Radiolabeling of Nanoshells with Cu-64 and In-111 for PET and SPECT Imaging in Rats

Xie H., Wang Z., Bao A., Goins B., Phillips W.T., Coleman C.L., Texas Southern University, US

Here we report for the first time the radioactive labeling of gold-silica nanoshells with Cu-64 and In-111. A bifunctional polyethylene glycol (PEG2000) is used as crosslinker to connect nanoshells with DOTA or DTPA, which are [...]

Gold nanoshells aided optical imaging in vitro, in vivo and ex vivo

Lee M., Loo C., Gobin A.M., West J., Halas N., Drezek R., Korea Electronics Technology Institute, KR

Scattering-based optical imaging technologies such as Optical Coherence Tomography (OCT) and Reflectance Confocal Microscopy (RCM) offer a unique non-invasive approach to the detection, diagnosis, and monitoring of cancer. In this article, we describe the use [...]

Vibrational Modes of Metal Nanoshells

Kirakosyan A.S., Shahbazyan T.V., Jackson State University, US

We study coherent oscillations of radial breathing modes in metal nanoparticles with a dielectric core. Vibrational modes are impulsively excited by a rapid heating of the particle lattice that occurs after laser excitation, while the [...]
