In the work, silicalite particles were used for the surface modification of pH-sensitive field-effect transistors (pH-FETs) with the purpose of developing new creatinine-sensitive biosensor. Creatinine deiminase (CD) adsorbed on the surface of silicalite-coated pH-FET served as a bioselective membrane. The biosensor based on CD immobilized in glutaraldehycie vapor (GA) was taken as control. The creatinine-sensitive biosensor obtained by adsorption on silicalite was shown to have better analytical characteristics (two-to threefold increased sensitivity to creatinine, three-to fourfold lesser response and recovery times, a decrease of the detection limit of creatinine determination to 5 mu m, etc.).

Photoconductivity of P3HT films measured by time-resolved THz spectroscopy Esentürk, Okan; Heilweil, Edwin J. (Optical Society of America (OSA); 2007-01-01) Photoconductivities of P3HT polymer films varying in molecular weight were directly measured and compared using optical pump-THz probe spectroscopy. Conductivities of P3HT polymers depend on the polymer length, ring orientation regularity and film morphology. © 2007 Optical Society of America.
Reliability improvement of RF MEMS devices based on lifetime measurements Gürbüz, Ozan Doğan; Demir, Şimşek; Akın, Tayfun; Department of Electrical and Electronics Engineering (2010) This thesis presents fabrication of shunt, capacitive contact type RF MEMS switches which are designed according to given mm-wave performance specifications. The designed switches are modified for investigation in terms of reliability and lifetime. To observe the real-time performance of switches a time domain measurement setup is established and a CV (capacitance vs. voltage) curve measurement system is also included to measure CV curves, pull-in and hold-down voltages and the shifts of these due to actuat...
Development of electrochemical etch-stop techniques for integrated MEMS sensors Yaşınok, Gözde Ceren; Akın, Tayfun; Department of Electrical and Electronics Engineering (2006) This thesis presents the development of electrochemical etch-stop techniques (ECES) to achieve high precision 3-dimensional integrated MEMS sensors with wet anisotropic etching by applying proper voltages to various regions in silicon. The anisotropic etchant is selected as tetra methyl ammonium hydroxide, TMAH, considering its high silicon etch rate, selectivity towards SiO2, and CMOS compatibility, especially during front-side etching of the chip/wafer. A number of parameters affecting the etching are inv...
Vacuum-processed polyethylene as a dielectric for low operating voltage organic field effect transistors Kanbur, Yasin; Irimia-Vladu, Mihai; Glowacki, Eric D.; Voss, Gundula; Baumgartner, Melanie; Schwabegger, Guenther; Leonat, Lucia; Ullah, Mujeeb; Sarica, Hizir; ERTEN ELA, ŞULE; Schwoediauer, Reinhard; Sitter, Helmut; Kucukyavuz, Zuhal; Bauer, Siegfried; Sariciftci, Niyazi Serdar (2012-05-01) We report on the fabrication and performance of vacuum-processed organic field effect transistors utilizing evaporated low-density polyethylene (LD-PE) as a dielectric layer. With C-60 as the organic semiconductor, we demonstrate low operating voltage transistors with field effect mobilities in excess of 4 cm(2)/Vs. Devices with pentacene showed a mobility of 0.16 cm(2)/Vs. Devices using tyrian Purple as semiconductor show low-voltage ambipolar operation with equal electron and hole mobilities of similar to...
Design and implementation of microwave lumped components and system integration using MEMS technology Temoçin, Engin Ufuk; Akın, Tayfun; Department of Electrical and Electronics Engineering (2006) This thesis presents the design and fabrication of coplanar waveguide to microstrip transitions and planar spiral inductors, and the design of metal-insulator-metal capacitors, a planar band-pass, and a low-pass filter structures as an application for the inductors and capacitors using the RF MEMS technology. This thesis also includes a packaging method for RF MEMS devices with the use of “benzocyclobutene” as bonding material. The transition structures are formed by four different methods between coplanar ...
