Abstract

Abstract : A fast two-stage hydrogel rocket is described that displays efficient autonomous motion, long transportation time and the release of Janus micromotors that can self-propel after hydrogel disintegration. Such an attractive two-stage hydrogel rocket holds considerable potential for the on demand delivery of artificial small motors and further diverse applications of nano/micro machines. Abstract : The development of autonomous micro/nano-scale objects has drawn considerable attention in recent years. Here we describe a two-stage hydrogel rocket that displays promising autonomous motion with a propelling speed of over 20 mm s −1 and more remarkably achieves a long transportation period and the release of self-propelled Janus micromotors. Such an attractive hydrogel rocket holds great potential for the protected delivery of active cargoes and future diverse applications of nano/micro machines.
