Highly efficient, wavelength-tunable, gold nanoparticle based optothermal nanoconvertors
Article Abstract:
A photon-to-thermal energy conversion nanosystem based the near-infrared irradiation of one-dimensional gold nanoparticles (nanrods) is highly efficient and tunable to the incident wavelength. The specificity, with respect to the wavelength of the incident light, makes the highly efficient, particle based, optothermal nanoconvertors suitable for potential use in multicolor detection on biochips and related sensors and as ideal contrasting agents for optoacoustic biomedical imaging applications.

Ultrafast laser studies of the photothermal properties of gold nanocages
Article Abstract:
The energy transfer from the gold nanocages into the surrounding environment (water) as well as the coherently excited vibrational modes of the nanocages was studied by femtosecond pump-probe spectroscopy. The time scale for energy was found to increase the size of the particles, with the relaxation time being independent of the laser intensity.
