Chemically powered nano-and micromotors are microscopic devices that convert chemical
energy into motion. Interest in these motors has grown over the past 20 years because they …

The use of tools can be traced back to the beginning of recorded history and represents a
significant step in the evolution of mankind. A machine is a tool that can perform intended …

Chemically powered micro‐and nanomotors are small devices that are self‐propelled by
catalytic reactions in fluids. Taking inspiration from biomotors, scientists are aiming to find …

Symmetric shapes and patterns are fascinating and preferred by humans as symmetric
stimuli of any kind are more easily processed by the visual systems than their asymmetric …

In this article we review the development, current status and future prospects of nano-and
microscale motors propelled by locally generated fields and chemical gradients. These …

The advent of autonomous self-propulsion has instigated research towards making colloidal
machines that can deliver mechanical work in the form of transport, and other functions such …

Inspired by highly efficient natural motors, synthetic micro/nanomotors are self-propelled
machines capable of converting the supplied fuel into mechanical motion. A significant …

It is well-known that micro-and nanoparticles can move by phoretic effects in response to
externally imposed gradients of scalar quantities such as chemical concentration or electric …

Although the concept of Janus particles was raised in the early 1990s, the related research
has not attracted considerable interest until recently due to the special properties and …

Nano-and micromotors are nano-and microscale devices, respectively, designed to perform
selected mechanical movements (eg, rotation, rolling, shuttling, delivery, contraction, and …
