The Stability

As one of the main methods to study biomembranes, the construction of highly active bionic biomembrane systems is very important. Based on the hybrid film of gold nanoparticles and cellulose, a novel system of bionic biomembrane is demonstrated. The ratio effects of lecithin to cholesterin on the stability of bilayer lipid membranes are studied. Lipid solutions that can form stable membranes in the air and in some aqueous solutions are prepared. The bionic biomembranes composed of bilayer lipid membranes and hybrid films of gold nanoparticles and cellulose can be sustained for a long period in aqueous solutions. The bionic biomembranes also exhibit some interesting electrochemical properties.

The Stability

This study aims to provide arguments for an increase in the stability of bilayer lipid membranes (BLM) in an electrical field in presence of $ \mathrm{CuO} $ nanoparticles. Moreover, the sustainability of BLM becomes more stable with increasing of nanoparticles concentration. It is shown that an increase in the stability of BLM in an electrical field is mainly due to an increase in the coefficient of linear tension of the edge of a pore, which is forming in BLM. It is shown as well, that the presence of nanoparticles of $ \mathrm{CuO} $ in the solution surrounding BLM leads to a decrease in the conductivity of the BLM.

New Research

This review identifies the ways in which tethered bilayer lipid membranes (tBLMs) can be used for the identification of the actions of antimicrobials against lipid bilayers. Much of the new research in this area has originated, or included researchers from, the southern hemisphere, Australia and New Zealand in particular. More and more, tBLMs are replacing liposome release assays, black lipid membranes and patch-clamp electrophysiological techniques because they use fewer reagents, are able to obtain results far more quickly and can provide a uniformity of responses with fewer artefacts. In this work, we describe how tBLM technology can and has been used to identify the actions of numerous antimicrobial agents.
