Cell experiments with optical tweezers are revolutionising biomedicine

Tweezing without touching - von Robert Meissner, Christina Alpmann, Álvaro Barroso, Prof. Dr. Cornelia Denz

Ultramodern imaging techniques such as the Nobel Prize-winning STED micro­scopy enable the investigation of organisms, cells, bacteria and even viruses, DNA or individual molecules at very high spatial and temporal resolution. Active intervention in these tiniest of biological structures has been largely limited to indirect methods, however. While new developments such as microtweezers and micromechanical clamps are promising, these devices generally...

Raman spectroscopy for biologists and clinicians

Photons on duty for health - von Dr Karin Schütze

Spectroscopy the bugbear for medical students and technicians: Asked by biologists or clinicians what exactly we are doing at CellTool® we originally answered, that we are developing a unique spectroscopic microscope system that enables easy cell analysis based on Raman spectroscopy. The two “non-words” in the world of biomedical scientists namely spectroscopy and Raman immediately caused to raise hackles and one could see how interest vanished....

The earliest plasma marker for myocardial infarction

Fabulous FABP - von Prof Dr Reinhard Renneberg, Prof. Dr Jan F.C. Glatz

The application of Fatty Acid-Binding Protein (FABP) as a plasma marker for the diagnosis of acute myo­cardial infarction was first suggested in 1988. Currently, FABP is proven to have added value for the diagnosis­ of patients presenting with chest pain suggestive of myocardial infarction, especially in the early hours after onset of symptoms. The routine application of FABP for this purpose not only will improve patient outcome but also markedly...
