Nanotechnology is the manipulation and control of matter at dimensions typically between 1 and 100 nanometers to create materials, devices, and systems with novel properties. It builds on principles from Quantum mechanics, Solid-state physics, Materials science, Chemistry, and Molecular biology, driving advances across sectors such as Electronics industry, Pharmaceutical industry, Aerospace, and Energy industry. Research and commercialization involve collaborations among institutions like MIT, Stanford University, IBM, and National Nanotechnology Initiative-funded centers.

Definition and Scope

Nanotechnology refers to engineering at the nanoscale drawing on concepts from Quantum mechanics, Surface science, Condensed matter physics, Physical chemistry, Biochemistry, Molecular engineering, Optics, Electrical engineering, and Chemical engineering. Its scope includes nanoscale materials (e.g., Carbon nanotube, Graphene, Quantum dot, Fullerene), nanoscale devices (e.g., Atomic force microscope, Scanning tunneling microscope, Nanoelectromechanical systems), and nanoscale fabrication methods (e.g., Electron beam lithography, Self-assembly (chemistry), Molecular beam epitaxy). Interdisciplinary institutions such as National Nanotechnology Initiative, European Commission, Japan Science and Technology Agency, Max Planck Society, and Chinese Academy of Sciences set priorities and fund facilities.

Foundational ideas trace to lectures and writings by figures like Richard Feynman and theoretical proposals by K. Eric Drexler; experimental breakthroughs came with instruments such as the Scanning tunneling microscope developed by Gerd Binnig and Heinrich Rohrer and the discovery of Fullerene credited to researchers at Rice University and elsewhere. Milestones include the synthesis of Carbon nanotube by Sumio Iijima, commercialization efforts by companies like Intel Corporation and IBM, and policy initiatives including the National Nanotechnology Initiative in the United States. Major conferences and journals—organized by societies such as the American Chemical Society and Materials Research Society—have chronicled rapid expansion from basic science to applied engineering.

Nanotechnology enables innovations across sectors: in Electronics industry for Moore's law-driven scaling, advanced transistors at firms like Intel Corporation and TSMC, and memory technologies influenced by Samsung Electronics; in Pharmaceutical industry for targeted drug delivery platforms developed by companies such as Pfizer and Novartis; in Energy industry for next-generation Lithium-ion battery electrodes researched at Argonne National Laboratory and Toyota; in Aerospace for lightweight composites used by Boeing and Airbus; in Medical device development at centers like Mayo Clinic and Johns Hopkins Hospital. Other applications include water purification systems adopted by NGOs like Bill & Melinda Gates Foundation, coatings commercialized by 3M, and diagnostics pioneered by startups spun out of Harvard University and Caltech.

Key nanoscale materials include Graphene from University of Manchester research, Carbon nanotube arrays produced in laboratories at Rice University, Quantum dot semiconductors developed in groups at Bell Labs and University of California, Berkeley, metal nanoparticles studied by teams at Lawrence Berkeley National Laboratory, and self-assembled monolayers advanced by chemists at MIT. Fabrication techniques span top-down approaches like Electron beam lithography used in fabs at IMEC and TSMC, and bottom-up strategies such as Self-assembly (chemistry), Molecular beam epitaxy in facilities at Japan Science and Technology Agency, and chemical vapor deposition utilized by researchers at Stanford University. Characterization relies on instruments from Carl Zeiss AG, Bruker Corporation, and research centers such as National Institute of Standards and Technology.

Concerns about nanoscale materials’ toxicity have prompted studies at institutions like World Health Organization, Environmental Protection Agency (United States), National Institute for Occupational Safety and Health, and universities including University of California, Los Angeles and Johns Hopkins University. Research investigates inhalation risks, biodistribution, and ecotoxicology of particles such as Titanium dioxide nanoparticles and Carbon nanotube fibers. Regulatory responses include guidance documents and risk-assessment frameworks promulgated by agencies like European Chemicals Agency and Food and Drug Administration (United States). Remediation and monitoring efforts are pursued in collaboration with environmental NGOs and labs including Oak Ridge National Laboratory.

Ethical and governance debates involve stakeholders including United Nations Educational, Scientific and Cultural Organization, Organisation for Economic Co-operation and Development, civil society groups such as Greenpeace, and policy bodies like the European Commission. Topics include equity of access, dual-use concerns raised in dialogues involving Defense Advanced Research Projects Agency, intellectual property disputes adjudicated in courts and mediated by organizations like World Intellectual Property Organization, and workforce impacts discussed by labor groups in International Labour Organization. Public engagement initiatives at museums and universities—such as exhibitions at the Science Museum, London and outreach at Smithsonian Institution—seek to inform citizens and policymakers.
