Nanotechnology and global health
Nanotechnology offers a wide range of possible solutions to global health threats, from diagnostic devices, to innovative strategies for drug delivery, to vaccine design. These innovations have the potential to overcome basic biological challenges related to the immune response to pathogens in the case of vaccines, for example, or low on-target drug bioavailability. At the same time, they could also provide solutions to issues of a more practical nature, such as poor health infrastructures and lack of trained personnel in remote areas, or low adherence to therapeutic treatment regimen. However, despite the promises, nanotechnology-based solutions have so far struggled to have a direct and sustained impact on global health. Our Focus issue this month aims to describe the most recent nano-enabled solutions against infectious diseases, and discusses the existing challenges and possibilities associated with their implementation.
