GW Nanofabrication and Imaging Center
Bridging Life Sciences and Materials Sciences Research
The George Washington University (GW) Nanofabrication and Imaging Center (GWNIC) features state-of-the-art microscopy instrumentation and a newly-constructed Class 100 cleanroom. GWNIC provides university-wide core infrastructure for research in engineering, chemistry, physics, biology, public health, medicine and biomedical sciences. Located at the heart of GW’s Foggy Bottom Campus, the GWNIC is a catalyst for cross-disciplinary collaboration.
Nanofabrication
GWNIC features ~5,000 sq ft of Class 100 cleanroom with major instrument clusters for lithography, deposition, etching, measurement and characterization.
Imaging
GWNIC comprises two imaging suites (~5,500 sq ft) with the latest light, confocal and electron microscopes. Sample preparation equipment and services are also available.
GWNIC Correlative Light and Electron Microscopy Workshop
April 24-28, 2023
The George Washington University (GW) Nanofabrication and Imaging Center (GWNIC) presents a five-day correlative microscopy workshop.
Featured Research
Segmentation performed on FIB-SEM images from corneas. Several individual axons are assigned different colors. One axon (aqua) moves in a different direction compared to the rest of the axons in the cluster shown.

Segmentation performed on FIB-SEM images from corneas. Intraepithelial Corneal Basal Nerves (ICBNs) are assigned the color yellow and the corneal epithelial basement membrane is assigned the color purple.
