JPK announces the Nanotracker nano optics platform for applying optical tweezers and 3D particle tracking. It delivers live cell imaging, and the user can trap and track particles from several µm down to 30 nm with the ability to control, manipulate and observe vesicles, endosomes, gene and drug spheres, viruses and bacteria, nanoprobes or carriers, biomarkers or even whole cells in real time with nanometer precision. This opens up new applications in many different disciplines including biophysics, biochemistry, cellular and medical research in microbiology, developmental and system biology, infection research and immune response, toxicity of nanoparticles and many more. Applications are e.g. the study of single molecules & biopolymers, cell membranes, cell-particle interaction and viral and bacterial infection.
