In diagnostics analysis, creatinine is a biomarker for the evaluation of renal and muscular dystrophy in various biology and closely related to the life activities of the organism. In this research, we investigated the transmission surface plasmon resonance-imaging (TSPR-i) with a 3-channel microfluidic cell. TSPR-i based on the exploitation of propagating SPR is the technique for monitoring the changes...
Because digital games are interactive media, it is expected that digital games have various effects on players. In this paper, the previous studies on digital game effects are reviewed based on Cultivation Theory. Cultivation Theory is often used in television studies and to use it in digital game studies, the need for content analysis and improvement of measurement is addressed as problems. Content...
A waveguide-based SPR sensor for double analyte detections was prepared with a single waveguide, and sensing for ammonia and water vapors were carried out. A BK-7 slide glass was used as a waveguide core, and two pairs of Ag films (50 nm) / sensing polymer films with different thicknesses were prepared separately on the waveguide. White light was input from the substrate edge, and the output light...
In this work, we report the fabrication of grating structure of solid-state electrolyte layers on dye-TiO2 film by nanoimprint technique using PDMS stamp, and their application to photo-electric conversion devices. PDMS grating pattern is imprinted from BD-R or nickel templates. Silver electrode was deposited on the patterned solid-state electrolyte layers. Surface plasmon resonance excitation is...
Gold nanoparticles (AuNPs) have a unique property called localized surface plasmon resonance (LSPR). LSPR excitation wavelength is strongly dependent on size of gold nanoparticles. At the LSPR wavelength, gold nanoparticles exhibit an enormous electric field enhancement extended from their surface. We have been synthesized gold nanoparticles using chemical reduction of hydrogen tetrachloroaurate (HAuCl4)...
A hybrid sensor of quartz crystal microbalance (QCM) and optical waveguide (OWG) spectroscopies was prepared, and in-situ observations were carried out for lead phthalocyanine (PbPc) film depositions using vacuum evaporation technique. The peak wavelength of the absorption spectra changed with the PbPc film thickness. The responses of QCM frequency and optical absorption were also observed, and they...
In this work, electropolymerization of carboxylated conducting polymer/CNTs composites have been studied for construction of surface plasmon resonance immunosensor. The electrochemical experiment was performed in 1.0 M tetrabutylammonium hexafluorophosphate (TBAPF6) in acetonitrile containing 10 mM monomers, thianaphthene-2-carboxylic acid and benzothiophene-2-propanoic acid, and CNTs in acetonitrile...
Digital Games have become part of everyday life all over the world. In this article, we suggest to use Quality of Life (QOL) to investigate the characteristics of game play and to evaluate games. We measured emotional changes caused by game play using a QOL questionnaire specialized in the detection of the mental change (POMS-Brief Form) in Interrupted Time-Series Design. As a result, the analysis...
