In this Highlight, Hasma Jaganathan and Albena Ivanisevic from Purdue University present a unique nanostructure design using DNA that can serve as potential magnetic resonance imaging (MRI) agents. By attaching gold and iron oxide nanoparticles on linear strands of DNA, nanoparticle chains are easily formed by self-assembly and through DNA-based enzymes. Furthermore, gold–iron oxide nanoparticle chains exhibit fast proton relaxation times that improve MRI signals and do not induce in vitro toxicity.

Metal/oxide nanosystems with different spatial organizations have attracted a remarkable interest for their unique features and multi-functional properties, which can be finely tuned by controlling the interplay between their structure, morphology and composition. In this Highlight, Davide Barreca and co-workers at Padova University describe how the interfacial interactions between metal nanoparticles and oxides significantly impact the system properties and play a key role for future advancements in their science and technology.
