Division I - Biology, Chemistry, and Process Engineering

Division I comprises twenty KIT institutes, the KIT Department of Chemistry and Biosciences and the KIT Department of Chemical and Process Engineering as well as the Helmholtz Programme BioInterfaces.


Since January 1, 2014, Professor Dr. Doris Wedlich has been Head of Division I.

Growth Mechanism of Fungi Decoded

Fungal Cells Do not Grow by Division, but Extend Almost Infinitely – Video Sequence Illustrates Growth
[2017_068_Wachstumsmechanismus der Pilze entschluesselt_72dpi]
Fungi grow with tubular cells extending by kilometers. Growth takes place exclusively at the tip. Researchers of Karlsruhe Institute of Technology (KIT) have now found out how this works: Construction materials are transported on rails through the fungal cells and used at their outermost tip. Calcium concentration at the end of the cell defines when this happens. This is reported by the scientists in the Proceedings of the National Academy of Sciences USA (PNAS).

Water Droplets as Miniaturized Test Tubes

New Laboratory Technology Makes Search for Active Substances Less Expensive – Water Droplets Self-arrange and Pipetting Robots Are No Longer Required.

Modern laboratory technology cannot only help develop new medicine, but also make quicker diagnoses of higher precision. Scientists of Karlsruhe Institute of Technology (KIT) have now developed laboratory equipment that facilitates the search for active substances and the examination of cell samples. Thus, costs are reduced by a factor of up to one hundred.

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.
