Ancient administrative handwritten documents: X-ray analysis and imaging

Giorgio Margaritondo, Frédéric Kaplan, Fauzia Albertin

Handwritten characters in administrative antique documents from three centuries have been detected using different synchrotron X-ray imaging techniques. Heavy elements in ancient inks, present even for everyday administrative manuscripts as shown by X-ray ...

X-ray spectrometry and imaging for ancient administrative handwritten documents

Giorgio Margaritondo, Frédéric Kaplan, Fauzia Albertin, Marco Stampanoni

‘Venice Time Machine’ is an international program whose objective is transforming the ‘Archivio di Stato’ – 80 km of archival records documenting every aspect of 1000 years of Venetian history – into an open-access digital information bank. Our study is pa ...

Gold nanoparticles: BSA (Bovine Serum Albumin) coating and X-ray irradiation produce variable-spectrum photoluminescence

Giorgio Margaritondo

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 ...

Optimization of Gold Nanoparticle Photoluminescence by Alkanethiolation

Giorgio Margaritondo, Ying Chen

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 ...

Gold nanoparticles as multimodality imaging agents for brain gliomas

Giorgio Margaritondo

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 ...

X-ray-induced Cu deposition and patterning on insulators at room temperature

Giorgio Margaritondo, Ying Chen

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 ...
