A tubular micromotor with spatially resolved compartments is presented toward efficient site‐specific cargo delivery, with a back‐end zinc (Zn) propellant engine segment and an upfront cargo‐loaded gelatin segment further protected by a pH‐responsive cap. The multicompartment micromotors display strong gastric‐powered propulsion with tunable lifetime depending on the Zn segment length. Such propulsion...
Virus‐like nanoparticles (VLPs) have been used as an attractive means in cancer immunotherapy because of their unique intrinsic immunostimulatory properties. However, for treating metastatic tumors in the peritoneal cavity, such as ovarian cancer, multiple injections of therapy are needed due to the large peritoneal space and fast excretion of therapy. Here, it is reported on the development of active...
While synthetic micromotors have been evaluated extensively under in vitro conditions for over a decade, their in vivo function has rarely been explored. Recent research effort has resulted in micromotors that display fast movement in complex biological media, and possess efficient cargo loading, transport, and release, along with good biocompatibility. These new capabilities have made synthetic micromotors...
