Diversity of Potential (Bio)Technological Applications of Amino Acid-Based Ionic Liquids

Abstract

This review explores the emerging potential of amino acid-based ionic liquids (AA ILs) in various (bio)applications, emphasizing their unique properties and versatility. It provides a comprehensive analysis of recent advancements, covering applications in drug delivery, catalysis, environmental remediation, and biotechnology. The review also offers an overview of the synthetic methods for preparing AA ILs, highlighting both traditional and innovative approaches, and examines key physicochemical properties—such as biocompatibility, stability, and tunability—that make AA ILs highly attractive for diverse applications. Additionally, challenges hindering their widespread adoption, including high production costs, toxicity concerns, scalability issues, and environmental impact, are discussed. This review concludes with perspectives on future research directions and strategies to overcome these challenges, unlocking the full potential of AA ILs in both scientific and industrial contexts.
