Recent updates on applications of ionic liquids (ILs) for biomedical sciences

Ionic liquids (ILs) are known as green solvents that comprise of cations and anions in equal ratios and exist as liquid at temperature below 100 degrees C. They possess desirable properties such as biocompatibility, solubility, and inherent tunability that makes them suitable for biomedical applications. In recent years, the implementation of ILs in biomedical sciences has been increased dramatically as they have exceptional characteristics and tunability. Herein, we have highlighted the ILs and their characteristics. Further, we have briefly discussed the applications in biomedical sciences such as pharmaceutical delivery carriers, proteins or nucleic acid stabilizers, biosensors, and antimicrobial agents. Challenges and future perspectives of ILs have also been highlighted.
