Interactions of paramagnetic metal complexes with their biological environment can modulate magnetic resonance imaging (MRI) contrast–enhancing properties in different ways, and this has been widely exploited to create responsive probes that provide biochemical information. We survey progress two rapidly growing areas: the MRI detection biologically important ions, such as calcium, zinc, copper...
Background: Magnetic resonance imaging (MRI) contrast agents have an important role to differentiate healthy and diseased tissues. Access and design new contrast agents for the optimal use of MRI are necessary. This study aims to evaluate iron oxide–4A nanocomposite ability to act as a magnetic resonance imaging contrast agent.Materials and Methods: Iron oxide–4A nanocomposite (F4A) was syn...
Objective(s): The aim of this work was to prepare and characterize magnetic nanoparticles (MNPs) as theranostic system to act simultaneously as drug carrier and MRI contrast agent. Chitosan-coated MNPs (CMNPs) were prepared and loaded with silymarin. Silymarin-loaded CMNPs were characterized with various techniques and their potential as MRI contrast agent was also evaluated. Materials and Meth...
Amphiphilic triblock copolymers containing Fe(III) -catecholate complexes formulated as spherical- or cylindrical-shaped micellar nanoparticles (SMN and CMN, respectively) are described as new T1-weighted agents with high relaxivity, low cytotoxicity, and long-term stability in biological fluids. Relaxivities of both SMN and CMN exceed those of established gadolinium chelates across a wide rang...
Liver specific contrast media (LSCM) can be subdivided according to different modalities of hepatic distribution: exclusive distribution to the hepatocellular compartment can be obtained using CM which accumulate within the hepatocytes after slow infusion; other CM demonstrate combined perfusion and hepatocyte-selective properties, with an initial distribution to the vascular-interstitial compa...
