A microarray is a multiplex lab-on-a-chip. It is a 2D array on a solid substrate (usually a glass slide or silicon thin-film cell) that assays large amounts of biological material using high-throughput screening miniaturized, multiplexed and parallel processing and detection methods. The concept and methodology of microarrays was first introduced and illustrated in antibody microarrays (also referred to as antibody matrix) by Tse Wen Chang in 1983 in a scientific publication and a series of patents.〔http://www.google.com/patents/US4591570; http://www.google.com/patents/US4829010; http://www.google.com/patents/US5100777.〕 The "gene chip" industry started to grow significantly after the 1995 Science Paper by the Ron Davis and Pat Brown labs at Stanford University. With the establishment of companies, such as Affymetrix, Agilent, Applied Microarrays, Arrayit, Illumina, and others, the technology of DNA microarrays has become the most sophisticated and the most widely used, while the use of protein, peptide and carbohydrate microarrays are expanding. Types of microarrays include: *DNA microarrays, such as cDNA microarrays, oligonucleotide microarrays, BAC microarrays and SNP microarrays *MMChips, for surveillance of microRNA populations *Protein microarrays *Peptide microarrays, for detailed analyses or optimization of protein-protein interactions *Tissue microarrays *Cellular microarrays (also called transfection microarrays) *Chemical compound microarrays *Antibody microarrays *Carbohydrate arrays (glycoarrays) *Phenotype microarrays *Reverse Phase Protein Microarrays, microarrays of lysates or serum * interferometric reflectance imaging sensor (IRIS) People in the field of CMOS biotechnology are developing new kinds of microarrays. Once fed magnetic nanoparticles, individual cells can be moved independently and simultaneously on a microarray of magnetic coils. A microarray of nuclear magnetic resonance microcoils is under development. ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「microarray」の詳細全文を読む スポンサード リンク
