论文摘要

双价赋予了几种浓度依赖性现象,包括亲戚,竞争交流和多站点竞争交流。由于这些概念对于细胞和分子生物学中的各种主题至关重要,因此它们的扩展,修改和/或重新修复对于纳米级的De-Novo合成系统的设计和构建也越来越重要。在这种情况下,我们借鉴了统计物理学的经典技术来重新审视双价性,强调了受体位点几何形状提供了独立于单个结合接口本身的化学反应的设计方式。根据多体协调重新塑造了问题,我们探索了受体位点的扩展,翻译不变的链和晶格。这不仅使与简单基序相关的行为具有清晰度,而且还使我们能够在合成软系统中依赖浓度依赖性动力学的合理设计核心原则,这是基于几何挫败感的概念。在这样做的过程中,我们还揭示了其他可调时空特征的可能性,例如相关长度,于点的位移和渗透样过渡。

Bivalency confers several concentration-dependent phenomena, including avidity, competitive exchange and multi-site competitive exchange. Since these concepts are crucial for a wide variety of topics in cell and molecular biology, their extension, modification and/or re-purposing is also increasingly important for the design and construction of de-novo synthetic systems at the nanoscale. In this context, we draw upon classical techniques of statistical physics to revisit bivalency, highlighting that receptor site geometry offers a design modality independent of the chemistry of the individual binding interfaces themselves. Recasting the problem in terms of many-body coordination, we explore extended, translationally-invariant chains and lattices of receptor sites. This not only brings clarity to behaviours associated with simpler motifs, but also enables us to distil core principles for the rational design of concentration-dependent kinetics in synthetic soft-systems, which centre on the notion of geometric frustration. In doing so, we also reveal the possibility of other tunable spatio-temporal features, such as correlation lengths, mean-squared displacements and percolation-like transitions.
