silica coated gold nanorods as photoacoustic

  • Photoacoustic Imaging of Mesenchymal Stem Cells in Living

    Jun 10, 2012· Here, we report the use of silicacoated gold nanorods as a contrast agent for photoacoustic imaging and quantitation of mesenchymal stem cells in rodent muscle tissue. The silica coating increased the uptake of gold into the cell more than 5fold, yet no toxicity or proliferation changes were observed in cells loaded with this contrast agent.

    Jan 18, 2011· Abstract. Photoacoustic signal generation by metal nanoparticles relies on the efficient conversion of light to heat, its transfer to the environment, and the production of pressure transients. In this study we demonstrate that a dielectric shell has a strong influence on the amplitude of the generated photoacoustic signal and that silicacoated gold nanorods of the same optical density are capable of producing about 3fold higher photoacoustic signals than nanorods without silica coating.
