Exploring new frontiers of colloidal science: active colloids

点击翻译按钮获取中文摘要

Active colloidal particles are micro/nano sized particles which are able to self-propel in fluids. Their ability to “swim” makes them interesting for new technological applications ranging from cargo particles for drug delivery to model suspensions to recreate synthetically the behaviour of biological systems. They may also display collective motion, similar to that commonly seen in nature, from swarming phenomena in bacterial colonies to flocks of birds or fish.
