Functionalized Gold Nanoparticles

Biomolecule functionalized gold nanoparticles offer a broad range of applications in biomedical and bioanalytical areas. In this work, we investigated the spectroscopy behavior of gold nanoparticles modified with mercapto amino acid, cysteine. We found that the interaction of gold nanoparticles with cysteine resulted in a shift in the plasmon bands to higher wavelengths at the lower concentration of cysteine and in acidity solution.

Quantitative cellular in vitro nanoparticle uptake measurements are possible with a large number of different techniques, however, all have their respective restrictions. Here, we demonstrate the application of synchrotron-based X-ray fluorescence imaging (XFI) on prostate tumor cells, which have internalized differently functionalized gold nanoparticles. Total nanoparticle uptake on the order of a few hundred picograms could be conveniently observed with microsamples consisting of only a few hundreds of cells. A comparison with mass spectroscopy quantification is provided, experimental results are both supported and sensitivity limits of this XFI approach extrapolated by Monte-Carlo simulations, yielding a minimum detectable nanoparticle mass of just 5 pg. This study demonstrates the high sensitivity level of XFI, allowing non-destructive uptake measurements with very small microsamples within just seconds of irradiation time.
