Membrane proteins and membrane interactions of proteins are studied by spin label EPR. Intact, native membranes, vesicles of all sizes and nano-disks can be investigated, because the size of the object does not matter in EPR. Whereas solution NMR is limited to micelles (a few nm in diameter), by EPR…

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The current resurgence of whooping cough is alarming, and improved pertussis vaccines are thought to offer a solution. Outer membrane vesicle vaccines (omvPV) are potential vaccine candidates, but omvPV-induced humoral responses have not yet been characterized in detail.

Alexander Kros and co-workers describe how mesoporous silica nanoparticles (MSNs) are delivered into cells via membrane fusion thereby omitting endocytosis pathways. Fusion is induced by a pair of complementary coiled-coil lipopeptides inserted into the membrane of cells and in the bilayer of lipid-coated…

The skin barrier function is provided by the stratum corneum (SC). The lipids in the SC are composed of three lipid classes: ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs) which form two crystalline lamellar structures. In the present study, we investigate the effect of CER chain length…

The Computer Systems, Imagery & media (CSI) research programme performs research on methods and techniques for the design, implementation and application of advanced computer systems, in particular parallel, distributed and embedded computer systems.

The European Research Council (ERC) has awarded chemist Dr Alexander Kros a Starting Independent Researcher Grant of 1.4 million euro. He will be using the grant to study how molecules penetrate the natural barrier of a cell membrane. If his research is successful, it will in time bring about a revolution…

How can the transport of molecules in living cells help to target medicines at exactly the right place?

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

Task of the Computer Committee is to give advice, possibly unsolicited, on ICT matters to the Management Team of LIACS. This includes advice on ICT related policies of the faculty and university, procurement of computer and other machinery, and system administration.

The worldwide race to the quantum computer is in full swing. This computer can take on computing tasks that we can only dream of today, such as finding proteins that can be used as medicines in seconds flat. Leiden physicists have discovered how the Majorana particle can be used as a building block…

Computer programming is an essential skill for any researcher. It enables you to be self-sufficient in building research tools, processing data, visualizing research output, communicating research results, etc.

A high resolution, three dimensional view of a molecule provides detailed information that help elucidate its function: by knowing the exact arrangement of atoms in a molecule, we can understand disease, develop drugs to combat them and improve technology.

LIACS is partner in the project 'Stereotyping in Computer Science.' The project is a collaboration between multiple universities and the Dutch national expert organization on girls/women and science/technology (VHTO), which will investigate the stereotypes that children hold about computer scientist…

Natural Computing investigates algorithms and phenonema based on nature to create better and new computer science innovations.

We are becoming ever more dependent on automation systems in our daily lives. Computer Science is more than programming; you integrate maths and logic into the development of systems and solutions that can be applied in all fields - from business to healthcare.

Our goal is to develop usable, practical and meaningful Brain-Computer Interfaces to diagnose, restore, repair and enhance functions of the impaired brain.
