AB  - Fluorescent nanostructures were prepared by functionalization of gold nanoparticles with riboflavin molecules and used as probes for synchrotron radiation deep ultraviolet (SR-DUV) fluorescence imaging of gluteraldehyde-fixed Candida albicans cells. The nanoparticles were characterized by transmission electron microscopy (TEM) and optical spectroscopy techniques. The TEM analysis showed that the nanostructures were 6 nm in diameter, while the results of the fluorescence spectroscopies confirmed the photoluminescence of the nanoparticles. The SR-DUV imaging showed that it was possible to distinguish the fluorescence of the nanoparticles from the autofluorescence of the cells, as well as that the local maxima of the signal pertaining to the fluorescence of goldriboflavin nanostructures were mostly positioned on the surfaces of the C. albicans cells of spherical morphology.

AB  - Biocompatible fluorescent nanostructures were prepared by a functionalization of gold nanoparticles with the amino acid tryptophan. The gold-tryptophan bioconjugates were investigated by TEM and HRTEM and various spectroscopy methods (XPS, FTIR, UV-vis and photoluminescence). It was found that the gold nanoparticles, initially 8 nm in diameter, aggregate in the presence of the amino acid. From the XPS and FTIR spectroscopy results, it was concluded that the tryptophan gold interactions mainly take place via indole and carboxyl groups. Although the indole group is involved in the interaction with the gold surfaces, the tryptophan-gold hybrids showed strong fluorescence due to the presence of multilayers of tryptophan. Deep ultra violet (DUV) imaging performed at the SOLEIL synchrotron showed that It is possible to detect these hybrid nanostructures within Escherichia coli cells.
