James Kazimierz Gimzewski is a Scottish physicist of Polish descent who pioneered research on electrical contacts with single atoms and molecules and light emission using scanning tunneling microscopy (STM). [3]
Gimzewski was born in Glasgow to Polish World War II war veteran Edmund Gimzewski. He earned his undergraduate degree in 1974 and PhD in 1977 from the University of Strathclyde in Glasgow. Until February 2001, he was a group leader at the IBM Zurich Research Laboratory, where he was involved in nanoscale science since 1983. Currently, he is a Professor in the Department of Chemistry and Biochemistry at UCLA, where he conducts research and advises graduate students in his PicoLab. He is also the faculty director of the Nano & Pico Characterization core lab at the California NanoSystems Institute at UCLA. [1] [2]
He pioneered research on electrical contact with single atoms and molecules, light emission and molecular imaging using STM. His accomplishments include the first STM-manipulation of molecules at room temperature, the realization of molecular abacus using buckyballs (C60), the discovery of single molecule rotors and the development of nanomechanical sensors based on nanotechnology, which explore the ultimate limits of sensitivity and measurement.
Recently [ when? ], he discovered a new method to synthesize carbon nanotubes more regular in diameter and length. His current interests within CNSI are in the Nanoarchitectonics of molecular systems and molecular and biomolecular machines, in particular those with quantum mechanical possibilities for information processing.
Recently [ when? ], he has undertaken research in biophysics, which he calls sonocytology. With UCLA graduate student Andrew Pelling, Gimzewski published sonocytology's debut report in the August 2004 issue of Science magazine. In the sonocytology studies, a Bioscope AFM (atomic force microscope) was modified to be able to detect the vibrations of the cell wall of a living cell. These vibrations, once amplified using computer software, created audible sound, and it was discovered that cancerous cells emit a slightly different sound than healthy cells do. Gimzewski and Pelling hope that sonocytology may someday have applications in early cancer detection and diagnosis.
In 2001 Gimzewski became Fellow of the Royal Academy of Engineering, [4] and in 2009 was elected Fellow of the Royal Society, [5] the highest award in Britain for excellence in Science. He received the 1997 Feynman Prize in Nanotechnology, [6] the 1997 The Discover Award for Emerging Fields, the 1998 “Wired 25” Award from Wired magazine and the Institute of Physics 2001 Duddell Medal and Prize for his work in nanoscale science. He holds two IBM “Outstanding Innovation Awards”, and is a Fellow of the Institute of Physics and a Chartered Physicist. Gimzewski is a member of scientific boards of Carbon Nanotechnologies, Inc. and Veeco Instruments. [1] [2]
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter. This definition of nanotechnology includes all types of research and technologies that deal with these special properties. It is common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to research and applications whose common trait is scale. An earlier understanding of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabricating macroscale products, now referred to as molecular nanotechnology.
Nanoengineering is the practice of engineering on the nanoscale. It derives its name from the nanometre, a unit of measurement equalling one billionth of a meter.
Brownian motors are nanoscale or molecular machines that use chemical reactions to generate directed motion in space. The theory behind Brownian motors relies on the phenomenon of Brownian motion, random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid.
Nanoid robotics, or for short, nanorobotics or nanobotics, is an emerging technology field creating machines or robots, which are called nanorobots or simply nanobots, whose components are at or near the scale of a nanometer. More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots with devices ranging in size from 0.1 to 10 micrometres and constructed of nanoscale or molecular components. The terms nanobot, nanoid, nanite, nanomachine and nanomite have also been used to describe such devices currently under research and development.

He has been a fellow of St John's College, Cambridge, since 1986 and started his career in nanotechnology at IBM Research, where he was part of the team that developed one of the first scanning tunnelling microscopes. He was served as the Master of St Catharine's College, Cambridge and took up office from 2016 to 2023.
A nanomotor is a molecular or nanoscale device capable of converting energy into movement. It can typically generate forces on the order of piconewtons.
Sir James Fraser Stoddart is a British-American chemist who is Chair Professor in Chemistry at the University of Hong Kong. He has also been Board of Trustees Professor of Chemistry and head of the Stoddart Mechanostereochemistry Group in the Department of Chemistry at Northwestern University in the United States. He works in the area of supramolecular chemistry and nanotechnology. Stoddart has developed highly efficient syntheses of mechanically-interlocked molecular architectures such as molecular Borromean rings, catenanes and rotaxanes utilising molecular recognition and molecular self-assembly processes. He has demonstrated that these topologies can be employed as molecular switches. His group has even applied these structures in the fabrication of nanoelectronic devices and nanoelectromechanical systems (NEMS). His efforts have been recognized by numerous awards, including the 2007 King Faisal International Prize in Science. He shared the Nobel Prize in Chemistry together with Ben Feringa and Jean-Pierre Sauvage in 2016 for the design and synthesis of molecular machines.
The nanocar is a molecule designed in 2005 at Rice University by a group headed by Professor James Tour. Despite the name, the original nanocar does not contain a molecular motor, hence, it is not really a car. Rather, it was designed to answer the question of how fullerenes move about on metal surfaces; specifically, whether they roll or slide.
A nano-abacus is a nano-sized abacus that performs basic arithmetic computations using various forms of nanotechnology including photonics and lateral mechanical stimulation of molecular motion with a scanning tunneling microscope (STM) tip by repulsion. The nano-abacus has the potential to be used in a variety of nanotechnological inventions such as the nano-computer.
The history of nanotechnology traces the development of the concepts and experimental work falling under the broad category of nanotechnology. Although nanotechnology is a relatively recent development in scientific research, the development of its central concepts happened over a longer period of time. The emergence of nanotechnology in the 1980s was caused by the convergence of experimental advances such as the invention of the scanning tunneling microscope in 1981 and the discovery of fullerenes in 1985, with the elucidation and popularization of a conceptual framework for the goals of nanotechnology beginning with the 1986 publication of the book Engines of Creation. The field was subject to growing public awareness and controversy in the early 2000s, with prominent debates about both its potential implications as well as the feasibility of the applications envisioned by advocates of molecular nanotechnology, and with governments moving to promote and fund research into nanotechnology. The early 2000s also saw the beginnings of commercial applications of nanotechnology, although these were limited to bulk applications of nanomaterials rather than the transformative applications envisioned by the field.
The Feynman Prize in Nanotechnology is an award given by the Foresight Institute for significant advances in nanotechnology. Two prizes are awarded annually, in the categories of experimental and theoretical work. There is also a separate challenge award for making a nanoscale robotic arm and 8-bit adder.
