Abstract
DNA microarrays represent a hybridization-based high-throughput technology for the analysis of gene expression, polymorphisms, or mutations. The microarrays are formed from thousands of DNA probes, which are immobilized onto a solid surface as microscopic spots and used to hybridize DNA samples. The principle, the fabrication, and the experimental procedures of microarrays are described in this chapter. Applications of microarray technology for the detection of foodborne pathogens are also summarized.
