3D porous structure of ionic liquid-delaminated Ti₃C₂ MXene nanosheets for enhanced electrochemical sensing of tryptophan in real samples.

ABSTRACT: Accurate measurement of tryptophan (Trp) levels is crucial for clinical and research purposes, such as nutritional assessment, disorder diagnosis, condition management, and the study of the role of Trp in disease pathophysiology. Herein, the intercalation of 1-octyl-3-methylimidazolium chloride [OMIM]⁺Cl^- ionic liquids (ILs) between the layers of Ti₃C₂ MXenes results in a 3D porous structure with a large active surface area and high interlayer spacing (d-spacing). Confined [OMIM]⁺ ions enhance the electroactive sites and Trp transfer pathways at the Ti₃C₂ MXene and IL interfaces and improve the electron transfer efficiency for Trp oxidation, improving Ti₃C₂ MXene stability via strong π‒π and
