A cartridge based sensor array platform for multiple coagulation measurements from plasma
Cakmak, O.; Ermek, E.; Kilinc, N.; Bulut, S.; Baris, I.; Kavakli, I. H.; Yaralıoğlu, Göksen Göksenin; Urey, H. (Royal Society of Chemistry, 2015)This paper proposes a MEMS-based sensor array enabling multiple clot-time tests for plasma in one disposable microfluidic cartridge. The versatile LoC (Lab-on-Chip) platform technology is demonstrated here for real-time ... -
LoC sensor array platform for real-time coagulation measurements
Cakmak, O.; Kılınç, N.; Ermek, E.; Mostafazadeh, A.; Elbuken, Ç.; Yaralıoğlu, Göksen Göksenin; Urey, H. (IEEE, 2014)This paper reports a MEMS-based sensor array enabling multiple clot-time tests in one disposable microfluidic cartridge using plasma.

Microcantilever based LoC system for coagulation measurements
Çakmak, O.; Ermek, E.; Kılınç, N.; Barış, I.; Kavaklı, I. H.; Yaralıoğlu, Göksen Göksenin; Urey, H. (Chemical and Biological Microsystems Society, 2014)In this paper, a microcantilever-based system enabling multiple coagulation tests on the same disposable cartridge is demonstrated. The system consists of independent cartridge and reader unit. The actuation of the nickel ... -
Precision density and viscosity measurement using two cantilevers with different widths
Cakmak, O.; Ermek, E.; Kilinc, N.; Yaralıoğlu, Göksen Göksenin; Urey, H. (Elsevier, 2015)We introduce a novel method for fast measurement of liquid viscosity and density using two cantilevers with different geometries. Our method can be used for real-time monitoring in lab on chip systems and offer high accuracy ... -
Two cantilever based sytem for viscosity and density monitoring
Cakmak, O.; Ermek, E.; Kilinc, N.; Yaralıoğlu, Göksen Göksenin; Urey, H. (IEEE, 2015)Viscosity and density measurements in liquids in real-time is challenging. Previous MEMS based approaches use frequency sweeps for the purpose and those methods are slow and not real-time. We show that high precision ...
