Multi-photon microscopy enhanced: Exploring annular beams and gold nano-particles for improved imaging
… the excitation laser, and using functionalized gold-nanoparticles (AuNPs) as contrast media. In addition, an experimental MPM system is presented. This system was set up to conduct proof-of-principle experiments. Theoretical calculations, performed as part of the project, show that annular laser …

Gold(I) complexes and co oxidation catalysts
Isonitrile gold(I) nitrates, (RNC)AuNO₃ (R = Buᵗ, Et or Xy) have been prepared and fully characterised. These join the rare set of gold(I) species exhibiting ligation to oxygen and are the first examples of gold(I) bonded to both carbon and oxygen. Molecular aggregations of the monomeric units were …

Apertureless Scanning Nearfield Optical Microscopy with Ultra-high Temporal Resolution
… light allows to study ultrafast processes on the nano scale. As a proof of principle system we choose the mechanical oscillations exhibited by gold nano discs that are impulsively heated through a short pump pulse. First we provide the theoretical foundation needed to understand the optical and …
