Erasable Ink for 3D Printing

Laser-written Three-dimensional Microstructures Can Be Erased and Rewritten, if Desired – Very Important Paper Publication in Angewandte Chemie

3D printing by direct laser writing produces micrometer-sized structures with precisely defined properties. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a method to erase the ink used for 3D printing. In this way, the small structures of up to 100 nm in size can be erased and rewritten repeatedly. One nanometer corresponds to one millionth of a millimeter. This development opens up many new applications of 3D fabrication in biology or materials sciences, for instance.

Plants with Custom-fit Combined Traits

For the second time in succession, molecular biologist Professor Holger Puchta of Karlsruhe Institute of Technology (KIT) is awarded the renowned ERC Advanced Grant by the European Research Council for his research using molecular scissors in plants. The now funded CRISBREED project covers the simultaneous use of several molecular scissors, so-called CRISPR/Cas systems, to specifically modify genetic information and newly combine certain traits in crops.

Metal-organic Frameworks Used as Looms

Researchers of Karlsruhe Institute of Technology (KIT) have made major progress in the production of two-dimensional polymer-based materials. To produce cloths from monomolecular threads, the scientists used SURMOFs, i.e. surface-mounted metal-organic frameworks, developed by KIT. They inserted four-armed monomers, i.e. smaller molecular building blocks, into some SURMOF layers. Cross-linking of the monomers then resulted in textiles consisting of interwoven polymer threads. This work is now presented in Nature Communications. (DOI: 10.1038/ncomms14442)

Neurons Modulate the Growth of Blood Vessels

First Hampered, Then Released: Nerve cells regulate the density of blood vessel network dynamical-ly by fine modulation of signaling molecules.

A team of researchers at Karlsruhe Institute of Technology (KIT) shake at the foundations of a dogma of cell biology. By detailed series of experiments, they proved that blood vessel growth is modulated by neurons and not, as assumed so far, through a control mechanism of the vessel cells among each other. The results are groundbreaking for research into and treatment of vascular diseases, tumors, and neurodegenerative diseases. The study will be published in the prestigious journal Nature Communications.

Metal-organic Frameworks (MOFs) with Photoswitchable Azobenzene Molecules Enable Tunable Separation of Substance Mixtures – Publication in Nature Communications

Researchers of Karlsruhe Institute of Technology (KIT) and Universität Hannover developed novel membranes, whose selectivity can be switched dynamically with the help of light. For this purpose, azobenzene molecules were integrated into membranes made of metal-organic frameworks (MOFs). Depending on the irradiation wavelength, these azobenzene units in the MOFs adopt a stretched or angular form. In this way, it is possible to dynamically adjust the permeability of the membrane and the separation factor of gases or liquids. The results are reported in Nature Communications. (DOI:10.1038/ncomms13872)

Macromolecules: Light to Design Precision Polymers

For the First Time, Light Is Used to Specifically Design Defined Molecule Chains / Publication in Nature Communications .

Chemists of Karlsruhe Institute of Technology (KIT) have succeeded in specifically controlling the setup of precision polymers by light-induced chemical reactions. The new method allows for the precise, planned arrangement of the chain links, i.e. monomers, along polymer chains of standard length. The precisely structured macromolecules develop defined properties and may possibly be suited for use as storage systems of information or synthetic biomolecules. This novel synthesis reaction is now reported in open-access Nature Communications. (DOI: 10.1038/NCOMMS13672).
