Interviewee: Stephen Fodor. Stephen Fodor discusses the experiments that laid the groundwork for GeneChipâ„¢ technology. (DNAi Location: Applications > Genes and medicine > genetic profiling > Stephen Fodor > How the chip was developed-Part I)

Developing out the GeneChipâ„¢ technology was pretty much like everything else that's done in this world, it was through experimentation. And we had some wonderful ideas about how to do this, but the first real experiments were almost high school lab type experiments. We took the basic building blocks of nature, the A, C, G and T, prepared them in a way so that we could do chemical synthesis with them, but then the question was, how do you lay this out on a surface. And the first experiments in fact were to do very simple experiments, where for example we printed up checkerboards on a printer and then took a picture of that checkerboard, had the film developed and then used that film as a guide to, to describe which regions of the array would be illuminated and which ones would be dark.
