Nanotechnology, and specifically the use of nanoparticles (NPs), has been intensively explored during the recent decades in order to solve unmet clinical needs and face different biotechnological challenges. However, their success has been rather modest due to several limitations associated with the use of current nanomaterials. In this sense, one of the aspects in which current NPs have failed is in the development of complex formulations, including biological cues in/onto their surface in a cost-effective manner. Moreover, the potential toxicity of the chemicals used for NP synthesis is still an important safety and environmental concern that prevents the implementation of many of such formulations. In this scenario, naturally occurring NPs offer a unique opportunity to overcome these biocompatibility, efficacy and cost-effectiveness issues.
