基因芯片技术是20世纪90年代末兴起的一项前沿生物技术。它是指将大量靶基因或寡核苷酸片段有序地高密度地排列固定于玻片、硅片等固相载体上,然后与待测的标记样品的基因按碱基配对原理进行杂交,通过激光共聚焦荧光检测系统等对芯片进行扫描,再经计算机软件处理,从而获取大量生命信息。自从1995年美国斯坦福大学的Schena和Brown Gene chip technology is a leading edge biotechnology that emerged in the late 1990s. It refers to a large number of target genes or oligonucleotide fragments ordered high-density arrayed on glass slides, silicon wafers and other solid-phase carrier, and then with the marker samples to be tested according to the principle of base-pairing hybridization, Through the laser confocal fluorescence detection system to scan the chip, and then processed by computer software to access a large number of life information. Since 1995 Schena and Brown at Stanford University in the United States
