New micro-spectroscopic methods at ISAS Berlin
ISAS Berlin has a new application lab: In a three-year project, ISAS scientists have developed novel micro-spectroscopic methods to characterize ultrathin layers with higher spectral range, resolution and sensitivity and time-dependent processes with better temporal resolution. The project titled "New concepts for vibrational spectroscopy on nanoscopic materials" was funded by the state Berlin from the European Funds for Regional Development (EFRE).
The scientists were able to set up a Raman microscope at ISAS that covers a much wider spectral area than similar commercialized devices. They also installed an infrared microscope that is now used to analyze ultrathin layers, such as in functional surfaces. Also, a novel Echelle spectrograph for parallel detection of the MIR spectrum (mid-infrared) was developed and successfully tested; it can be coupled to the microscope platform and provides a temporal resolution in the range of milliseconds.
This combination of methods will permit new applications in microfluidics and on biosensors as well as investigations on semiconductor nanostructures or the marker-free detection of organic molecules. The efficiency of the measure concepts has already been demonstrated on organic and anorganic nanofilms. Capturing extremely fast time-dependent processes is especially important for bioanalytics and ohysical chemistry.
In addition to applications in basic research, a commercialization of the measure concepts is planned.
