Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs. Different mappings are established between various models of spiders and simple exclusion processes. For spiders with simple gait and varying number of legs we compute the diffusion coefficient; when the hopping is biased we also compute their velocity.

一维分子蜘蛛


分子蜘蛛是合成的生物分子系统，其“腿”由短的单链 DNA 片段组成。蜘蛛在覆盖着与腿互补的单链 DNA 片段的表面上移动。在各种蜘蛛模型和简单的排除过程之间建立了不同的映射。对于具有简单步态和不同腿数的蜘蛛，我们计算扩散系数；当跳跃有偏差时，我们还计算它们的速度。
