论文摘要
DNA介导的胶体颗粒之间的多价相互作用已广泛应用，以编程散装相行为和动态过程的能力。利用不同类型的DNA-DNA键之间的竞争，我们在这里实验证明了在存在官能化表面的情况下胶体自组装的选择性触发，从而诱导粒子粒子相互作用的变化。除了与厚度受控的分层材料的制造相关之外，提议的相互作用方案的固有信号放大特征使其对于生物传感应用很有价值。
DNA-mediated multivalent interactions between colloidal particles have been extensively applied for their ability to program bulk phase behaviour and dynamic processes. Exploiting the competition between different types of DNA-DNA bonds, here we experimentally demonstrate the selective triggering of colloidal self-assembly in the presence of a functionalised surface, which induces changes in particle-particle interactions. Besides its relevance to the manufacturing of layered materials with controlled thickness, the intrinsic signal-amplification features of the proposed interaction scheme make it valuable for biosensing applications.
