Novel Single Walled Carbon Nanotube Based Magnetic-Fluorescent Nanohybrids as Dual-Modal MRI/Optical Imaging Probes


Article Preview

Gadolinium chelate and Quantum Dots (QDs) decorated single walled carbon nanotubes (SWNTs) nanohybrids (SWNT-Gd-QDs) were designed for dual-modal cellular imaging via magnetic resonance imaging (MRI) and optical imaging. The nanohybrids were prepared via a simple and novel layer-by-layer (LBL) assembly in combination with covalent connection strategy. The SWNT-Gd-QDs nanohybrids showed a strong near-infrared photoluminescence (PL) emission at room temperature and enhanced T1-weighted and T2-weighted MRI signals in water. Thus, the nanohybrids combine magnetic and fluorescent properties and can serve as dual-modal MRI/optical imaging contrast agent.
