Analytica 2008
With 121 high level lectures and 65 published posters, Analytica 2008 – organised by the German Chemical Society (GDCh), the Society for Biochemistry and Molecular Biology (GBM) and the German United Society of Clinical Chemistry and Laboratory Medicine (DGKL) – was again a notable bio-chemistry event.
The trend towards automation was keenly discussed, in terms of costs and competitive needs. It was observed that this promotes increasing investments in (semi)-automated systems, and that automation is also called for when development is heading from laboratory analytics towards process analytics. Automated sample handling, for instance, not only guarantees a high capacity of samples but also facilitates fast and reliable online diagnostics for different substances. This in turn results in increased importance of the interaction between technology and the respective software tools.
Nanobiotechnology in tumour diagnostics
More precise, quicker and cheaper laboratory analysis is promised due to a new type of technology — Immune-SERS-Microscopics — developed by researchers at the Institute for Physical Chemistry at Würzburg University, which is currently awaiting patent. In this, gold nanoparticles of a certain shape and size are covered with a layer of organic molecules (Raman markers).
This is protected by a layer of glass coated with different ligates such as antibodies. These respectively bind to specific biomolecules, such as those in blood samples. Through exposure to laser light these give off characteristic signals which can then be detected. The method allows the determination of type and number of many different biomolecules at the same time, which facilitates, for example, more exact tumour analysis and therefore improved, individual therapy – faster and less costly than previously.

Accu-Chek® Combo – put effective diabetes management into action
At the annual congress of the European Association for the Study of Diabetes (EASD) this year in Rome, Roche Diabetes Care introduced Accu-Chek Combo – the insulin pump system that combines an insulin pump with an intelligent glucose monitoring system, a bolus calculator, and an integrated pump remote-control.
Insulin in oral capsules
At the international congress on diabetes in September, Oramed Pharmaceuticals, Inc. introduced its oral insulin capsules that might in the future replace injections patients currently have to face. Last week Oramed announced the agreement with ETI Karle Clinical Pvt. Ltd. to conduct phase 2B clinical trials for its oral insulin capsules.
Carestream: technical infrastructure for EU funded R-bay project
Carestream Health is a major technical infrastructure provider to the EU-funded R-Bay validation project, which aims to address the uneven spread of radiologists across member states. CARESTREAM Radiology and Information Management Solutions are driving the initial test platform for the project by facilitating remote reporting of images from hospitals in Denmark, Finland and Czech Republic by clinical providers in Estonia, Lithuania and the Netherlands.
