Te combination of the size-dependent properties of nano- of some nanoparticles can be used to create new imaging materials with the noninvasive characterisation in molec- techniques, for example, the superparamagnetism of iron ular imaging is a powerful combination that is being suc- oxide nanoparticles for magnetic particle imaging. cessfully applied across disciplines. In the past ten years, In this issue, we have aimed to provide a platform we have witnessed the development of, literally, hundreds for high-quality contributions on nanoparticles application of nanoparticle-based probes for molecular imaging. All to molecular imaging. Original papers and review articles major imaging techniques have been enhanced by the use focusing on the latest application of nanoparticle-based of nanoparticles, particularly magnetic resonance imaging imaging probes were submitted. Te topics treated include (MRI), positron emission tomography (PET), and optical the application of iron oxides for MRI, for PET/MRI, and for imaging. Te use of iron oxide nanoparticles for T -weighted drug delivery; new synthesis approaches to obtain magnetic and/or T -weighted MRI, the design of radioisotope chelator- nanoparticles-based contrast agents; polymeric nanoparticles free particles for PET, and new developments in fuorescent1 for ultrasound imaging; new computed tomography (CT) nanoparticles2 (carbon dots and upconverting nanoparticles) contrast agents; and quantum dots for multiplex optical are important milestones in the feld. Tere are two key imaging. We received a total of 16 submissions, and afer features in nanoparticle-based probes which are seldom two rounds of rigorous review, 9 papers were accepted for found in traditional imaging probes: multimodality and publications in this special issue. multifunctionality.
