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…

This thesis describes the antimicrobial discovery strategy developed in our group, the den Hertog Group at the Hubrecht Institute. It includes a cultivation-based screening approach for novel antimicrobial agents from the source of fungi, and a bacterial time-lapse imaging approach for antimicrobial…

Photocatalysis has emerged as a powerful tool for enabling challenging transformations in organic synthesis. This thesis explores the development of several photocatalytic reactions designed to form carbon-heteroatom bonds from less-functionalized precursors.

This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

Endocannabinoids are lipid messengers that modulate various physiological functions by activating the cannabinoid CB1 and CB2 receptors. While the metabolism of endocannabinoids and their action at the CB receptors is fairly well studied, the molecular mechanisms governing their release and transport…

Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

The main goal of this thesis is to achieve advanced control of binding properties in bis-pyrrolic and macrocyclic pyrrolic receptors by light.

This thesis describes the use of an activity-based proteomics method to study the endocannabinoid system.
