nanofabricage

Nanofabricage is a term used in some discussions of nanoscale manufacturing to describe the design and construction of structures and devices with features on the order of nanometers. It is closely related to nanofabrication, and in many contexts the two terms are used interchangeably. Because the term is not standard across the literature, its scope can vary, but it generally covers top-down patterning and bottom-up assembly that yield nanoscale architectures.

Nanofabricage employs both top-down lithographic techniques such as photolithography, electron-beam lithography, nanoimprint lithography, and focused-ion-beam milling, as well as bottom-up strategies including chemical synthesis, self-assembly, DNA origami, and templated growth. Hybrid approaches combine patterning with assembly and layer-by-layer deposition to control structure, composition, and function at the nanoscale.

Materials include silicon and other semiconductors, metals, polymers, carbon-based materials such as graphene and carbon nanotubes, and inorganic–organic composites. Applications span electronics and photonics, sensors, energy devices, catalysis, and biomedical devices. Nanofabricage seeks precise features, high integration density, and properties arising from nanoscale confinement and surface effects.

Challenges include achieving reproducible nanoscale features, reducing defects, scaling production, cost, and integration with larger-scale manufacturing. Safety considerations and environmental impacts of nanoscale materials are also important, as are ethical and societal implications. Regulatory frameworks and standards are evolving to ensure quality and compatibility of nanoscale products.

Because 'nanofabricage' is not a universally adopted term, the article typically treats it as synonymous with nanofabrication. The phrase appears mainly in interdisciplinary discussions where designers emphasize the integration of design and fabrication at the nanometer scale.
