Highly Stable and Reproducible Au Nanorod Arrays for Near-Infrared Optofluidic SERS sensor
Samir Kumar, Takao Fukuoka, Kyoko Namura +1
Surface-enhanced Raman spectroscopy (SERS) is a sensitive vibrational spectroscopy technique that can enable fast and non-destructive detection of trace molecules. SERS substrates…
Multilayer Thin-Film Flake Dispersion Gel for Surface-Enhanced Raman Spectroscopy
Samir Kumar, Misa Kanagawa, Kyoko Namura +2
Ag nanorod arrays/dielectrics/mirror-structured multilayer thin-film are well known, highly sensitive surface-enhanced Raman scattering (SERS) substrates that enhance the Raman sca…
Highly reproducible, large scale inkjet-printed Ag nanoparticles-ink SERS substrate
Samir Kumar, Kyoko Namura, Daisuke Kumaki +2
We report the fabrication of a low cost, and highly reproducible large scale surface-enhanced Raman spectroscopy substrate using an inkjet-printed Ag nanoparticle ink (AgNI). The A…
Water Droplet Bouncing on a non-Superhydrophobic Si Nanosprings
Samir Kumar, Kyoko Namura, Motofumi Suzuki +1
Self-cleaning surfaces often make use of superhydrophobic coatings that repel water. Here, we report a hydrophobic Si nanospring surface, that effectively suppresses wetting by rep…
Plasmonic Nanoslit Arrays Fabricated by Serial Bideposition: Optical and Surface-Enhanced Raman Scattering Study
Samir Kumar, Yusuke Doi, Kyoko Namura +1
Recently, studies have been carried out on attempts to combine surface-enhanced Surface-enhanced Raman spectroscopy (SERS) substrates that can be based on either localized surface…
Manifestation of Resonance-Related Chaos in Coupled Josephson Junctions
Yu. M. Shukrinov, M. Hamdipour, M. R. Kolahchi +2
Chaotic features of systems of coupled Josephson junctions are studied. Manifestation of chaos in the temporal dependence of the electric charge, related to a parametric resonance,…
