Over the past decades, nanotechnologies gained researchers’ attention because of the unique features that make nanostructures suitable for applications in several fields. Among these, nanomedicine represents a promising area of research also due to the possibility to develop multifunctional nanoplatforms for bioimaging, drug delivery, and hyperthermia treatment, just to list a few. However, some issues are related to the conventional methods of synthesis that can require conditions like very high temperatures or the use of toxic and pollutant reagents. For this reason, in the last years, studies focused on the development of simple and eco-friendly approaches able to overcome the mentioned problems.
