Microfluidic device for analysis of protein biomarkers using magnetic bead surface coverage detection

Martinus Gijs, Hüseyin Cumhur Tekin, Cynthia Scherz

We present a microfluidic device for on-chip analysis of low-concentration protein biomarkers. A new detection method, based on the magnetic capture of proteins via superparamagnetic beads and counting the surface coverage of the latter is presented. The p ...

Chaotic mixing using source-sink microfluidic flows in a PDMS chip

Martinus Gijs, Abdeljalil Sayah, Caroline Vandevyver, Hüseyin Cumhur Tekin, Ata Tuna Ciftlik, Venkataragavalu Sivagnanam

We present an active fixed-volume mixer based on the creation of multiple source–sink microfluidic flows in a polydimethylsiloxane (PDMS) chip without the need of external or internal pumps. To do so, four different pressure-controlled actuation chambers a ...

Active microfluidic mixer using virtual source-sink pairs for DNA purification

Martinus Gijs, Caroline Vandevyver, Hüseyin Cumhur Tekin

We present an active mixer based on the creation of virtual source-sink pairs in a polydimethylsiloxane (PDMS) chip. Perfect mixing is achieved in only a sub-second time interval for a compact 5 μL mixing volume. This excellent performance is achieved than ...

A fixed-volume microfluidic mixer realized using multilayer PDMS technology

Martinus Gijs, Hüseyin Cumhur Tekin

We present leakage-free valves and an efficient fixed-volume mixer fabricated using a four-layer soft lithography technique in polydimethylsiloxane (PDMS). Mixing is achieved with a 95% efficiency in a few seconds by creating circular flow patterns inside ...

Double gate movable body Micro-Electro-Mechanical FET as hysteretic switch: Application to data transmission systems

Mihai Adrian Ionescu, Maher Kayal, Cédric Meinen, Dimitrios Tsamados, Daniel Grogg, Hüseyin Cumhur Tekin

This paper reports on the fabrication, experimental characterization and data transmission application of a double-gate movable body FET. As its name suggests, the proposed movable-body Micro-Electro-Mechanical FET (MB-MEMFET) is a hybrid MEMS-semiconducto ...

Laterally vibrating-body double gate MOSFET with improved signal detection

Mihai Adrian Ionescu, Marco Mazza, Dimitrios Tsamados, Daniel Grogg, Nicoleta-Diana Ciressan, Hüseyin Cumhur Tekin

Laterally vibrating-body double-gate MOSFET that shows a +30 dB signal increase compared to an identical resonator operating with pure capacitive detection is reported. The double-gate MOSFET is fabricated on SOI substrate with silicon film thickness of 1. ...

Nano-gap high quality factor thin film SOI MEM resonators

Mihai Adrian Ionescu, Marco Mazza, Dimitrios Tsamados, Daniel Grogg, Nicoleta-Diana Ciressan, Hüseyin Cumhur Tekin

A 1.25 m thin SOI micro-electro-mechanical (MEM) resonator with a quality factor of 100’000 at 24.6 MHz is demonstrated. A nanogap fabrication process allows the fabrication of < 200 nm gaps, allowing for low polarization voltages. A motional resistance of ...
