“…It is reasonable to infer that the lateral-direction frictional force is also influenced by surface energy. Hydrogen decreases the DLC surface energy [27,30]; whereas the presence of silver on the top surface increases the surface energy [2,5,31]. Therefore the chemical composition partially explains the results that hydrogenated films had lower μ than hydrogen-free films, and that DLC nanocomposite films doped with silver had higher μ than pure DLC films.…”

In this study we have deposited silver-containing hydrogenated and hydrogen-free diamondlike carbon (DLC) nanocomposite thin films by plasma immersion ion implantation-deposition methods. The surface and nano-tribological characteristics were studied by x-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and nano-scratching experiments. The silver doping was found to have no measurable effect on sp 2 -sp 3 hybridization of the hydrogenated DLC matrix and only a slight effect on the hydrogen-free DLC matrix. The surface topography was analyzed by surface imaging. High-and low-order roughness determined by AFM characterization was correlated to the DLC growth mechanism and revealed the smoothing effect of silver. The nano-tribological characteristics were explained in terms of friction mechanisms and mechanical properties in correlation to the surface characteristics. It was discovered that the adhesion friction was the dominant friction mechanism; the adhesion force between the scratching tip and DLC surface was decreased by hydrogenation and increased by silver doping.

“…The formation of Ag nanostructures in the pores of SiO2 template on the Si substrate was carried out by electroless galvanic displacement method using an aqueous solution of Ag nitrate (AgNO3) and hydrofluoric acid (HF), which dissociates in water into individual cations and anions (Ag + , NO3 -, H + , F -) as was published in our previous publication 43 . The resulted ions participate in three parallel processes 44,45 : Scanning electron microscopy (SEM, Carl Zeiss ULTRA 55, FE-SEM) was chosen to characterize the surface morphology of the obtained samples. To clarify the crystal structure of silver dendrites, the X-Ray diffraction (XRD) patterns were measured using X'Pert Pro X-ray diffractometer from PANalytical B.V. in the Bragg-Brentano arrangement.…”

Surface-enhanced Raman spectroscopy (SERS) is a promising optical method for analyzing molecular samples of various nature. Most SERS studies are of an applied nature indicating a serious potential for their application in analytical practice. Dendrite-like nanostructures have great potential for SERS, but the lack of a method for their predictable production significantly limits their implementation. In this paper, a method for controllable obtaining spatially

“…Our approach is based on a synergic combination of high resolution electron beam lithography (EBL) and electroless deposition of silver. 19,[31][32][33][34][35][36] In all means, this approach is a combination of top down and bottom up approach at nanometer regime. EBL offers the typical advantages of top-down approaches such as high resolution, no limitations on 2D layout, and stringent control of size and position of the planar nanostructures, whereas electroless deposition, when combined with small 2D structures, enables a fine shaping with spherical symmetry of metal nanostructures.…”

Emerging fabrication techniques for 3D nano-structuring in plasmonics and single molecule studies

The application of new methods and techniques to fields such as biology and medicine is becoming more and more demanding since the request of detailed information down to single molecules is a scientific necessity and a technical realistic possibility. In this effort a key role is played by emerging fabrication techniques. One of the hardest challenges is to incorporate the third dimension in the design and fabrication of novel devices. Significantly, this means that conventional nano-fabrication methods, intrinsically useful for planar structuring, have to be substituted or complemented with new approaches. In this paper we show how emerging techniques can be used for 3D structuring of noble metals down to nanoscale. In particular, the paper deals with electroless deposition of silver, ion and electron beam induced deposition, focused ion beam milling, and two-photon lithography. We exploited these techniques to fabricate different plasmonics nanolenses, nanoprobes and novel beads for optical tweezers. In the future these devices will be used for the manipulation and chemical investigation of single cells with sensitivity down to a few molecules in label free conditions and native environment. Although this paper is only devoted to nanofabrication, we foresee that the fields of biology and medicine will directly gain substantial advantages from this approach.
