A high-throughput microfluidic rare cell enrichment system based on dielectrophoresis and filtering
Ozkayar, Gurhan; Yalcin, Yagmur Demircan; Ozgur, Ebru; Gündüz, Ufuk; Külah, Haluk (2016-05-27)
In this study, a MEMS-based microfluidic device combining DEP-based cell manipulation with size-based filtration for the enrichment of CTCs from blood with high-throughput was developed. Positive-DEP (pDEP) force and the hydrodynamic force have been used to fine-tune the cell movement over the planar electrodes (sliding) at a high flow rate (30 mu l/min). While smaller sized RBCs passed through the gaps and were directed to the waste channels, cancer cells (K562 cells) were filtered and directed to the canc...
A novel analytical system involving hydride generation and gold-coated W-coil trapping atomic absorption spectrometry for selenium determination at ng l(-1) level
Kula, I.; Arslan, Y.; Bakirdere, S.; Ataman, Osman Yavuz (2008-08-01)
A novel analytical technique was developed where gaseous hydrogen selenide formed by sodium tetra hydrobora te reduction is transported to and trapped on a resistively heated gold-coated W-coil atom trap for in situ preconcentration. Gold coating on W-coil was prepared by using an organic solution of Au. The atom trap is held at 165 degrees C during the collection stage and is heated up to 675 degrees C for revolatilization; analyte species formed are transported to an externally heated quartz T-tube where ...
A direct injection method for blood cells into microchannels from pure blood droplets with switchable in-situ distillation of erythrocytes
Ciftlik, Ata Tuna; Külah, Haluk (2008-06-25)
This paper represents a direct injection method for leukocytes into microfluidic channels using negative dielectrophoresis. The blood sample is a heparinated pure blood droplet and injection is realized on-chip without any external microfluidic connections to the microchip. During injection erythrocytes are immobilized in-situ at injection reservoir electrodes. The method is easily applicable to most BioMEMS applications requiring direct injection of cells from pure blood and to eliminate pressure driven co...
A fully integrated autonomous power management system with high power capacity and novel MPPT for thermoelectric energy harvesters in IoT/wearable applications
Tabrizi, Hamed Osouli; Jayaweera, H. M. P. C.; Muhtaroglu, Ali (2017-11-17)
This paper reports a fully integrated autonomous power management system for thermoelectric energy harvesting with application in batteryless IoT/Wearable devices. The novel maximum power point tracking (MPPT) algorithm does not require open circuit voltage measurement. The proposed system delivers 0.5 mA current with 1 V regulated output based on simulations, which is the highest output current for a fully integrated converter reported in the literature for ultra-low voltage applications, to the best knowl...
A new processable electrochromic polymer based on an electron deficient fluorene derivative with a high coloration efficiency
Carbas, Buket Bezgin; Kivrak, Arif; Önal, Ahmet Muhtar (2011-12-30)
A new fluorenone based soluble polymer, namely poly(2,7-bis-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yI)-fluoren-9-one) (PPFP), containing propylenedioxythiophene (ProDOT) as a donor and fluorenone (FO) as an acceptor group is highlighted. Electrochemical polymerization of 2,7bis-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yI)-fluoren-9-one (PFP) was achieved in dichloromethane/acetonitrile mixture with 0.1 M tetrabutylammonium hexafluorophosphate via potential cycling. The poly...
