“…The most striking feature is the change of sign from the case of a binary SDS-Fe 3 O 4 (samples S8) to that of the ternary composite system (S7) with the lowest amount of PPY. While it is known that pure magnetite particles have positive values of ζ [39], this potential becomes more negative in a continuous manner as the relative amount of the conducting polymer is increased in the SDS-Fe 3 O 4 -PPY aggregates.…”

“…Surface modification and functionalization are widely practiced on nanoparticles used for biomedical applications. Different types of modifiers have been used to modify nanoparticle surfaces for biomedical purposes, such as carboxylatefunctional compounds (Sahoo et al, 2005), phosphate-functional compounds (Portet et al, 2001;Mutin et al, 2003), silica (Johnson et al, 1996;Alcala and Real, 2006), gold (Lin et al, 2001), dextran (Lee et al, 2002), polyethylene glycol (Kim et al, 2001;Paul et al, 2004), polyvinyl alcohol (Nishio et al, 2004), alginate (Kroll et al, 1996), and chitosan .…”

Contrast agents, such as iron oxide, enhance MR images by altering the relaxation times of tissues in which the agent is present. They can also be used to label targeted molecular imaging probes. Unfortunately, no molecular imaging probe is currently available on the clinical MRI market. A promising platform for MRI contrast agent development is nanotechnology, where superparamagnetic iron oxide nanoparticles (SPIONS) are tailored for MR contrast enhancement, and/or for molecular imaging. SPIONs can be produced using a range of methods and the choice of method will be influenced by the characteristics most important for a particular application. In addition, the ability to attach molecular markers to SPIONS heralds their application in molecular imaging.There are many reviews on SPION synthesis for MRI; however, these tend to be targeted to a chemistry audience. The development of MRI contrast agents attracts experienced researchers from many fields including some researchers with little knowledge of medical imaging or MRI. This situation presents medical radiation practitioners with opportunities for involvement, collaboration or leadership in research depending on their level of commitment and their ability to learn. Medical radiation practitioners already possess a large portion of the understanding, knowledge and skills necessary for involvement in MRI development and molecular imaging. Their expertise in imaging technology, patient care and radiation safety provides them with skills that are directly applicable to research on the development and application of SPIONs and MRI.In this paper we argue that MRI SPIONs, currently limited to major research centres, will have widespread clinical use in the future. We believe that knowledge about this growing area of research provides an opportunity for medical radiation practitioners to enhance their specialised expertise to ensure best practice in a truly multi-disciplinary environment. This review outlines how and why SPIONs can be synthesised and examines their characteristics and limitations in the context of MR imaging.
