Molecular information processing in self‐organised networks - Dr. Peter Korevaar (RU)
Living matter is entirely driven by chemistry, and acts as a “chemical computer” where chemical signals are exchanged and processed to direct the spontaneous build‐up of organisms. In synthetic materials, this enables fundamentally new potential where functions – motion, growth, shape‐transformation – are directed via molecular information processing, rather than traditional electronics. The researchers will demonstrate this principle in networks of self‐assembling wires, which spontaneously grow, transfer chemical signals between sender and receiver agents and thereby – via a cascade of input‐output steps – direct the self‐organization of patterns. This might lead to e.g. neuromorphic sensors or self‐adapting lab‐on‐a‐chip applications.
The research grant covers two 4-yr PhD position as well as equipment costs. The vacancy for the first PhD position can be found here

Emergent organization of connectivity in active matter networks - Dr. Peter Korevaar (RU)
Most synthetic materials are inactive and limited to just one function, in contrast to living matter which can adapt itself to changing circumstances. The researchers will, by using molecular self-assembly and chemical reactions, mimic this behaviour in networks of wires that spontaneously grow, organize, and adapt to changes in their environment. This will provide new insights into the emergence of life-like behaviour from simple molecular building blocks. Furthermore, self-organizing networks provide unprecedented potential in applications where connections (e.g. wires or channels) can reorganize themselves, for example in lab-on-a-chip technologies where the right connections emerge spontaneously. The research grant covers one 4-yr PhD position as well as equipment costs.

ChemRxiv pre-print on Self-organization of Myelin networks.
[12 October 2021] We posted our Mitch' newest pre-print on the self-organization of our myelin-networks at air-water interfaces. Typically, self-organization relies on the emergence of gradients, e.g. in concentration, surface tension, or meniscus curvature at air-water interfaces. However, the spreading of these gradients is non-directional. Mechanisms by which self-organization is mediated through specific connections, where some elements attract each other while others are repelled, are seldom reported. In this new manuscript, we show that the directional growth of our myelin filaments enables directional attraction in self-organizing systems at air-water interfaces: the self-assembled filaments establish connections that can selectively attract floating droplets via Marangoni and elastocapillary effects. Read the pre-print here.

Publication on non-equilibrium signal integration in hydrogels in Nature Communications
[20 January 2020] Together with the group of Joanna Aizenberg at Harvard, and Nadir Kaplan (Virginia Tech), we published a paper in Nature Communications which introduces the idea that hydrogels, previously just thought to shrink and swell in time with the presence or absence of a specific stimulus, can generate fascinating new classes of non-equilibrium responses. Thereby, hydrogels can act as complex chemical signal integrators – a universal feature of living materials but currently absent from synthetic systems. The paper can be found here.

Chemical communication strategies in life-like materials - Dr. Peter Korevaar (RU)
Living matter has many fascinating properties that offer a great source of inspiration to the development of functional materials. A particular interesting feature of living matter is the capability to selectively pick-up stimuli from its environment and process this information into appropriate behaviour. In our Life-like Materials group, we try to implement these life-like properties into synthetic materials, and thereby provide new functionalities to a next generation of smart materials.
The research supported by this NWO Grant focusses on chemical communication strategies in life-like materials. Like electric signals are transported through wires and transistors on a chip, we will develop a chemical system that grows dynamic wires on a substrate, enabling the transfer of chemical stimuli from A to B. By combining molecular self-assembly with physicochemical phenomena as diffusion and surface tension, these wires can grow and disassemble again, resulting – ultimately – into autonomous systems combining transfer of information to logic operations with input of multiple chemical stimuli.
This 332.6 k€ research grant covers one 4-yr PhD project as well as equipment costs.

Synthetic materials in life-like motion - Dr. Peter Korevaar (RU)
The assembly of molecular building blocks into dynamic materials that grow, move and self-regulate is one of the most fascinating processes in living matter. The researchers will develop new strategies to apply the underlying principles in artificial, “smart” materials that display controlled motions and exert forces at the micro-scale.
