Selected Papers from 2017 International Conference on Micro/ Nanomachines

The 2017 International Conference on Micro/Nanomachines (http: //www.icmnm.org/) was held in Wuhan China 25-28 August 2017. Micro/nanomotors (MNMs) which are defined as micro/nanodevices capable of converting energy into autonomous motion can be used to pick up transport and release various cargoes within a liquid medium. They have important potential applications for example in drug delivery biosensors protein and cell separation microsurgeries and environment remediation. MNMs can be classified into two categories according to their propulsion mechanism. In this respect self-propelled MNMs are capable of moving autonomously without external intervention but they either require toxic fuel or have a short lifespan. MNMs actuated by external fields such as light magnetic field and acoustic waves are not subject to these problems do not require toxic fuels nor give rise to by-products during the motion process. For both self-propelled and field-actuated MNMs there is still a long way to go before we reach practical applications. The future development of MNMs should be focused on improving the energy conversion efficiency through structure optimization exploring new propulsion mechanisms and endowing MNMs with environmental responses for self-navigation detection and specific operations. In this way MNMs will approach their practical application in biomedicine environment treatment microengineering etc.
