These days Ionic liquids (ILs) are getting more attention and catching more eyes based on numerous advantages they can offer, including low volatility, excellent thermal and chemical stability, easy handling, remarkable conductivity, and facile design. These astonishing materials are formed via asymmetric cations and anions. They can mainly be found in a liquid state where temperatures are below 100 °C. Therefore, due to their unique features, they can be considered a perfect and desirable candidate in several fields, including electrochemical biosensors and detecting agents; they can play their roles as electrolytes. These unique features prompted us to present a precise and short review of the different fabrication methods of Ionic liquids. Herein, after a laconic description of ILs, a diverse range of fabrication methods was investigated, and a succinct description was given in each approach. Furthermore, where needed, some clear illustrations were used to boost apprehend. Perspectives, remarks, and challenges of different fabrication methods have been given, respectively.
