The chemotactic movement of decanol droplets in aqueous solutions of sodium decanoate in response to concentration gradients of NaCl has been investigated. Key parameters of the chemotactic response, namely the induction time and the migration velocity, have been evaluated as a function of the sodium decanoate concentration and the NaCl concentration gradient. The ability of the decanol droplets to migrate in concentration gradients has been demonstrated not only in a linear chemotactic assay but also in a topologically complex environment. Additionally, the ability to reverse the direction of movement repeatedly, to carry and release a chemically reactive cargo, to select a stronger concentration gradient from two options, and to initiate chemotaxis by an external temperature stimulus have been demonstrated.
已对癸醇液滴在癸酸钠水溶液中响应NaCl浓度梯度的趋化运动进行了研究。趋化反应的关键参数,即诱导时间和迁移速度,已作为癸酸钠浓度和NaCl浓度梯度的函数进行了评估。癸醇液滴在浓度梯度中迁移的能力不仅在线性趋化分析中得到了证明,而且在拓扑复杂的环境中也得到了证明。此外,还证明了其具有反复逆转运动方向、携带和释放化学反应性货物、从两个选项中选择更强浓度梯度以及通过外部温度刺激引发趋化作用的能力。
