Microfluidic Platform for Point-of-Care Blood Typing
B. Scheufele, R. Gronmaier, J. Claussen, S. Haeberle, J. Kohnle, J. Ducree, R. Zengerle, H. Northoff and F.K. Gehring

We have developed a microfluidic platform for mass sensitive analysis of whole blood that allows fast and reliable Point-of-Care blood typing of the AB0 system requiring small sample volumes. Potential application areas of the microfluidic platform include emergency medical aid, clinics and doctor's surgeries.

Development of a Lab-on-a-Chip for the Characterization of Human Cells
Richter, L., Stepper, C., Mak, A., Brückl, H. and Ertl, P.

Cell chips are developed to continuously monitor mammalian cell population dynamics in a non-invasive manner. In the presented work we describe the design, fabrication and characterization of a lab-on-a-chip for quantitative cell analysis.

Label-free Identification of Microorganisms using a Contact-less Dielectric Microsensor
Ertl, P., Richter, L., Reinthaler, A., Stepper, C., Mak, A., Kast, M., Heer, R. and Brückl, H.

Microfabricated biochips are developed to continuously monitor cell population dynamics in a non-invasive manner. In the presented work we describe the novel combination of contact-less dielectric microsensors and microfluidics to promote biofilm formation for quantitative cell analysis.

Design, Manufacturing and Test of Disposable Microfluidic System for Blood-Plasma Separation
M. Kersaudy-Kerhoas, F. Amalou, D. Kavanagh, S. Marson, U. M. Attia, P. Summersgill, T. Ryan and M.P.Y. Desmulliez

Prenatal diagnosis to determine the outcome of pregnancies and detect conditions that may affect future pregnancies has risen as a big issue in the broad public. Analysis of fetal genetic material extracted from maternal blood is a smart alternative to invasive prenatal testing.

EasyBeacons™ - new Probes Ideal for Realtime PCR Detection of Methylation Status of Single CpG Duplets and SNPs
K. Skadhauge, C. Nielsen & U.B. Christensen

The EasyBeacons™ presented here are based on the novel technology Intercalating Nucleic Acid, INA®, linked to a fluorophore and a quencher. INA® is composed of normal DNA nucleotides and Intercalating Pseudo Nucleotides (IPNs). The fact that the EasyBeacons™ are mostly composed of normal DNA nucleotides means that in many respects EasyBeacons™ behave like DNA based probes, allowing use of standard buffers, primers and enzymes and hence reduces the optimisation efforts.

Novel Fluidics Microbead Trap/Flow Cell Enhances Speed/Sensitivity of Bead-Based Bioassays Up to 5-Fold
RM Ozanich, CJ Bruckner-Lea, JW Grate, MG Warner, BP Dockendorff, KC Antolick, HC Edberg, LH Johnson, AN Easterday

Pacific Northwest National Laboratory (PNNL) has developed a micro/nano particle trap that allows surface-functionalized magnetic or non-magnetic particles to be trapped with subsequent perfusion of sample, reagents and wash solutions, yielding significant (up to 5-fold) improvements in assay speed and sensitivity, while significantly reducing sample matrix effects.

Utilizing High Speed Photography to Optimize Low Volume Dispensing Conditions
Mary Cornett, Mitch Gordon and Anca Rothe

In this study we use high-speed photography as a feedback mechanism for adjusting the Nanodrop instrument dispense settings to improve the positional dispense accuracy of low volume (nanoliter) drops. These same parameters can be investigated, with various fluid classes, to reduce deleterious effects on dispensing performance such as deflected streams, satellite formation, secondary pulses and drop deformation.

Detection of Genetically Modified Organisms Using DNA Microarrays
Jaroslava Ovesna, Katerina Demnerova and Lucie Vistejnova

With the increasing production of genetically modified organis ms (GMOs ), the quick detection syst em is required. Microarrays offer a suitable and time saving method. Our aim is to develop DNA microarrays for detection of GMOs.

Gene Expression in Cold-stressed Barley as Detected by Microarray Analysis
J. Ovesná, B. Svejkovská, L. Kuèera, M. Malý, M. Herbstová and L. Cattivelli

Goal of this work is to find genes in spring and winter barleys that are influenced by cold stress and to analyze their expression profiles during stress. A few of experiments reported influence of temperature on the leaves and crown nodes, that is why we focus our study also on crown nodes by microarray technology.
