Like a mixture of oil and water, lipid membranes separate into two liquid phases.

This thesis systematically analyzes the physical-chemistry of lipid-graphene interactions with the major objective of reconciliating the variety of results reported in the literature.

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

In augustus 2009 kwam Saeed Raoufmoghaddam uit Iran naar Leiden om zijn promotieonderzoek uit te voeren in de groep ‘Metals in Catalysis, Biomimetics & Inorganic Materials’. Korte tijd later werd hij gevolgd door zijn vrouw Azadeh Bahreman, die ook in Nederland een baan wilde zoeken. Zij kreeg een promotieplaats…

In 2050 moet de overstap naar nieuwe, duurzame energiebronnen zijn voltooid. Wetenschappers van de Universiteit Leiden verrichten vanuit diverse disciplines uniek onderzoek dat bijdraagt aan deze transitie en de reductie van CO2.

Het is onderzoekers voor het eerst gelukt grafeen op een stabiele laag vetten, ofwel lipiden, te plaatsen. Omringd door een beschermende laag van lipiden zou grafeen in het lichaam als een veelzijdige sensor kunnen dienen. De resultaten zijn de eerste stap naar zo’n omhulsel en zijn op 28 september…

Bij kanker groeien lichaamscellen ongecontroleerd. Het gedetailleerd in kaart brengen van hoe dit precies gebeurt maakt het mogelijk om efficiënte therapieën te ontwikkelen. Onderzoekers van het Leids Universitair Medisch Centrum (LUMC) en de Universiteit Leiden werken samen aan het vermeerderen van…

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

Heart failure is a major health care problem with high mortality.

Farmacoloog Walter Boiten ontwikkelde een nieuwe methode om de hoeveelheid vetten in iemands huid te kunnen bepalen. Met de methode testte hij de effecten van een nieuwe crème die hij ontwikkelde voor eczeempatiënten. De eerste resultaten zijn veelbelovend. Boiten promoveert op 15 januari.

Cardiovascular disease is the leading cause of death worldwide.

Atherosclerosis is the main underlying pathology of cardiovascular disease. Atherosclerosis is caused by an immune response which is directed against (modified) lipoproteins which accumulate in the vessel wall.
