Over the last 15 years, the application of computers to microscopes has significantly enhanced the level of automation that is possible once a specimen has been inserted into the microscope. A long-standing bottleneck has been the automated delivery of multiple specimens into an electron microscope, and overcoming this has presented researchers with significant challenges.

The emergence of bioinformatics tools, which integrate molecular biology and genomics with computer based information technology, is bringing about a revolution in our understanding of the molecular mechanisms underlying normal and dysfunctional biological processes. The microarray is one such tool that caused a paradigm shift in the manner in which researchers collect and analyze genetic data.
