Magnetofluorescent nanoparticles for bimodaldetection of breast cancer cells

摘要

Silica-encapsulated iron oxide composite nanoparticles were synthesized and characterized in terms of morphological and physico-chemical properties. These nanoparticles exhibited both fluorescent and magnetic properties useful for labeling of breast cancer cells. The mechanism of uptake by tumor cells, the pathway of degradation and the potential toxicity of these magnetofluorescent nanoparticles were investigated, suggesting that they could be developed as an efficient and safe bimodal contrast agent for detection of breast cancer cells.
