Fabrication of tissue phantoms with embedded CdSe/ZnS quantum dots, gold and upconversion nanoparticles

摘要

Phantoms are imitations of biological tissue, which are used for modeling of the light propagation in biological tissues. They are required for different purposes, and also repeatability of results are achieved with them. So the fabrication of solid tissue phantoms which contains nanoparticles with high absorbance or fluorescence is actual problem for scientists. This work describes development, fabrication, and characterization of such solid tissue phantoms.. CdSe/ZnS quantum dots, gold and upconversion nanoparticles were synthesized and used for embedding to the phantoms. Luminescence of samples with CdSe/ZnS quantum dots and upconversion nanoparticles were recorded. A sample of gold nanorods was analyzed using thermal gravimetric analysis. It can be concluded that the samples are well suited for experiments on laser thermolysis.
