DNA microarray - Wikipedia
WEBA DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.

Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.
Illumina Microarray Technology
WEBHow Do Illumina Microarrays Work? As DNA fragments pass over the BeadChip, each probe binds to a complementary sequence in the sample DNA, stopping one base before the locus of interest. Allele specificity is conferred by a single base extension that incorporates one of four labeled nucleotides.
DNA chips: a new tool for genetic analysis and diagnostics
WEBJun 1, 2001 · DNA chips are miniaturized microsystems based on the ability of DNA to spontaneously find and bind its complementary sequence in a highly specific and reversible manner, known as hybridization. Labeled DNA molecules in a sample are analyzed by DNA probes tethered at distinct sites on a solid support.
