研究了癸醇液滴在癸酸钠水溶液中对NaCl浓度梯度的趋化运动。的趋化反应，即诱导时间和迁移速度的关键参数，已被评估为癸酸钠浓度和NaCl浓度梯度的函数。癸醇液滴在浓度梯度中迁移的能力不仅在线性趋化性测定中得到证实，而且在拓扑复杂的环境中也得到证实。此外，已经证明了反复逆转运动方向、携带和释放化学反应性货物、从两种选择中选择更强的浓度梯度以及通过外部温度刺激启动趋化性的能力。
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.
