Imaging ellipsometry in biotechnology

The imaging ellipsometer I-Elli200 from Nanofilm is a versatile tool to analyze biochips without any labeling of the probes. You can examine the surface structure of biological macro-molecules, e. g. DNA and proteins, on substrates like glass, silicon or gold with high spatial resolution. Due to real-time data acquisition it is possible to measure absorption reactions by using diverse solid-liquid cells for in vitro conditions. Imaging ellipsometry gives you the opportunity to measure the thickness of multiple spots simultaneously and to monitor hundreds of reaction channels in parallel. This makes the in-strument perfectly suited for high throughput screening (HTS).
