DNA 在受限管道中的回复
关键字：：DNA 管道受限，回复，热力学
我们采用粗粒化 DNA 分子模型和副本交换分子动力学方法，研究了受限在管道中的两条单链 DNA 的回复行为，考察了受限对 DNA 回复热力学性质的影响。通过统计不同温度下的 DNA 碱基的配对数获得融解曲线，发现融解温度随着受限尺寸的减小而增大。热容曲线反映相似的规律：随着受限尺寸的减小，热容峰向高温方向移动，峰高逐渐降低，同时峰变宽。我们考察了四种不同的序列在不同受限条件下的...

Small 2007: Tunable film degradation and sustained release of plasmid DNA from cleavable polycation/plasmid DNA multilayers under reductive conditions
The controllable and sustained release of DNA from the surfaces of biomaterials or biomedical devices represents a new method for localized gene delivery. We report the synthesis of a novel polycation containing disulfide bonds in its backbone and the fabrication of polycation/plasmid DNA multilayered thin films by layer-by-layer assembly. The films are very stable during preparation and in storag...

DNA 自组装及诱导纳米金粒子组装
关键字：DNA 分支迁移反应，金纳米，自组装，DNA 反应网络
通过设计系列 DNA 分支迁移反应，构建 DNA 分子机器，并通过优化影响 DNA 分子机器运转的参数，使得机器运转与金纳米粒子组装同步进行，从而实现了由分子机器推动的金纳米粒子动态组装技术。使用这种新建立的方法，不仅可以调控金纳米粒子的组装速率和形态结构，更能通过设计不同的 DNA 催化链碱基序列实现逻辑运算。使用该技术有望制备具有复杂功能的纳米器件，拓宽其应用范围。
