The Foundry operates on a principle rare in high-end science: if you intend to publish your results and acknowledge the facility, access costs nothing. Over a thousand scientists from universities, private industry, and research institutes use the Foundry each year. They submit proposals reviewed by an external panel of subject-matter experts, and an accepted proposal grants one year of access to staff expertise and instrumentation. Researchers who prefer to keep their work proprietary can still use the facility - they simply pay full cost-recovery rates. The model reflects a belief that the best way to accelerate nanoscience is to remove barriers between good questions and good equipment. Forty-five scientific and technical staff members collaborate directly with visiting researchers, providing instrument training, experiment planning, and guidance through the particular challenges of working at scales where the rules of classical physics begin to blur.

The Foundry organizes its capabilities into seven specialized facilities, each covering a distinct corner of nanoscience. The Imaging and Manipulation of Nanostructures facility combines electron, optical, and scanning probe microscopy to characterize everything from hard crystalline materials to soft biological matter. Nanofabrication handles advanced lithography and thin-film processing, building electronic, magnetic, and photonic devices at scales invisible to the naked eye. A theory group provides computational support, modeling molecular junctions and self-assembling biological structures. The Inorganic Nanostructures facility, founded by Nobel laureate A. Paul Alivisatos, designs semiconductor nanocrystals and carbon nanotubes. Biological Nanostructures, founded by Nobel laureate Carolyn Bertozzi, engineers new materials from biopolymers and develops probes for bio-imaging. Organic and Macromolecular Synthesis studies soft materials and porous frameworks. And the National Center for Electron Microscopy, an independent DOE facility since 1983 that merged with the Foundry in 2014, offers an array of electron microscopes for high-resolution materials characterization.

The Foundry's founding directors read like a shortlist for the most consequential chemists and physicists of their generation. Carolyn Bertozzi, who served as director from 2006 to 2010, won the Nobel Prize in Chemistry in 2022 for her development of click chemistry and bioorthogonal reactions. A. Paul Alivisatos, who founded the Inorganic Nanostructures facility, pioneered the synthesis of semiconductor nanocrystals and later became president of the University of Chicago. Omar Yaghi, director from 2012 to 2013, is one of the founders of the field of reticular chemistry. The facility sits within Lawrence Berkeley National Laboratory's broader ecosystem of user facilities, including the Advanced Light Source synchrotron, the National Energy Research Scientific Computing Center, and the Joint Genome Institute. This concentration of capability - particle accelerators, supercomputers, gene sequencing, and nanofabrication within walking distance of one another - gives visiting scientists access to a density of tools found almost nowhere else.

Nanoscience, by definition, operates at the boundary between disciplines. A single Foundry project might require a chemist to synthesize a nanoparticle, a physicist to model its electronic behavior, a biologist to attach it to a cell membrane, and an engineer to incorporate the result into a working device. The Foundry's proposal system encourages exactly this kind of collision, accepting projects from materials science, physics, electrical engineering, environmental engineering, biology, and chemistry. The work produced here feeds into energy storage, solar technology, biomedical imaging, and computing - practical applications emerging from research conducted at scales where a single atom out of place changes everything. It is quiet work, largely invisible to the public, performed in a building most Berkeley residents drive past without a second glance. But the instruments inside can see individual atoms, and the questions asked here shape technologies that do not yet exist.
