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.
Usage examples of "microarray".
The microarray slides are read automatically by laser scanners, and the results, thanks to Bioinformatics, are fed directly into computers armed with appropriate software such that risk and hence cost can be predicted with rapidly advancing speed and accuracy.
DNA microarrays because these devices make it possible to take a kind of snapshot of a cell, and see which genes are turned on and which are turned off.
The system is based on thumbnail-size glass chips called microarrays that are coated with a thin layer of so-called cDNAs, which represent all the mRNAs made by a particular type of cell.
