We have developed a microfluidic chip that allows online haemostasis monitoring using a thickness shear mode sensor. The sensor allows the detection of adsorbed masses and changes in viscosity in real-time. The microfluidic mixer permits fast mixing of whole blood with activators, which trigger the coagulation cascade. Changes in frequency were measured during the coagulation of whole blood.

The model system used here is based on retroviral particles displaying tPA, a protein used in current emergency therapies of myocardial infarction and stroke. Single tPA variants were encapsulated into aqueous droplets, at a frequency of ~10Kilohertz and the enzymatic activity was monitored using a fluorescence assay. Active variants could be clearly distinguished from inactive variants or variants incubated with the endogenous inhibitor PAI-1.

Here we present a novel discovery-oriented high-throughput approach to the screening of allergen reactivates in crude biological extracts is presented using seafood allergens as an example. The CPGR workflow permits the effective screening of hundreds of putative allergens in parallel using minute amounts of patient serum and constitutes a cost-efficient allergen-specific antibody screening method for a routine diagnostic setting.

The aim of this study is to produce a vector capable of expressing green fluorescent protein (GFP) when exposed to a CYP1A1 inducer.

Bio-analytic silicon chips can be used to investigate stem cell differentiation into neurons and for the in vitro on-line monitoring of cellular reactions under well controlled experimental conditions. Chip systems allow for a parallel, label-free and non-invasive measurement of different parameters by CMOS silicon microsensors by the application of potential neurotoxic and developmental neurotoxic substances.

The EU chemical policy REACH, effective on June 2007, regulates the registration, evaluation and authorization of chemicals. Investigations on the effects of neurotoxic and developmental-neurotoxic substances are required by European and US-American test guidelines. However, at the moment these tests are based on animal experiments contradicting society claims to abolish animal experiments and to implement the 3R-principle. The resulting problem is… How to pair REACH and the 3Rs?

Microcosm BioBright slides (patent pending) are designed as a plug-and-play alternative to commercially available microarray substrates for use with different microarray platforms (oligo, miRNA or protein).

For final description of microarray experiment results it is necessary to use some statistically robust method. Transcription maps (TM) are used to map results of gene expression analysis into individual chromosomes. We have implemented graphical tool for interactive display of TMs. This tool allows displaying of arbitrary information for each gene.
