寡核苷酸是短的、单链或双链的DNA或RNA分子。其合成方法发展历程：从Michelson和Todd早期的H-磷酸盐和磷酸三酯法（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）和亚磷酸三酯法（Phosphite triester）的发展。而直至1980年代，Marvin Caruthers的亚磷酰胺法（Phosphoramidite），加上自动化固相技术，成为了目前主流的寡核苷酸合成技术方法。在聚合酶链反应(PCR)、核酸测序、基因检测、核酸药物研发等领域有广泛应用。
亚磷酰胺寡聚体的合成在3'-5'方向进行(与生物合成中DNA复制的5'-3'方向相反)。每个合成周期添加一个核苷酸。亚磷酰胺DNA合成循环如图所示。
