Nanofabrication Overview

Principles

Definition

Nanofabrication is a multidisciplinary research field and methodological approach concerned with the design, creation, and manipulation of structures, devices, and materials with feature sizes typically ranging from 1 to 100 nanometers. It investigates techniques for precisely controlling matter at the atomic and molecular scales, enabling the realization of systems exhibiting novel physical, chemical, and biological properties derived from nanoscale phenomena.

Scalable Replication Era era

Michael S. Feld [1], associated with the Harvard–MIT Division of Health Sciences and Technology [3] and Harvard University [4], emerged as a leading figure in the Scalable Replication Era. His contributions in this era include pioneering Single Molecule Detection Using Surface-Enhanced Raman Scattering (SERS) [7], a milestone that demonstrated the feasibility of detecting molecules at ultra-low concentrations and spurred scalable, high-sensitivity nanofabrication. Catherine J. Murphy [2], linked to the University of South Carolina Sumter [5] and the University of Maryland, Baltimore [6], helped advance collaborative nanopatterning efforts that bridged laboratory demonstrations and scalable processes. Her work, exemplified by Wet Chemical Synthesis of High Aspect Ratio Cylindrical Gold Nanorods [8], highlighted how solution-based synthesis could produce anisotropic nanostructures for tunable plasmonics, a cornerstone of replication-focused nanofabrication in this era.

Directed Template Fabrication era

Younan Xia [1] is associated with Stanford University [3] and The Wallace H. Coulter Department of Biomedical Engineering [4] during the Directed Template Fabrication era. His key contribution in this era is the development and dissemination of Soft lithography for micro- and nanoscale patterning [7], which enabled reproducible, low-cost templates and guided assembly essential for directed templating. George M. Whitesides [2] is affiliated with Harvard University [5] and the Massachusetts Institute of Technology [6] during this era. Whitesides's co-authorship of Soft lithography for micro- and nanoscale patterning [7] helped establish scalable patterning strategies that underpinned template-driven device architectures and defect control in directed assembly.

Programmable Assembly Era era

George M. Whitesides and Paul Alivisatos epitomize programmable nanofabrication in the Programmable Assembly Era, with Whitesides’ pioneering self-assembly, soft lithography, and scalable patterning complementing Alivisatos’ work on programmable nanocrystal assemblies and bottom-up nanostructures. Yi Cui and Yury Gogotsi anchor material platforms enabling wafer-scale, manufacturable nanosystems, as Cui’s scalable dispersion and printable ultrathin conductors and Gogotsi’s MXene family discovered with M. Naguib provide flexible, conductive routes for nanoscale integration. Naguib and Gogotsi’s MXenes spur printable interconnects, while Robert J. Wood advances nanoscale robotic actuation and Nader Engheta develops programmable metamaterials for tunable RF and mechanical responses. Collectively, these figures illustrate the era’s convergence of material discovery, assembly automation, and manufacturing-ready process control that underpins deployable nanoelectronic and adaptive systems.
