Enhanced catalytic activity under non-equilibrium conditions

Rui Chen, Simona Neri
Nat. Nanotech. 2020, 15, 868-874 (link)

A diffusion-reaction system in a gel matrix shows that concentration gradients in a hydrogel can lead to an overall enhanced catalytic activity.

We have developed a hydrogel that displays an enhanced catalytic activity when irradiated locally with UV-light.

The improved performance of materials under non-equilibrium conditions is an important stimulus to continue the exploration of complex systems that operate using life-like principles.

RESEARCH

SYSTEMS CHEMISTRY

Chemists have so far approached the understanding of biology by reducing complex events to simple reactions and interactions. However, despite decades of intense biomimetic research, it is currently still unclear which conditions are required for a mixture of chemicals to acquire the ability to grow, communicate, move, evolve... The key point is that these so-called emerging properties cannot be traced back to a single molecule, but, instead, are the product of an ensemble of molecules. Following a bottom-up approach, systems chemistry aims at understanding how properties emerge from molecular networks.

DRIVEN SELF-ASSEMBLY

Supramolecular chemistry is rapidly moving into new territory in which the composition of a dynamic system is no longer determined by the relative thermodynamic stabilities of the components, but by the capacity of the components to populate high-energy states exploiting energy-dissipating processes. This capacity implies that such systems may store and transfer energy, which would bring us closer to implementing the marvelous properties of living systems in synthetic ones.

MULTIVALENT NANOSYSTEMS

Molecular recognition processes and catalysis in Nature involve large and complex structures such as antibodies and enzymes. The multipoint interactions that develop between host and guest permit binding to occur with high affinity and selectivity. Also, large structures facilitate the installment of regulatory mechanisms for instance through the formation of multicomponent complexes or the contemporary binding of co-factors. Synthetic systems that match up to the size and complexity of proteins could enable such properties in a nonbiological context or, alternatively, could be integrated in biological networks.

Leonard J. Prins (1974, Netherlands) is full professor of Organic Chemistry in the Department of Chemical Sciences at the University of Padova, Italy. He obtained his PhD-degree from the University of Twente, Netherlands with prof. David Reinhoudt in 2001. After postdoctoral research with prof. Peter Dervan at Caltech, Pasadena, USA and prof. Giulia Licini at the University of Padova, Italy he started his independent career in 2004 in Padova. He has been awarded the 2001 Backer-prize by the Royal Dutch Chemical Society and the 2009 Ciamician-medal by the Italian Chemical Society. In 2009 he was the recipient of an ERC Starting Grant. His current research interests are the application of multivalent systems for catalysis, chemical network reactivity, and chemical fuel-driven self-assembly.
