Roche unveils new nanotech diagnosis tool Tue Dec 5, 5:02 AM ET ZURICH (Reuters) - Swiss pharmaceutical group Roche Holding AG on Tuesday unveiled a new method using nanotechnology to track patients' responses to treatments by monitoring their genes. The new method detects active genes directly by using sensors attached to tiny silicon cantilevers which are only 450 nanometres thick and therefore react with extraordinary sensitivity, the company said. One nanometre is a millionth of a millimetre. "This promising new technology takes us a step nearer to tailoring treatment directly to patients' needs, hopefully with ever fewer adverse effects," Ulrich Certa, head of functional genomics at the Roche Center for Medical Genomics, said in a statement. The study was completed by researchers from Roche and the National Center of Competence in Research at the new Swiss Nanoscience Institute (SNI) in Basel, and published in the December issue of the journal Nature Nanotechnology. "Because the method also works within minutes, it could be used as a real-time sensor for continuously monitoring biomedical processes (and) for detecting rapidly replicating pathogens that make prompt diagnosis essential," Roche said.
