The black lipid membranes (BLMs) are artificial membrane systems that have been widely used in the study of different biological processes. In this paper the planar bilayer lipid membranes have been used to study the behavior of thiolipid molecules-dipalmitoyl-phosphatidyl-ethanolamine-mercaptopropionamide (DPPE-MPA) and cholesteryl 3-mercaptopropionate (Chs-MPA)-as compared to classical BLM made of natural lipids. We present our experiments on black thiolipid bilayer (BTM) formation from a thiolipid solution and basic results of pump currents generated by sodium-potassium pump-Na(+),K(+)-ATP-ase-introduced to such bilayer systems via proteoliposome adsorption with subsequent fusion. Our results imply that no substantial difference exists between BLMs formed from classical lipids and those made from thiolipids used in this study. The same thiolipid molecules were subsequently used for the formation of covalently bound, tethered bilayer lipid membranes (t-BLMs) on polycrystalline gold electrodes. Similarly, as in the case of BLMs, we took advantage of proteoliposome adsorption/fusion to obtain a t-BLM system with reconstituted enzyme. The vesicle fusion on hydrophobic or hydrophilic substrates is one of the main ways to obtain a bilayer system with incorporated biological species. In this paper we present also our preliminary results of electrochemical experiments using rapid solution exchange technique on such t-BLMs systems and their comparison with painted solid supported membranes (SSMs) and BLMs. We have also followed the process of vesicles fusion onto thiolipid monolayer by means of in situ atomic force microscopy in tapping mode (TM-AFM). On the basis of these experiments, we conclude that DPPE-MPA and Chs-MPA molecules used in our experiments preserve lipid properties, allowing for at least partial reconstitution of Na(+),K(+)-ATP-ase into such t-BLMs. On the other hand, the relatively compact organization on polycrystalline gold and the hydrophobic nature of the first monolayer of tethered thiolipids slows down the proteoliposome fusion onto such monolayers and consequently hinders the protein insertion. However, this effect can be overcome by mechanical stimulus that facilitates proteoliposome delamination onto the self-assembled monolayer.
