Dresden and some other regions of Saxony play a leading role in some areas of international biotechnology, such as electronic bioengineering. While these high-technology sectors do not yet offer a large number of jobs, they have stopped or even reversed the brain drain that was occurring until the early 2000s in many parts of Saxony.
