Research ArticleOpen accessIn the keywordsOptical Properties and Sugar Content Determination of Commercial Carbonated Drinks using Surface Plasmon ResonanceW. Y.W. Yusmawati, H. P. Chuah, M. Y.W. MahmoodIn this study, an optical sensor based on Kretschmann SPR technique was used to detect the sugar content in commercial carbonated drinks. Three samples of carbonated drinks labeled as "Coke", "100 Plus" and "F&N Orange" have been chosen for angle scan SPR measurements. All the measurements were carried out at room temperature using He-Ne laser beam (632.8nm, 5mW) as a … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2007 · 8,784 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptical Properties of Crosslinked Chitosan Thin Film with Glutaraldehyde Using Surface Plasmon Resonance TechniqueYap Wing Fen, W. Mahmood Mat Yunus, Mohd Maarof Moksin et al.Problem statement: The aim of this research is to study the optical properties of crosslinked chitosan thin film with glutaraldehyde using Surface Plasmon Resonance (SPR) technique. Approach: The crosslinked chitosan is synthesized by homogeneous reaction of medium molecular weight chitosan in aqueous acetic acid solution with glutaraldehyde as crosslinking agent. Four different amount of chitosan, i.e., 0.40, 0.50, 0.60 and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 9,624 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordUse of Optical Reflectometry to Observe Various Concentrations of GlucoseHariyadi SoetedjoProblem statement: Monitoring technique on glucose is a hot topic as this compound has been considered to be important in human healthties. Optical reflectometry has been used to study various concentrations of glucose dissolved in the water. Approach: The self-construction of reflectometer used was of hemi-cylinder aluminum to allow light beam strikes the sample at 70° for sor p-polarization state. … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,144 accessesView PDF Cite
