Colloidal Concourse.

Scanning electron microscope image of silica-core/poly(n-isopropylacrylamid)-shell particles. The surface structuring was obtained by particle transfer using micro contact printing stamps with circular depressions. Afterwards the substrate was exposed to oxygen plasma to remove the soft polymer shell.

Thin Film Synthesis with Pulsed Laser Deposition.

Two lasers are used to deposit thin films on substrates. A CO2 laser impinges on the substrate on the left causing the substrate to emit blackbody radiation. A 266 nm pulse hits a target and creates the visible plume on the right. Chemistry under ultra-high vacuum conditions.

BZ Oscillating Reaction.

A photo of the color transition shown in the BZ oscillating reaction. The color changes between colourless and a light
brown are due to intermediate products formed in each of the reaction steps. In this particular experiment, sulfuric acid, malonic acid, potassium bromate, and manganese sulfate react together to produce bromine, carbon dioxide, and water by either a radical or non-radical process depending on the concentration of certain intermediate products.

Light-triggered protein assembly.

Shown is a modified microscope image of a glass surface functionalized with photoactivatable (“caged”) glutathione. During light irradiation inactive glutathione is photoconverted into its biological relevant form, which can be recognized by the red fluorescent labeled protein glutathione-S-transferase (GST). Total width of this image is 100 µm.
