Title: microarray
Long Title: IUPAC Gold Book - microarray
DOI: 10.1351/goldbook.09659
Status: current

Definition
Two-dimensional arrangement of a device for analysis of sub-microlitre sample volume.

Notes
1) This screening format is a direct offshoot of genomic microarray technologies and makes use of ultra-low-volume miniaturization provided by nanodispensing technologies.
2) A collection of molecules spatially addressed on a surface within features that have micrometer dimensions. Planar device (flat plane) used for off-line determination and identification of biocompounds.

Example
As a multiplex lab-on-a-chip, it can be used as an analytical device to measure the mRNA abundance (gene expression) of thousands of genes in one experiment binding the immobilised DNA fragments.
