Protein behavior at the water–ionic liquid interface has been studied recently to better understand biological processes, biopharmaceutical stability, and bioanalytical measurements, and it can provide the foundations for new label-free and sensitive biomolecular detection tools. In their Communication on page 2559 ff., Damien W. M. Arrigan et al. studied lysozyme for the first time at the interface between water and the hydrophobic room-temperature ionic liquid [FAP]. A preconcentration strategy based on constant-potential adsorption followed by voltammetric desorption enables the detection of this protein.
