We show that by using different x-ray irradiation times of BSA-coated Au nanoparticles (NPs) we can change their ultraviolet-stimulated photoluminescence and shift the spectral weight over the visible spectral range. This is due to the interplay of two emi ...

X-ray irradiation is shown to trigger the deposition of Cu from solution, at room temperature, on a wide variety of insulating substrates: glass, passivated Si, TiN/Ti/SiO2/Si and photoresists like PMMA and SU-8. The process is suitable for patterning and ...

We demonstrate that the combination of x-ray irradiation and capping by polyethylene glycol (PEG) produces excellent flexibility in controlling the structure of Au-Pd nanoparticles while preserving their catalytic performance. We specifically adopted two d ...
Surface thiolation was recently found to affect two important properties of gold nanoparticles: their size and the presence of visible luminescence under UV stimulation. We explored these phenomena by systematically analysing alkanethiolate coatings with d ...
The catalytic properties of Pd trigger a strong interest on the related catalysis by Au-Pd nanoparticles. However, the analysis of such phenomena was complicated so far by the presence of capping. Using x-ray irradiation, we could produce uncapped Au-Pd na ...
Background: Nanoparticles can be used for targeted drug delivery, in particular for brain cancer therapy. However, this requires a detailed analysis of nanoparticles from the associated microvasculature to the tumor, not easy because of the required high s ...
