Micro and nanotechnologies are revolutionising medicine
'Almost invisible' tools are being developed by European researchers to discover diseases earlier and to treat patients better. At the same time the miniaturisation of instruments to micro- and nano-dimensions promises to make our future lives safer and cleaner. In Barcelona, Spain, a leading European research group (Centro Nacional de Microelectronica in Bellaterra) is developing a low-cost molecular detection tool: the "Biofinger". The tiny chips can detect a huge variety of substances, from cancer cells to chemical ingredients. The revolutionary idea is to use physical forces in nano-dimensions in order to search for molecules. A team of European researchers from the Fraunhofer Institute for Biomedical Technologies institute near Saarbruecken is using nanotechnology to improve diagnostic capabilities. In the "Adonis"-project, nano-sized gold particles are used to detect prostate cancer cells at an early stage.
