Journal ArticleDOI
Cancer Cell Imaging and Photothermal Therapy in the Near-Infrared Region by Using Gold Nanorods
TL;DR: It is found that, after exposure to continuous red laser at 800 nm, malignant cells require about half the laser energy to be photothermally destroyed than the nonmalignant cells, so both efficient cancer cell diagnostics and selective photothermal therapy are realized at the same time.
Journal ArticleDOI
Calculated Absorption and Scattering Properties of Gold Nanoparticles of Different Size, Shape, and Composition: Applications in Biological Imaging and Biomedicine
TL;DR: While nanorods with a higher aspect ratio along with a smaller effective radius are the best photoabsorbing nanoparticles, the highest scattering contrast for imaging applications is obtained from nanorod of high aspect ratio with a larger effective radius.
Journal ArticleDOI
Noble Metals on the Nanoscale: Optical and Photothermal Properties and Some Applications in Imaging, Sensing, Biology, and Medicine
TL;DR: How the unique tunability of the plasmon resonance properties of metal nanoparticles through variation of their size, shape, composition, and medium allows chemists to design nanostructures geared for specific bio-applications is emphasized.
Journal ArticleDOI
Plasmonic photothermal therapy (PPTT) using gold nanoparticles
TL;DR: The development of the PPTT method is discussed with special emphasis on the recent in vitro and in vivo success using gold nanospheres coupled with visible lasers and gold nanorods and silica–gold nanoshells coupled with near-infrared lasers.
Journal ArticleDOI
Surface plasmon resonance scattering and absorption of anti-EGFR antibody conjugated gold nanoparticles in cancer diagnostics: applications in oral cancer.
TL;DR: The results suggest that SPR scattering imaging or SPR absorption spectroscopy generated from antibody conjugated gold nanoparticles can be useful in molecular biosensor techniques for the diagnosis and investigation of oral epithelial living cancer cells in vivo and in vitro.
