The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

During adolescence, mood disorder onset peaks. Mood variability is associated with negative mental health outcomes, so understanding biological factors that might be associated with mood variability, such as sleep and structural brain development, could elucidate the mechanisms underlying mood and anxiety…

Does Artifical Light at Night (ALAN) disrupt seasonal physiological and behavioral patterns in migrating freshwater fish?

This work has described synthetic strategies towards well-defined structures resembling capsular polysaccharide (CPS) fragments, CPS mimics, teichoic acid (TA) fragments as well as a third-generation ring-closing tandem metathesis (RCM) linker to better exploit the potential of automated synthesis.

Can we establish a new quality control system for herbal medicines that is based on bioactivity rather than a few abundant chemicals?

Supervisor: Gerard van Westen

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

Glycosidases are essential in fundamental biological processes and are responsible for the degradation of most (oligo)saccharides, glycolipids and glycoproteins.

Where did species survive the cold cycles of the current Ice Age?

Lipid signaling is an essential biological event/process in a plethora of pathophysiological conditions. The underlying idea of this thesis is that many of the roles and the complex interplay of the individual signaling lipids in inflammatory processes and related conditions in health and disease is…

The goal of target discovery is to identify and validate proteins and biological pathways that are involved in the disease process. Modulating these target proteins and pathways with small molecules, therapeutic proteins or other biomolecules (e.g. mRNA) could deliver an effective and safe drug or v…

This Thesis focuses on the design and synthesis of ADP-ribosylated compounds that can be applied in biological studies.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

The Biological- and Soft-Matter Physics specialisation is an excellent preparation for pursuing a PhD degree in physics.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

Biotherapeutics or biologics, such as proteins, peptides, and nucleic acids, comprise an increasing share of the pharmaceutical market, whilst offering new therapies for difficult-to-treat diseases. Most notable is their contribution to the vaccination efforts during the COVID-19 pandemic. In most cases,…

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Nadine Raaphorst, university lecturer at the Institute of Public Administration, has been awarded a Veni-subisidy from science financier NWO. This grant of up to 250,000 euros will enable her to set up her own research in the coming years. Raaphorst's research is about consistent decision-making by…

Many biological processes occur by biomolecules coming together and organizing into specific clusters without being bound to each other. These interactions range from clustering, transiently interacting (kiss and run), or assembling to multimeric units that can only function in conjunction. The hydrogen…

Our research is aimed at a smoother and speedier transition from preclinical research to pharmacological interventions, and the delivery of drugs in the human body by use of small molecules and biologics.

Within the Chinese medicine, more than 80% of the constituents of the preparations are derived from plants. Like any other organism, plants are constantly interacting with their changing and often harsh environment during the various phases of their life cycle.

In this thesis an activity-based probe was discovered that could visualize the activity of PLAATs. With an optimized gel-based ABPP assay in hand, screening of a compound library led to the discovery of alpha-ketoamides as a hit for PLAAT3.

Ceramides (CERs), cholesterol, and free fatty acids (FFAs) are the main lipid classes in human stratum corneum (SC, outermost skin layer), but no studies report on the detailed analysis of these classes in a single platform.

With the powerful electron microscopes at NeCEN we study abnormalities in cells of blood vessels in cardiovascular disease, the interaction between pathogens and hosts in infectious diseases, molecular processes that cause cancer and the interaction between drugs and target proteins. Drug development…

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

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.

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.
