Engines and motors are everywhere in the modern world, but it is a challenge to make them work if they are very small. On the micron length scale, inertial forces are weak and conventional motor designs involving, e.g., pistons, jets, or flywheels cease to function. Biological motors work by a different principle, using catalysis to convert chemical to mechanical energy on the nanometer length scale. To do this, they must apply force continuously against their viscous surroundings, and because of their small size, their movement is “jittery” because of the random shoves and turns they experience from molecules in their surroundings.

两种力量胜过一种力量：化学和声学推进相结合，增强了微电机的功能

发动机和电动机在现代世界中无处不在，但是如果它们很小的话，要使它们工作也是一个挑战。在微米长度尺度上，惯性力很弱，并且涉及例如活塞，喷头或飞轮的常规电动机设计不再起作用。生物马达以不同的原理工作，利用催化作用将纳米级的化学能转化为机械能。为此，他们必须不断对粘稠的环境施加力，并且由于它们的体积小，它们的运动“抖动”，这是因为它们从周围的分子中受到随机的推挤和转向。
