SURFACE MODIFICATION OF MAGNETITE-GOLD DUMBBELL NANOPARTICLES WITH FLUORESCENT DYES FOR NEW OPPORTUNITIES IN VISUALIZATION

摘要

Due to unique properties, magnetic nanomaterials are widely used in many branches of science and technology. One of the most perspective and actively developed areas are biomedical application: the target drug delivery, magnetic hyperthermia, biosensors and contrasting materials for magnetic resonance imaging (MRI). Hybrid materials based on nanoparticles with different surface nature as well as different chemical properties represent particularly especial interest. Such materials can be control modified in various ways simultaneously, in particular with drugs and targeted molecules. Surface modification of nanoparticles with fluorescence dyes opens horizons for visualization capabilities, also allows us to trace the behavior of particles in a biological environment, which is essential for their future biomedical applications [2].
