2D Molecule Tracking — •Benjamin Greiner, Thorsten Pieper, and Harald Mathis — Fraunhofer Gesellschaft, IZB, BioMIP

2D Molecule Tracking focusses on the spatially and temporally resolved detection of biomolecules in solutions on the nanometer scale. With the help of fluorescence microscopy and fast parallel photon processing units (FPGA-technologies) it is possible to observe the trajectories of small DNA molecules. The 2D observation of single particles and molecules can be an important tool for understanding biochemical processes in cells. Our MolTracker consists of an open microscope, an Image Intensifier built by LaVision (G"ottingen) and a 2D strip detector based on an adapted nuclear physics device from the Physical Institute of the University of Bonn and configurable parallel hardware. Present research in associated projects is done aiming at the manipulation of molecules in microstructured reactors.
