications Laboratory was previously located on the site, and has been moved to GCATT.

The Electronics Research Building, established in 1966,[5] was demolished, and construction began in Fall 2006/Spring 2007.
