A simplemethod for the fabrication of stable and highly active surface enhanced Raman scattering (SERS) substrate by exploiting the optical properties of the silver nanoparticles (AgNPs) and organizational characteristics of the polymer is presented. Homogeneous distribution ofAgNPs is achieved with the usage of poly (4,7-di-2,3-dihydrothieno [3,4-b] [1,4] dioxin-5-yl-2,1,3 benzoselena diazole) (PESeE) film coated on the indium tin oxide glass (ITO) surface. The obtained structure ensured the emergence of a large number of hot spots where the localization of electromagnetic energy can result in enhancement of the Raman signal. The effect of the PESeE film thickness, the density of AgNPs added to the polymer film, and the concentration of silver ion solution on the morphology of the substrate and the enhancement of the SERS signal was revealed by using field emission scanning electron microscopy (FE-SEM) and SERS measurements. Enhancement power, homogeneity, and stability of the PESeE-AgNPs substrate were also investigated with measurement of the Raman probe. Spot-to-spot and batch-to-batch reproducibilities of the prepared substrate were calculated as 8.4%, and 10.2% (RSD %) respectively. Due to these properties, PESeE-AgNPs SERS substrate can be a good candidate for the detection and sensor application of various biological and chemical analytes.

Efficient Ceria-Supported Rhodium Nanoparticles as an Electrocatalyst for Hydrogen Evolution Akbayrak, Merve; Önal, Ahmet Muhtar (The Electrochemical Society, 2019-12-13) Rh-0/CeO2 catalystwas prepared by the reduction of Rh+3 ions on CeO2 surface and characterized by transmission electron microscopy, inductively coupled plasma optical emission spectrometry, X-ray photoelectron spectroscopy and powder X-ray diffractometry techniques. To investigate its electrocatalytic activity for H-2 evolution reaction, a glassy carbon electrode (GCE) was modified with Rh-0/CeO2. The modified electrode was found to exhibit a high electrocatalytic activity (turnover frequency (TOF): 1.56 s(...
A sol-gel derived AgCl photochromic coating on glass for SERS chemical sensor application Volkan, Mürvet; Vo-Dinh, T (Elsevier BV, 2005-05-13) A new optically translucent material has been prepared that acts as a substrate for surface-enhanced Raman spectroscopy. This material is a silica matrix, synthesized by the sol-gel method and containing in situ precipitated AgCl particles which serve as precursors for nanoparticles of elemental silver. Reduction of AgCl to silver nanoparticles is achieved by UV irradiation. The SERS-active medium was distributed on glass supports (cover glass slips, 0.5 turn thick), hence producing thin, sturdy, and optica...
Paper Based Glucose Biosensor Using Graphene Modified with a Conducting Polymer and Gold Nanoparticles GOKOGLAN, Tugba Ceren; KESİK, Melis; SOYLEMEZ, Saniye; YÜKSEL, Recep; Ünalan, Hüsnü Emrah; Toppare, Levent Kamil (The Electrochemical Society, 2017-01-01) In this work a novel approach was reported for glucose detection using disposable paper based electrodes consisting graphene modified with a conducting polymer, glucose oxidase (GOx) and gold nanoparticles. For the first time, a conducting polymer; poly(9,9-di-(2-ethylhexyl)-fluorenyl-2,7-diyl)-end capped with 2,5-diphenyl-1,2,4-oxadiazole (PFLO) was spread over graphene coated papers and used as a matrix for glucose detection. To finalize the desired biosensor, the enzyme GOx was immobilized with gold nano...
Electrodeposition of Ni/TiC Nanocomposites in the Presence of a Cationic Dispersant Acet, Nurcan; Eroglu, Damla (The Electrochemical Society, 2018-01-01) The effect of a cationic dispersant, polyethyleneimine (PEI) on electrodeposition of nickel/titanium carbide (Ni/TiC) nanocomposites is characterized. Enhancing the dispersion of TiC nanoparticles in the electrolyte and increasing TiC amount and uniformity in the deposit are crucial to get superior mechanical and tribological nanocomposite properties. Therefore, a key challenge in reaching enhanced composites is the optimization of the dispersant concentration that improves the nanoparticle dispersion in th...
Metamaterial Absorber Based Multifunctional Sensors Sabah, Cumali (The Electrochemical Society, 2016-01-01) In this paper, several important applications of a metamaterial absorber (MA) based sensors such as temperature, pressure, moisture, and density are presented. Since the sensing ability mostly considers the resonance frequency, the frequency range where the resonance shifts occur linearly or non-linearly depending on the temperature, pressure, moisture, and density changes is selected carefully. The model is composed of X shaped resonators (XSR), dielectric substrate, the sensing layer, dielectric substrate...
