寡核苷酸是短的、單鏈或雙鏈的DNA或RNA分子。其合成方法發(fā)展歷程：從Michelson和Todd早期的H-磷酸鹽和磷酸三酯法（H-Phosphonate & Phosphotriester）；到1950年代Khorana的磷酸二酯法（Phosphodiester）；以及1960-1970年代的磷酸三酯法（Phosphotriester）和亞磷酸三酯法（Phosphite triester）的發(fā)展。而直至1980年代，Marvin Caruthers的亞磷酰胺法（Phosphoramidite），加上自動化固相技術(shù)，成為了目前主流的寡核苷酸合成技術(shù)方法。在聚合酶鏈反應(yīng)(PCR)、核酸測序、基因檢測、核酸藥物研發(fā)等領(lǐng)域有廣泛應(yīng)用。
亞磷酰胺寡聚體的合成在3'-5'方向進(jìn)行(與生物合成中DNA復(fù)制的5'-3'方向相反)。每個合成周期添加一個核苷酸。亞磷酰胺DNA合成循環(huán)如圖所示。
