Introduction. This mini-review examines the mechanisms of damage to bacterial biofilms (BB) by particles metals (Au, Ag, Fe, Cu, Zn, Mg) and their oxides (AuО, SiO, Fe2О3, Ag2O, CuO, TiO2, ZnO, MgO). Emphasis is placed on mechanism which includes formation reactive oxygen species that affect redox state cell and, as a result, its death. The antibacterial action particles, well effect porosity d...

Metal oxide-based resistive random access memory devices are highly attractive candidates for next-generation nonvolatile memories, but the switching phenomena remain poorly understood. This article focuses on microscopic understanding of initial forming step, which is decisive process. The integrated effect in Ti/ HfO2/ TiWN metal insulator structures studied. After forming, transmission elect...

New issues come from the advent nanometric devices: defect and fault tolerance -at the physical, circuit and most importantly at the system levelis an enabling technology for building reliable nanoelectronic systems. Semiconductor manufacturers are responding to these challenges by introducing a variety of technical innovations, including new manufacture testing methodologies, virtual testing, ...

A strategy for an innovative, continuous and reversible LSPR tuning using DNA origami actuation to modulate the nanometric separation of two gold nanoparticles has been developed. The actuation mechanism is based on DNA hybridization, in particular three different DNA sequences were shown to induce resonance shift of up to 6 nm.

Original and effective syntheses of crystalline silver wires and saw bundles, using reduced Keggin polyoxomolybdovanadate (POM) as mediator and reducing agent, were performed in acetonitrile at room temperature; several parameters influencing the final silver 1D-structures, with micrometric length and nanometric thickness, were varied: the nature of the POM, silver salts, vanadium(iv) source an...

A peptide was designed to generate a sub-nanometric template that guides the growth of fluorescent gold nanoclusters. The peptide was endorsed with nucleating moieties and a three-dimensional structure that arrests the growth of ultrasmall nanoparticles. The nanoclusters are not cytotoxic and can be found in the cytosol of cells.
