網頁2024年4月12日 · In this study, we describe the fast-responsive nanoemulsion (NE)-based silver ion (Ag+)-selective optode based on colorimetrically silver ion-responsive ionic liquid-based dye (ILD). The ILD comprises purely functional sensing molecules, a protonated cationic merocyanine dye (KD-M13-H+) and an anionic Ag+ ionophore (BDM-SO3−), and … 網頁What makes the channel cation selective? The amino acid sequences of the pore‐forming helices and the adjacent loop components contain three rings of negatively charged residues. One of them is located within the transmembrane region of the pore, and the other two flank the cytosolic entrance to the pore.
