The analysis of standards measurements for a large clinical trial employing fluorescence spectroscopy shows that a well designed set of standards and frequent measurement should be an essential component of any optical device clinical trial.

An analytical model was used to develop an inverse model to estimate tissue optical properties from in vivo fluorescence measurements. The inverse model estimated optical parameters from the epithelial and stromal layers from fluorescence spectra.

Optical imaging techniques have shown promise for pre-cancer detection; furthermore, there is significant interest in identifying cancer specific biomarkers. We present optically interrogated contrast agents based on metal nanocrystals for optical im
