Gold nanoparticles sensing with diffusion reflection measurement as a new medical diagnostics application

The ability to quantitatively and noninvasively detect nanoparticles in vivo has important implications on their development as optical sensors for medical diagnostics. We suggest a new method for cancer detection based on diffusion reflection (DR) measurements of gold nanorods (GNR). In our talk, the ability to extract optical properties of phantoms and their GNR concentrations from DR measurements will demonstrate. We will report, for the first time, GNR detection through upper tissue-like phantom layers, as well as the detection of a tumor presented as highly concentrated GNR placed deep within a phantom.
