Title of the speech: Thin films and nanostructures of diamond like carbon with metallic nanoparticles for sensor applications

Abstract: Diamond-like carbon (DLC) films is the subject of considerable attention due to their extraordinary properties such as low friction coefficient and high wear resistance; high corrosion resistance and chemical inertness; high electrical resistivity; infrared-transparency and high refractive index. Many applications of DLC films have already been implemented for practical use such as mechanical elements, optical components or biomaterials. Metal nanoparticle containing DLC films showing excellent potential in various practical applications attract much attention as well. The nanocomposite films containing the nanometer range sized noble metal nanoparticles of silver, gold or other metals like copper, embedded in a matrix such as amorphous carbon have been studied intensively, since such type of films exhibit antibacterial properties, they demonstrate surface plasmon resonance (SPR) and are promising materials for developing the elemental base of laser physics, opto- and micro-electronics devices.
In this work we present a short review on technology of deposition, structure and optical properties of DLC and DLC based silver nanocomposites grown by reactive magnetron sputtering, nanostructuring techniques and novel applications of this material including leaky wave optical sensors for the real time monitoring of bioprocesses. Plasmonic properties as well antibacterial properties of thin films composed of silver nanoparticles embedded in a diamond like carbon matrix are discussed versus concentration, size of nanoparticles.
