Call for 2024 Chinese Applicants Running for a CSC Fellowship :
IMDEA Nanoscience (https://www.nanociencia.imdea.org/)
Systems Chemistry Laboratory (www.hermanslab.com)
Supervising scientist: Professor Thomas M. HERMANS (Thomas.hermans@imdea.org)
Research Field: Out-of-equilibrium supramolecular self-assembly
Keywords: Systems Chemistry, Self-assembly, Nonequilibrium systems, Supramolecular polymers
Research Area:
Looking at nature, we see that living materials with biological functionality, such as the actin or microtubule (MT)
cytoskeletal network, achieve dynamics as well as supramolecular structures with the same protein building
blocks. In other words, the components can assemble, but also react (i.e., tubulin is also an enzyme that hydrolyses
guanosine triphosphate GTP), which in turn affects the assemblies. In this way, living systems use chemical fuels
(e.g., GTP) and self-assembly to create a built-in chemomechanical interaction. Moreover, such networks operate
in sustained out-of-equilibrium states at the onset of oscillations,1–3 which results in rapid response and adaptivity.
We have recently shown 4–5 reaction cycles in solution and gels, where interesting new behaviors were found,
such as supramolecular size oscillations, traveling polymerization, or transient disassembly. We hope such reaction
cycles form the basis of new life-like materials where material properties are fuel (and waste) dependent. The PhD
project involves the synthesis of new microtubule like structures based on all artificial small molecules that can be
controlled by chemical fuels and/or light.
