Abstract:
Biomimetic ion channels can be made to display the high sensitivity of natural protein nanopores and to develop new properties as a function of the material used. How to design the best future biomimetic channels? The main challenges are to control their sensitivity, as well as their syntheses, chemical modifications, insertion and lifetime in a lipid membrane. To address these challenges, we have recently designed short cyclodextrin nanotubes characterized by mass spectrometry and high-resolution transmission electron microscopy. They form non-permanent ion channels in lipid bilayers. Here we show how to improve the nanotube insertion in order to limit multiple insertions, how to stabilize biomimetic channels into the membrane, and how to understand the ion dynamics in confined medium scale.

Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
