**7. Conclusions**

In this book chapter an overview of the latest advances and research highlights in the field of MFs has been done, especially concerning the use of room-temperature ILs as fluid carriers. As it has been described, there are numerous MF applications that could benefit from IL features such as low flammability, negligible vapor pressure and tunability. However, although a lot of work has been done, there are still problems that have to be overcome if a wider commercialization of IL-based MFs is desired. Therefore, these new horizons broadened by their potential uses are, at the same time, encouraging and challenging.
