There are disclosed compositions and methods to render nucleic acids resistant to nuclease digestion while maintaining sequence selective hybridization competency. The approach relies on utilizing nucleic acids as the polar head group of a nucleic acid-polymer amphiphile in order to assemble well-defined, discrete micellar nanoparticles. Dense packing of nucleic acid in the micelle corona allows for hybridization of complementary oligonucleotides while prohibiting enzymatic degradation.
本文披露了一种使核酸在维持序列选择性杂交能力的同时抵抗核酸酶消化的组合物和方法。该方法依赖于利用核酸作为核酸-聚合物两性分子的极性头基,以组装明确定义的离散胶束纳米粒子。在胶束包层中核酸的密集包装允许互补寡核苷酸的杂交,同时禁止酶降解。
