<p><b>New page</b></p><div>'''Microarray''' is a laboratory tool used to detect the expression of thousands of genes at the same time. DNA microarrays are microscope slides that are printed with thousands of tiny spots in defined positions, with each spot containing a known DNA sequence or gene.<br />
<br />
== History ==<br />
The concept of a microarray was first introduced by [[Patrick O. Brown]] in 1995. The technology was developed in response to the need for a more efficient method of identifying and measuring gene expression.<br />
<br />
== Types ==<br />
There are two main types of microarrays: [[cDNA microarrays]] and [[oligonucleotide microarrays]]. cDNA microarrays are made by spotting samples of cDNA onto a glass slide, while oligonucleotide microarrays are made by synthesizing short oligonucleotide sequences directly onto the slide.<br />
<br />
== Applications ==<br />
Microarrays have a wide range of applications in biological research and medicine, including gene expression profiling, comparative genomic hybridization, and single nucleotide polymorphism analysis. They are also used in the study of [[cancer]], [[infectious diseases]], and [[genetic disorders]].<br />
<br />
== Advantages and Disadvantages ==<br />
The main advantage of microarrays is their ability to analyze the expression of many genes simultaneously. However, they also have several disadvantages, including the high cost of the equipment and the complexity of data analysis.<br />
