ｃＤＮＡ阵列 (ｃＤＮＡａｒｒａｙ)或微阵列 (ｍｉｃｒｏａｒｒａｙ)是通过平面微细加工技术在固相表面构建的微流体分析单元和系统 ,它不但可高敏感地定量、定性检测基因表达水平 ,且其最大优点是彻底改变了传统的对单个或几个基因表达水平的研究 ,而可同时研究同一组织或不 cDNAarray or microarray are microfluidic analytical units and systems that are fabricated on planar surfaces using planar microfabrication techniques. They not only provide high-sensitivity quantification and qualitative detection of gene expression levels, but also their greatest advantage is thorough Has changed the traditional study of single or several gene expression levels, and can simultaneously study the same organization or not
