• acidic molecules and can be involved in the formation of surface salts. For example, potassium carboxylates generated on the surface of mica assist the process of adsorption of fatty acids [44][45][46][47] and their derivatives [48]. The character of the interactions between the oligomers and the

• used bare or primed, prior to the coating with LPSQ-COOH/X, with a monolayer of N-acetylcysteine, citric acid or thioglycolic acid. The primers are bound to mica by ionic bonds (carboxylates) and simultaneously provide the substrate with new organic functions capable of hydrogen bonding [49]. Atomic

• hydrogen bonding. Supramolecular assemblies of LPSQ-COOH/X on primed mica The adsorption of LPSQ-COOH/X on native mica is governed by the formation of surface salts–potassium carboxylates. It was of interest to alter these ionic interactions between LPSQ and mica and block the K+ ions by adsorption of

Mater. 2010, 22, 2804–2813], we carried out a wide set of reactions using Mn(II) carboxylates and Mn2(CO)10 as precursors with varying amounts of

• several reactions where a manganese precursor was thermally decomposed in octadecene containing varying amounts of sulfur and free surfactant (L). As manganese precursors we used manganese(II) carboxylates (Mn(OH)Ol, MnOl2, and MnSt2; abbreviations of chemical names can be found in the Experimental

• -lysine core (N-EEKKKKKES-C vs N-AKKKKKAS-C) interact with carboxylates on the SAM-biosensor chip surface in a different way. The presence of the glutamic acid residues stabilizes the mode of interaction with the charged surface. When lysine residues are flanked by neutral amino acids, the interaction
