In this work, a novel nanomaterial deposition technique involving the triboelectrification (TE) of glass fibers (GF) to create attractive charges on their surface was investigated. Through TE, continuous GF were positively charged thus, attracting negatively graphene oxide (GO) nanoparticles dispersed in solution. The electrical increased with intensity TE process. deposited GO coating then che...

Manipulation of DNA fibers is very useful technique for gene analysis such as Fluorescent In Situ Hybridization (FISH). In conventional methods for manipulation of DNA fibers, FISH efficiency often decreases due to the tight adhesion between DNA fibers and substrates. In this paper, we propose a micro glass-phonorecord with concentric grooves for suspending DNA fibers with centrifugal force. As...

We describe an approach for producing robust multimaterial chalcogenide glass fibers for mid-wave and long-wave mid-infrared transmission. By combining the traditional rod-in-tube process with multimaterial coextrusion, we prepare a hybrid glass-polymer preform that is drawn continuously into a robust step-index fiber with a built-in, thermally compatible polymer jacket. Using tellurium-based c...

We report the optical studies of nanohole arrays in metallic coatings on cleaved optical fibers and also on glass substrates. Nanoholes are produced using electron-beam lithography and range in size from 100 to 700 nm; the pitch is varied from 300 to 3000 nm. Transmission properties are examined using visible 632.8 nm and infrared 1550 nm laser light. The observed interference patterns are dete...

In this study, we analyzed the effects of synthetic vitreous fibers (SVFs) on a mesothelial (MeT5A) and a fibroblast cell line (NIH3T3), compared to those exerted by crocidolite asbestos fibers. SVFs (glass wool, rock wools) do not induce significant changes in cell mortality, whereas crocidolite asbestos fibers caused a dose-dependent cytotoxicity. We investigated the correlation between the f...

In recent years, the fabrication of multifunctional fibers has expanded for multiple applications that require the transmission of both light and electricity. Fibers featuring these two properties are usually composed either of a single material that supports the different characteristics or of a combination of different materials. In this work, we fabricated (i) novel single-core step-index op...
