Plasmonic nanoparticles in aqueous solution have long been known to fragment under irradiation with intense ultrafast laser pulses, creating progeny particles with diameters of a few nanometers. However, the mechanism of this process is still intensely deb ...

Light matter interaction can be boosted by several orders of magnitude by tailoring the photonic environment, thus enabling a wide range of applications. One particular example are plasmonic nanostructures that support localized surface plasmon polariton ( ...

Cells are powerful carriers that can help to improve the delivery of nanomedicines. One approach to use cells as carriers is to immobilize the nanoparticulate cargo on the cell surface. While a plethora of chemical conjugation strategies are available to b ...

Immense field enhancement and nanoscale confinement of light are possible within nanoparticle-on-mirror (NPoM) plasmonic resonators, which enable novel optically activated physical and chemical phenomena and render these nanocavities greatly sensitive to m ...

A new approach to optical diffraction tomography (ODT) based on intensity measurements is presented. By applying the Wolf transform directly to intensity measurements, we observed unexpected behavior in the 3D reconstruction of the sample. Such a reconstru ...

The current COVID-19 pandemic has showed the threats that viruses can cause to the whole world. Over 200 million infections and over 4.5 million deaths and enormous socio-economic impact were the output of the emergence of a single new pathogen: SARS-CoV-2 ...

The main focus of this thesis is the exploration of inorganic and metal-organic heterogeneous catalysts for hydrogen (H2) energy applications. In particular, we investigated metal nanoparticles (NPs) and metal-organic frameworks (MOFs) for their employment ...

Cancer is a major health burden worldwide and the leading cause of death in industrialized countries. Early detection is a primary factor of survival and remission rate. Classical imaging methods such as magnetic resonance imaging, ultrasound imaging and m ...

Surface-enhanced Raman spectroscopy (SERS) coupled with density functional theory (DFT) computations can characterise the adsorption orientation of a molecule on a nanoparticle surface. When using DFT to simulate SERS on a silver surface, one typically emp ...

Conventional therapeutics are often limited by their targeting ability, resulting in harmful and potential fatal side-effects for the patients. Recently, new strategies have been developed to improve target specificity of drugs in order to generate more ef ...

Efficient medical care fundamentally relies on the ability to provide a timely and accurate diagnosis. Thanks to advances in biomedical research, specific molecules called diagnostic molecular biomarkers have been discovered in the human body that help ind ...

Biocompatibility restrictions have limited the use of magnetic nanoparticles for magnetic hyperthermia therapy to iron oxides, namely magnetite (Fe3O4) and maghemite (gamma-Fe2O3). However, there is yet another magnetic iron oxide phase that has not been c ...

Firstly, this thesis presents the in vivo evaluation of a previously developed model system that utilizes CD4+ TE/M cells decorated with up to 100 polystyrene based nanoparticles per cell by maleimide thiol conjugation. These nanoparticle T-cell conjugates ...
