The International Iberian Nanotechnology Laboratory (INL) is an intergovernmental organization created by the founding member states, Spain and Portugal, to foster interdisciplinary research in nanotechnology. INL works on addressing major challenges in nanomaterials, nanoelectronics, NEMS/MEMS, nanomedicine, nanotechnology applications in environmental and food safety, energy, and quantum materials. The cleanroom facilities at INL are comprehensively equipped for micro- and nanofabrication on substrates ranging from individual chips to 200 mm wafers. Advanced materials synthesis and device fabrication efforts are supported by excellent facilities for structural, electronic, magnetic, optical, and mechanical characterization. A broad range of in-house expertise, a flexible management structure, and well-equipped laboratories enable interdisciplinary research teams working in areas such as medical imaging, energy conversion and storage, lab-on-a-chip technology, and biosensors.
