Structural and plasmonic properties of gold nanocrystals
The design of gold nanoparticles for surface-enhanced Raman scattering (SERS) and plasmonic enhanced fluorescence are more involved than simply maximizing the local field enhancement. The enhancement is a function of the excitation wavelength relative to the plasmon resonance as well as the …

Polymer- and Bioadditives-Assisted Synthesis and Surface Modification of Anisotropic Gold Nanocrystals
… and scalable syntheses of small anisotropic nanocrystals in high yield utilizing a polymer and small thiolated compounds as shape-directing agents during growth, which enhance the long-term shape stability and colloidal stability after functionalization. Chapter 1 is a literature review of …

High Deviatoric Strain Engineering/
… we demonstrate that controlled sintering of the nanocrystals in self-assembled superlattices of alkanethiol-passivated gold nanoparticles can happen at room temperature through deviatoric stress-induced displacement of the organic ligands. We find that combining a hydrostatic pressure of order …

Functional stability of plant peroxiredoxins
… On the other hand, a stable interaction of gold-nanocrystals with introduced thiol-groups of the variants was investigated as another necessity to visualise conformational changes via DXT. The specificity of binding events could be considerably increased by supplementing the binding reaction …

Photothermal properties and applications of gold nanorods
Gold nanorods (GNRs) with their special optical and photothermal properties have attracted attention recently for their potential applications in fields such as photothermal therapy, drug delivery, biomedical imaging and chemical sensing. These anisotropic gold nanocrystals have tunable surface …

Quantitative Theories of Nanocrystal Growth Processes
Nanocrystals are an important field of study in the 21st century. Crystallites that are nanometers in size have very different properties from their bulk analogs because quantum mechanical effects become dominant at such small length scales. When a crystallite becomes small enough, the quantum …
