Rapid electrochemical impedance spectroscopy for protein detection in Lab-on-a-Chip devices
T. Pardy(a); N. Sleptsuk(a); M. Min(a); J. Ojarand(a); T. Lakspere(a,b); K. Palm(b)

We present results in rapid solution impedance spectroscopy to detect protein interactions (antibody-antigen) in human serum. Two different serum-antibody mixtures are measured in cuvettes, interfaced with screen-printed electrodes to determine whether the experimental setup can detect differences in composition.

Finite element modelling for the optimization of temperature control in Lab-on-a-Chip devices
T. Pardy(a,b); T. Rang(a); I. Tulp(b)

The presented finite element model aims to help in the development of Lab-on-a-Chip devices which require temperature control. The model simulates the thermal system in such devices to enable in silico validation of designs and geometry optimization, and aims to be a versatile tool supporting multiple temperature control methods.

Advanced Microfluidic Mixing Device for the Study of Macromolecule Dynamics
Shubha Jain, F. Azam, Dr. H. N. Unni

We have developed and characterized a micro-fluidic mixer to study the macro-molecule dynamics such as kinetics of protein folding, DNA sequencing, single molecule study and detection etc. on a micro-second timescale. Numerical simulation has been performed to analyse the study of mixing performance of micro-fluidics channel.

A combined cell placement and migration assay device for cancer cell anti-migration drug screening
Colin L. Hisey1,2, Oihane Mitxelena-Iribarren2,3, Miguel Martinez-Calderon2, Sergio Arana2,3, Maite Mujika2,3, S.M. Olaizola2, Derek J. Hansford1

We have developed a microfluidic device capable of hydrodynamically trapping cells over polymer lines which encourage 1D migration based on topographical cues. These lines have been fabricated with both femtosecond laser ablation and dewetting/stamping. This type of precise control will allow precise microfluidic assessment of potential drug targets to limit cancer cell migration.

Microelectrode For Microdroplet Activity: A Survey on Design
Noor Faezah Ismail, Nasri Sulaiman and Nurul Amziah Md Yunus

Electrowetting basic operation is by having the microdroplet activity based on the electric field generated from the active microelectrodes that are designed and fabricated on the glass or pcb substrate. The design of the microelectrode can affect the result of the microdroplet movement, direction, size and etc. In this work, a few comparisons on the effectiveness from different electrode shapes have been made.

Development of a nucleic acid-based amplification test as point-of-care rapid test detecting sexually-transmitted diseases for home-care
Vicky Tröger, Anja Scherber, Dirk Kuhlmeier, Indrek Tulp, Marko Lehes, Steffen Howitz, Toni Bohatzsch, Tamas Pardy

The main problem of early diagnosis of STI is the lack of suitable systems. Therefore a quick home test is needed. In this poster, a microfluidic cartridge combining an isothermal amplification with detection on a lateral flow strip is presented.

Advanced Microfluidic Mixing Device for the Study of Macromolecule Dynamics
Shubha Jain, F. Azam, H.N.Unni

We have developed and characterized a micro-fluidic mixer to study the macro-molecule dynamics such as kinetics of protein folding, DNA sequencing, single molecule study and detection etc. on a micro-second timescale. It is observed that geometry of channel has significant impact on the mixing performance of channel and also mixing time. This mixer could be used for trapping, sequencing of micro and macro molecules such as cell, DNA and protein samples under flow condition

Innovative technology that enables RNAi in difficult to transfect cells
Christina Yamada, Kathryn Robinson, Allison St. Amand, Zaklina Strezoska, Greg Wardle, Anastasia Khvorova, Devin Leake

Investigations at Dharmacon have led to the development of innovative siRNA molecules that can be delivered into difficult-to-transfect cells without additional lipid reagents, virus, or instruments. This technology, Accell siRNA reagents, enables gene knockdown for functional genomic studies in a wide variety of cell types. In some instances, cells can be continuously dosed with Accell siRNAs to enable target gene knockdown for extended durations.
