NIR-labeled perfluoropolyether nanoemulsions for drug delivery and imaging.

ABSTRACT: Theranostic nanoparticle development recently took center stage in the field of drug delivery nanoreagent design. Theranostic nanoparticles combine therapeutic delivery systems (liposomes, micelles, nanoemulsions, etc.) with imaging reagents (MRI, optical, PET, CT). This combination allows for non-invasive in vivo monitoring of therapeutic nanoparticles in diseased organs and tissues. Here, we report a novel perfluoropolyether (PFPE) nanoemulsion with a water-insoluble lipophilic drug. The formulation enables non-invasive monitoring of nanoemulsion biodistribution using two imaging modalities, (19)F MRI and near-infrared (NIR) optical imaging. The nanoemulsion is composed of PFPE-tyramide as a (19)F MRI tracer, hydrocarbon oil, surfactants, and a NIR dye. Preparation utilizes a combination
