Detection of Clinical Biomarkers using a novel parabolic microchip diagnostic platform

Hill D., Hearty S., Basabe-Desmonts L., Blue R., McAtamney C., O’Kennedy R., MacCraith B., Dublin City University, IE

A polymer paraboloid microchip is utilised for performing fluorescence detection in point-of-care devices, employing a mass producible and effective strategy. The chip consists of a single piece of moulded plastic containing nine parabolic elements, with [...]

One-step White Blood Cell Separation from Whole Blood

Park J.M., Kim B.C., Lee J-G, Samsung Advanced Institute of Technology (SAIT), KR

Isolation of White Blood Cells (also called “WBC”) from whole blood is a first very important step for many in vitro assays. One currently accepted technique for WBC separation, referred to as the conventional manual [...]

GRAVI-Chip: Automation of Microfluics Affinity Assay based on Magnetic Nanoparticle

Rossier J.S., Baranek S., Morier P., Vulliet F., Vollet C., Reymond F., DiagnoSwiss SA, CH

An automated nanoparticle based microfluidic platform called GRAVI™ will be presented here as a novel benchtop robotised system for fast and automated ELISA analysis in low volumes. This system can handle samples and reagents from [...]

MEMS based examination platform for a neuro-muscular communication in a co-culture system coupled to a multi-electrode-array

Fischer M., Klett M., Fernekorn U., Augspurger C., Schober A., Technische Universitat Ilmenau, DE

Development of a sensor-connected in vitro neuromuscular co-culture system may provide a useful tool for interpreting mutual signal transfers between the cell species and for future applications in drug screening. A glass-based, autoclavable, micro fluidic [...]

Feasibility Study of Cochlear-like Acoustic Sensor using PMN-PT Single Crystal Cantilever Array

Hur S., Lee S.Q., Kim W.D., Korea Institute of Machnery & Materials, KR

The mammalian cochlea is an organ that performs the conversion of the incoming mechanical energy into electrical signals in the auditory nerve fibers. Current cochlear Implants have been developed in an effort to restore sensorineural [...]

Multiband THz detection and imaging devices

Popa-Simil I.L., Popa-Simil L., Popa-Simil I.L., Popa-Simil L., LAVM Llc., US

Terahertz imaging finds more and more applications in homeland security, medical, and life sciences applications. While THz sources and detection systems are gaining ground, the ability of electronics conversion systems to keep up with the [...]

Nano-gap high quality factor thin film SOI MEM resonators

Grogg D., Tekin C.H., Badila-Ciressan D.N., Tsamados D., Mazza M., Ionescu M.A., Ecole Polytechnique Fédérale de Lausanne, CH

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 [...]

10GHz Surface Acoustic Wave Filter Fabrication by UV Nano-Imprint

Chen H.J.H., Chen N.H., Chen H.J.H., Chen N.H., Lin C.H., Huang F.S., National Tsing Hua University, TW

Surface acoustic wave (SAW) devices have been widely implemented for wireless communications. Recently, SAW devices continue the upward trend in frequency for higher functionality. Nanoimpirnt can adequately offer mass production technique on interdigital transducer (IDT) [...]

Deposition of functional PZT films as actuators in MEMS devices by high rate sputtering

Quenzer H.-J., Dudde R., Jacobsen H., Wagner B., Föll H., Fraunhofer ISIT, DE

Crack and void free polycrystalline Lead Zirconate Titanate (PZT) films in the range of 5 µm to 10 µm have been successfully deposited on silicon substrates using a novel high rate gas flow sputtering process. [...]
