The Supramolecular & Biomaterials Chemistry group comprises the PIs Alexander Kros, Roxanne Kieltyka, Gregory Schneider and Sander Wezenberg, and is active in the field of self-assembly of amphiphilic peptides and applying them in supramolecular chemistry.

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

A new type of tripodal squaramide-based supramolecular hydrogels is developed and studied.

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

Bet v1, the major allergen in birch pollen, is one of the main causes of allergies such as asthma and rhino-conjunctivitis. Additionally it is the main cause of birch pollen allergy in humans.

PhD student Willem Noteborn has investigated supramolecular structures. These can be useful for the loading of medicines and signalling molecules regarding, for example, cellular differentiation. In his thesis, he describes the functioning of these structures.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Research at the SBC group is comprised of the following research themes:

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

Promoter: J.G.E.M.Fraaije, Co-promotor: A. Kros

Presenters will be expected to give a proper introduction of the project and describe their aims in a clear and concise manner. Progress and problems will be addressed to evoke a discussion. Undergraduate students are also supposed to present their work when their daily supervisor is scheduled.

Chemist Roxanne Kieltyka has received an ERC Starting Grant of 2 million euros. In her lab, she creates gels that mimic the instructive material that supports cells in our body. With the grant, she aims to make these gels stiff and tough, and to create a bio-printed miniature heart ventricle.

Although Sander Wezenberg just started working in Leiden in March this year, he already managed to win a Vidi grant from NWO. Inspired by nature, Wezenberg wants to bring synthetic molecules to life and teach them to communicate. But who exactly is Wezenberg and what drives him?

With its instalment in 2022, the Kroese-Duijsters Symposium will provide a platform for interaction between researchers from different fields and in different career stages, from doctoral students to world-leading professors.

FitDis! is designed to ease the determination of binding energy and oligomeric state of coiled coil peptides. It allows direct fitting of concentration dependent thermal peptide unfolding curves measured for instance by CD–spectroscopy.

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

The Leiden Institute of Chemistry is proud to offer the “Leiden Chemical Biology Lectures”. This lecture series aims to bring excellent researchers in the field of chemical biology to our university, and to expose our students to top science conducted in this area.

How does the photoregulation mechanism work in detail?

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables, water and energy.…
