Contents

Early life and education

Katsonis was born in Vienna. [1] She grew up in Orsay, in Paris Region. She is half French and half Greek. She studied chemical engineering at the Chimie ParisTech, before moving to Ecole Normal Superieure for her graduate studies with Ludovic Jullien. Katsonis earned her doctoral degree at the Pierre and Marie Curie University. She worked on nanoscale probes of two dimensional molecular self-assemblies with Denis Fichou. [2] She joined the research group of Ben Feringa at the University of Groningen, where she worked on self-assembly of motors and switches. [3] Whilst at Groningen Katsonis developed scanning probe microscopy for the determination of molecular chirality. [4]

Research and career

Katsonis joined the Centre National de la Recherche Scientifique (CNRS) in 2007 and started to work on light-responsive chiral liquid crystals. [3] She was made a Group Leader at the University of Groningen and held a visiting position at KU Leuven. In 2012 she was awarded a Royal Society International Exchange grant to work with Steve Fletcher on light responsive polymers. [5] [6] Katsonis proposed the materials could be used for microfluidics or soft robotics. [5] Her research is inspired by nature, where helical structures are often created for movement. [7]

She moved to the University of Twente in 2013, and was promoted to Professor in 2016. [3] [7] She returned to the University of Groningen as Professor of Active Molecular Systems in 2020. Katsonis has worked on squishy light responsive materials, which can convert light energy into mechanical work. She demonstrated that it is possible to switch between left and right-handed helixes in cholesteric liquid crystals using light. [8] She has also showed that it is possible to use twisted liquid crystals as organising templates to design self-assemblies of superparamagnetic nanoparticles. [9] In 2017 she was awarded a European Research Council Consolidator Grant in nanotechnology. [10] Her recent work has been concerned with unravelling the molecular origin of purposeful motion, both in space and time at the nanoscale.

<span class="mw-page-title-main">Liquid crystal</span> State of matter with properties of both conventional liquids and crystals

Liquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal can flow like a liquid, but its molecules may be oriented in a common direction as in a solid. There are many types of LC phases, which can be distinguished by their optical properties. The contrasting textures arise due to molecules within one area of material ("domain") being oriented in the same direction but different areas having different orientations. An LC material may not always be in an LC state of matter.

<span class="mw-page-title-main">Enantiomer</span> Stereoisomers that are nonsuperposable mirror images of each other

In chemistry, an enantiomer – also called optical isomer, antipode, or optical antipode – is one of two stereoisomers that are nonsuperposable onto their own mirror image. Enantiomers of each other are much like one's right and left hands; without mirroring one of them, hands cannot be superposed onto each other. It is solely a relationship of chirality and the permanent three-dimensional relationships among molecules or other chemical structures: no amount of re-orientiation of a molecule as a whole or conformational change converts one chemical into its enantiomer. Chemical structures with chirality rotate plane-polarized light. A mixture of equal amounts of each enantiomer, a racemic mixture or a racemate, does not rotate light.

<span class="mw-page-title-main">Molecular machine</span> Molecular-scale artificial or biological device

Molecular machines are a class of molecules typically described as an assembly of a discrete number of molecular components intended to produce mechanical movements in response to specific stimuli, mimicking macromolecular devices such as switches and motors. Naturally occurring or biological molecular machines are responsible for vital living processes such as DNA replication and ATP synthesis. Kinesins and ribosomes are examples of molecular machines, and they often take the form of multi-protein complexes. For the last several decades, scientists have attempted, with varying degrees of success, to miniaturize machines found in the macroscopic world. The first example of an artificial molecular machine (AMM) was reported in 1994, featuring a rotaxane with a ring and two different possible binding sites. In 2016 the Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa for the design and synthesis of molecular machines.

<span class="mw-page-title-main">Nanocar</span> Chemical compound

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.

<span class="mw-page-title-main">Synthetic molecular motor</span> Man-made molecular machines

Synthetic molecular motors are molecular machines capable of continuous directional rotation under an energy input. Although the term "molecular motor" has traditionally referred to a naturally occurring protein that induces motion, some groups also use the term when referring to non-biological, non-peptide synthetic motors. Many chemists are pursuing the synthesis of such molecular motors.

A photoswitch is a type of molecule that can change its structural geometry and chemical properties upon irradiation with electromagnetic radiation. Although often used interchangeably with the term molecular machine, a switch does not perform work upon a change in its shape whereas a machine does. However, photochromic compounds are the necessary building blocks for light driven molecular motors and machines. Upon irradiation with light, photoisomerization about double bonds in the molecule can lead to changes in the cis- or trans- configuration. These photochromic molecules are being considered for a range of applications.

A molecular switch is a molecule that can be reversibly shifted between two or more stable states. The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric current, microenvironment, or in the presence of ions and other ligands. In some cases, a combination of stimuli is required. The oldest forms of synthetic molecular switches are pH indicators, which display distinct colors as a function of pH. Currently synthetic molecular switches are of interest in the field of nanotechnology for application in molecular computers or responsive drug delivery systems. Molecular switches are also important in biology because many biological functions are based on it, for instance allosteric regulation and vision. They are also one of the simplest examples of molecular machines.

A blue phase mode LCD is a liquid crystal display (LCD) technology that uses highly twisted cholesteric phases in a blue phase. It was first proposed in 2007 to obtain a better display of moving images with, for example, frame rates of 100–120 Hz to improve the temporal response of LCDs. This operational mode for LCDs also does not require anisotropic alignment layers and thus theoretically simplifies the LCD manufacturing process.

A liquid-crystal laser is a laser that uses a liquid crystal as the resonator cavity, allowing selection of emission wavelength and polarization from the active laser medium. The lasing medium is usually a dye doped into the liquid crystal. Liquid-crystal lasers are comparable in size to diode lasers, but provide the continuous wide spectrum tunability of dye lasers while maintaining a large coherence area. The tuning range is typically several tens of nanometers. Self-organization at micrometer scales reduces manufacturing complexity compared to using layered photonic metamaterials. Operation may be either in continuous wave mode or in pulsed mode.
