Abstract
Quantum dots (QDs) are new class of fluorescent inorganic nanocrystals which have been used for in vitro and in vivo imaging. Their unique optical properties such as broad excitation spectra, narrow emission spectrum and resistance to photobleaching make them ideal for biological labeling. Sentinel lymph node biopsy is a means of ultra-staging cancer metastasis and is now the standard of care in breast cancer surgery. Localisation of sentinel nodes is also important in the treatment of head and neck cancer. Current tracers for SLN biopsy include the blue dye have various limitations that could be overcome by quantum dots that emit in near infrared range (>700 nm). To safely deliver QDs they must be encapsulated in a biocompatible coating. In this study we encapsulate CdTe QDs with new nanocomposite material based on a silsesquioxane modified poly (carbonate-urea) urethane polymer, and evaluated their spectroscopic properties.
