Outline of Final Research Achievements

One of the most rapidly developing and exciting applications of nanotechnology in biomedical research is the development of biocompatible nanoparticles (NPs) for use in multiple powerful and highly complementary imaging modalities.Gd-based inorganic nanoparticles such as Gd2O3 have recently been investigated as potential positive contrast agents in magnetic resonance imaging (MRI). However, our main goal is to synthesize and isolate new size-controlled and biocompatible paramagnetic metal oxide NPs, Gd2O3 and MnO, as a bimodal contrast agent for use in photoacoustic (PA) and MR imaging through the fusion of inorganic NPs and organic materials.
