Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Molecular Physiology is a research group at the Leiden Institute of Chemistry dedicated to the design, synthesis and application of chemical tools to study important biological and biomedical questions. The group is headed by Prof. Dr. Mario van der Stelt and includes the research lines of Assistant…

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

A thorough understanding of the workings of the cell underly the understanding of disease at the molecular level. Revealing the principles of biochemical processes helps to identify the targets for the development of new drugs. At the Leiden Institute of Chemistry (LIC), we believe that the application…

Chemistry is all around us: from nutrition and smartphones to medicine. The field is developing rapidly, as the world population continues to grow and resources become scarce. MST will educate you on the basics of working towards a clean and healthy world.

Currently, several successful vaccines are available. However, for pathogens with a highly variable genetic composition, and for which serum IgG antibodies are not a useful correlate of protection, effective vaccines are yet to be developed.

In this research group, headed by Laura Heitman, novel receptor concepts in drug discovery are studied, aiming to increase the effectivity of medicines. Many drugs act via so-called G protein-coupled receptors (GPCRs) and therefore our research is mainly focused on understanding and improving drug-receptor…

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

The master's specialisation Molecular, Cellular and Organismal Biology at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

How do you fit two meters of DNA in a tiny compartment and at the same time are able to access the right parts of it at the right times?

Chronic pain, nausea or vomiting due to chemotherapy. If you suffer from such ailments, medicinal cannabis can be a godsend. Though a downside is that it can make patients high. Therefore, Leiden researchers from the Oncode Institute are investigating alternatives that do not make you high. In Nature…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

This thesis provides an overview of the development of the Pair Configuration to Molecular Activity Coefficient (PAC-MAC) model.

Phosphorylation affects all four major biomolecules – proteins, lipids, carbohydrates and nucleic acids – and plays a pivotal role in the most fundamental cellular functions.

Adverse drug reactions (ADRs) remain one of the major reasons for patient mortality and (early) drug withdrawal. Currently, different in vivo and in vitro models are used to assess the toxic potential of drugs in the pre-clinical phase. Unfortunately, the predictive value of this model does not fit…

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Dit proefschrift beschrijft een collectie aan alternatieve strategieën voor het begrijpen, ontwerpen en toepassen van lipide nanosystemen, waarin de rol van de bio-nano interacties centraal staan. In het bijzonder wordt gekeken naar de interactie van RNA-lipide nanosystemen, bekend van de toepassing…

The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.
