This image shows the three dimensional structure of glial fibrillary acidic protein in a human glioblastoma astrocytoma cell. The colour represents the axial position. The image is 15x15x1 µm. This image is obtained using super resolution microscopy. Here the blinking of fluorescent molecules is used to measure only the signal originating from a single molecule. A cylindrical lens creates an astigmatism that allowed us to obtain both lateral and axial position of the molecule. - Rolf Harkes

The picture shows a microscope image of micrometer-sized flowers self-assembled from silica particles equipped with sticky “DNA-glue". The core of the flowers are 1 micrometer-sized silica particles functionalized with a DNA strand with a green dye. The petals of the flowers consist of 2 micrometer-sized particles, containing the complementary DNA strand with a red dye - Indrani Chakraborty

The magnetic field in a plasma can form a stable structure where the field lines lie on donut-shaped magnetic surfaces. When you give the structure a kick, perturb it, some of the donuts break apart into tubes, called magnetic islands. This image shows for each magnetic surface how quickly the field lines wrap around the torus. When the field lines close the surfaces are likely to break up, as you can see in the image, where 2,3 islands an 5,8 islands can be seen - Tobias de Jong

Koolstof ‘nanotrees’ in verschillende grootte en stage van groei. De nanotrees groeien in een random vorm, onder invloed van de hoog-voltage electronenbundel (200 kV) van de Transmissie Electronen Microscoop, uit een plakje puur koolstof. Het puur koolstof is zichtbaar als de donkere cirkel in het midden, en ligt op een 10 nm dunne, amorfe SiN (silicon nitride) window. Koolstof nanotrees zijn een vorm van koolstof nanotubes, die zich vertakken in 3 dimensies tijdens de groei. - Marien…

Still life of diffraction patterns created by KOH etched square holes in Gold on Silicon Nitride. Image taken by an optical microscope with black and white sensor. Kandinsky would be proud! https://upload.wikimedia.org/wikipedia/commons/f/f0/Vassily_Kandinsky,_1923_-_Circles_in_a_Circle.jpg - Maarten Leeuwenhoek

This electron microscope image is a fitting portrayal of what I, as an experimentalist, often find somewhat comparable with crime scene investigation. The victim in this case was an unsuccessful attempt to develop nano-stencils for fabricating magnetic pillar hybrids. The stencil is created by dissolving SiO2 with acid through an opening in a platinum mask. Ideally this should have formed a void in SiO2 with the Pt layer suspended above, which is not seen here - Kaveh Lahabi

Scanning electron microscopy image of micron-sized particles, so-called colloids, with a smiley face on one side of the sphere. The particles are made by solidifying soft spheres, which induces buckling of the outside of the shell resulting in dents. In this particular case, the dents form smiley faces on al particles! These particles are used in self-assembly experiments to obtain larger structures with novel physical properties - Vera Meester

Lipid membranes mediate a force between membrane proteins. In this confocal microscopy image, six spherical lipid membranes together with many 0.001 mm sized particles can be seen. Several of these particles are attached to the membranes: these particles attract each other through the membrane deformation they induce - Casper van der Wel

Einstein-de Sitter space is named after its discoverers and describes a universe that contains only pressureless matter, without spatial curvature and without a cosmological constant. Small perturbations in the pressureless matter clump together because of gravity and form a random cosmic web. Creation of such universes on a computer is important for obtaining a better understanding of the theory of gravity and the origin of structure. - Wessel Valkenburg

Technological advances call for functional design. As a result, materials with unusual properties are in increasing demand. So-called metamaterials behave very differently from traditional substances such as wood or concrete. - Anne Meeussen

Het gaat hier om een microocube, liggend tussen Cobalt-nanoparticles. De nanoparticles zijn wat ronder van vorm, met verschillende oriëntaties, terwijl we de microcube hier precies edge-on zien. Door de hoge resolutie Trasmissie Electronen Microscoop (HRTEM) kunnen we gemakkelijk de deeltjes op atomaire schaal bekijken. - Marien Bremmer

The band structure of a material is a map of which states are allowed for its electrons. Here you see the unoccupied bands of boron nitride - a two-dimensional insulator that is the most promising substrate for future electronics. Its bands are revealed by angle-resolved reflected-electron spectroscopy (ARRES) - new technique developed in Leiden to study novel nanomaterials - Johannes Jobst

Optical microscope image of a detection chips covered with silicon nitride used for Magnetic Resonance Force Microscopy (MRFM), a technique in which we detect signals from a small number of spins using a mechanical resonator. The horizontal line is the RF-wire, used for the generation of magnetic fields to manipulate the spins in the sample, while the two small squares  in the center are used to inductively detect the motion of the resonator - Martin de Wit

Low-energy electron microscopy (LEEM) images of the growth of single atomic layers are often beautiful works of abstract art. In fact, the resemblence with the works of renowned Dutch masters is so remarkable, it is almost as if the artists were prescient of today's technology. - Jaap Kautz

Solar cell, the interface between photons and electrons. In the warm colors of this picture you find a lot about my research. It contains the darkness of an optics lab, only broken by a small white lamp used for sample inspection. You can guess the presence of a microscope objective, which focuses the laser to probe the sample, and see two electrical contacts necessary to collect electrons. Homemade design and FMD work were also necessary to conveniently mount the sample. - Flavio Mariani
