The goal of this thesis was to study silica and gold nanoparticles from synthesis to characterization to biomedical application. Nanoparticles (NPs) are typically defined as materials with at least one of its dimension in the range of 1 nm to 100 nm. In this way the NP will behave like a molecule and like bulk material. NPs have unique electronic, optical, magnetic and catalytic properties. Because of these unique properties, nanoparticles ...
Iron (Fe), one of the most abundant elements on Earth, can appear in different structural phases associated with contrasting magnetic properties, depending on temperature and pressure. The most common phase is a-Fe, which has a body-centered cubic (bcc) structure and is ferromagnetic. Another iron allotrope, y-Fe, a high temperature phase in bulk, has a face-centered cubic structure (fcc). However, this iron allotrope has been stabilized at ...
Multitasking nanoparticles for intracellular imaging and biosensing Ghent University
The goal of this project is to develop novel functional nanoparticles as advanced tools for
intracellular imaging and biosensing. The design of these nanoparticles involves the use of
semiconductor nanocrystals, or quantum dots (QDs), as bright and stable luminescent markers
encapsulated in a protective silica matrix. These QD@SiO2 nanoparticles are further functionalized with plasmonic nanocrystals, such as gold or silver ...
Identification of factors affecting physicochemical fate of metallic nanoparticles released into surface waters Ghent University
The project identifies parameters affecting the fate of metallic nanoparticles released into surface waters and reveals kinetics of transformation processes occurring after such release. In addition, environmental factors affecting remobilization of adsorbed or precipitated metallic nanoparticles into surface waters are studied. Focus is also laid on developing analytical methods to quantify metallic nanoparticles in surface waters.

Improved intracellular delivery of upconversion nanoparticles by laser-induced vapor nanobubbles for multimodal bio-imaging applications Ghent University
Vapor nanobubble induced membrane poration will be explored as novel method for efficient delivery of upconversion nanoparticles into the cytosol of living cells. Benefits for in vivo cell tracking will be demonstrated over standard endocytic nanoparticle uptake, including improved labeling uniformity, high-throughput cell labeling, reduced toxicity, improved long term visibility and better signal quantification.
In situ synthesis and anchoring of gold and titania nanoparticles on metal organic frameworks Ghent University
In this project water stable MOFs will be synthesized. In a second step the MOFs will be applied as host matrixes for the anchoring of gold and titania nanoparticles which will be synthesized in situ in the MOF framework. The resulting NP@MOF materials will be evaluated as catatalysts in the epoxidation of different olefins and as a photocatalyst.
