DNA Microarrays: History and Overview

It may seem premature to be writing a history of DNA microarrays because this technology is relatively new and clearly has more of a future than a past. However readers could benefit from learning something about the technical basis of DNA microarrays, and younger readers may be curious to know something of the origins and antecedents of this new technology. In this chapter, I have attempted also a critical overview of the current state of the art.
