glucose oxidase modified electrodes

AZAK, Hacer | KURBANOĞLU, Sevinç | YILDIZ, Hüseyin Bekir | ÖZKAN, Sibel Ayşıl

The synthesis of derivatives of dithionepyrrole is a hot subject that has been studied extensively. In this study, a novel approach for constructing different glucose biosensors using conducting polymers of 4-(4H-dithyinol[3,2-b:2′,3′-d]pyroll-4-yl)aniline and 4-(4H-dithyinol[3,2-b:2′,3′-d]pyroll-4-yl)-[1,1′-biphenyl]-4-amine is proposed. After the synthesis and characterizations of the dithionepyrrole type monomers, they were used in glucose biosensing applications. The surface of gold electrode was modified with mercaptoethane sulfonic acid and p-aminothiophenol functionalized gold nanoparti ...Daha fazlası

Health status detection of neonates using infrared thermography and deep convolutional neural networks

ÖRNEK, Ahmet Haydar | CEYLAN, Murat | ERVURAL, Saim

Protection of body temperature is critically important for health. Diseases and infections cause local temperature imbalances in the body. Infrared Thermography (IRT), which is a non-invasive and non-contact method, has been used in medical applications for decades. Pre-diagnosis and follow-up treatment systems can be realized by monitoring the temperature distribution in the body. In this study, IRT and deep Convolutional Neural Networks (CNNs) models were used together for the first time to detect the health status of neonates. Neonatal thermal images have been taken in the Neonatal Intensiv ...Daha fazlası

Predictors Generation by Partial Least Square Regression for microwave characterization of dielectric materials

SADOU, Hakim | HACIB, Tarik | LE BIHAN, Yan | MEYER, Olivier | AÇIKGÖZ, Hulusi

In this paper, the microwave characterization of dielectric materials using open-ended coaxial line probe is proposed. The measuring cell is a coaxial waveguide terminated by a dielectric sample. The study consists in extracting the real and imaginary part of the relative dielectric permittivity (ε = ε′-jε’’) of the material under test from the measurements of the probe admittance (Ymes(f) = Gmes(f)+jBmes(f)) on a broad band frequency (f between 1 MHz and 1.8 GHz), hence a direct and inverse problems have to be solved. In order to build a database, the direct problem is solved using Finite Ele ...Daha fazlası
