Introduction: DNA Microarrays – Ten Years Old, but no Old Hat Falk Hertwig and Ulrike A Nuber

In October this year, we celebrate the 10th anniversary of DNA microarrays, as this technology was first mentioned in an article by Schena, M., Shalon, D., Davis, R.W., and Brown P.O. published in the ‘Genome Issue’ of Science in 1995 (1). Predecessors of this technology were dot blots, slot blots, and macroarrays with membranes used as platform. Microarrays have been fascinating the scientific community for the last decade, but still have not reached the limits of their potential and are continuing to invade new fields of biology and medicine.
