17-2020-IMT PhD Position on Structured light for precise control over crystallization of organic molecules

Vacancy to be filled from: 01.07.2020


We are seeking applications from candidates for a 3 year PhD studentship in the area of light-assisted crystallization of proteins, to be co-supervised by Prof. Jan Korvink and visiting Humboldt Fellow Andrew Forbes, together with IMT group leaders Dr. Neil MacKinnon and Dr. Ian Howard.

Recently it has been shown that transitions from disorder to order of solvated molecules can be driven by coherent light. By localizing the metastable zone at the edge of a focal spot, control over the organic crystallization process is enabled, removing the strong dependence on super-saturation for the nucleation of macro-molecular crystals, see Suzuki et al 2018, Control of Organic Crystal Shape by Femtosecond Laser Ablation, Crystal Growth & Design 18 (9) 4807-5712.

In the current project we want to build upon these initial discoveries and develop greater control over this light-induced crystallization process through the use of structured light, i.e., light tailored in 3D and in all its degrees of freedom. Through these developments, our goal is to achieve unprecedented control over the creation of crystals of arbitrary shape. The vision is to develop a light-induced crystallization apparatus to effectively "3D print" functional organic crystals on the microscale, using structured light to structure matter.  Ultimately, such an ability to design and produce arbitrarily micro-structured functional organic crystals would provide a much-desired bridging technology between micro electro-mechanical systems and the biological world. Applications would include, but are not limited to, medical sensing and therapeutics. The successful candidate will work at the Institute of Microstructure Technology, with its excellent micro and nano structuring infrastructure, will be admitted to the Karlsruhe School of Optics and Photonics, and will be registered in the Faculty of Mechanical Engineering.
