能够通过利用其环境的化学自由能产生自身动力的小规模合成马达代表了开发实用纳米机器的重要一步。催化颗粒能够产生浓度和其他梯度，可用于自推进小物体。然而，催化纳米颗粒通过自生力的自主运动是胶体和界面化学中相对未探索的领域。本文探讨了潜在的催化自生力推进小物体通过流体。
Small-scale synthetic motors capable of generating their own motive forces by exploiting the chemical free energy of their environment represent an important step in developing practical nanomachines. Catalytic particles are capable of generating concentration and other gradients that can be used to self-propel small objects. However, the autonomous movement of catalytic nanoparticles by self-generated forces is a relatively unexplored area in colloid and interfacial chemistry. This paper explores the potential of catalytically self-generated forces for propulsion of small objects through fluids.
