Abstract

We report a single-step, microwave-assisted approach for the preparation of multifunctional magnetic nanocomposites. We demonstrate the link between synthetic methodology and the functionality of the nanocomposites as biomedical imaging agents.

Highlights

  • The choice of synthetic approach employed for the preparation of nanoparticles is of crucial importance when designing materials for a speci c function

  • Of growing recent interest has been the development of routes to nanoparticles which afford great control over particle shape and composition, vital in our efforts to realise an intimate understanding of their unique properties

  • Microwave approaches to particle synthesis have led to dramatic decreases in reaction times and greater control over product formation.[23,24,25,26,27,28,29]

Summary

Introduction

With these concerns in mind, we have employed microwaveassisted methods for the preparation of functionalised iron oxide nanoparticles, which are becoming increasingly attractive. The polyelectrolytes act as stabilisers preventing the further growth of the nanoparticles, while at the same time promoting colloidal stability of the particles in water
