In this episode, Dr. Gu delves into the world of microcargoes and how their transport is integral for both living organisms and various applications in microrobotics, nanotechnology, and biomedicine. Current delivery technologies often face challenges in terms of speed, navigation control, and dispersal by cardiovascular flows. But, as Dr. Gu explains, these problems are largely addressed by cytoskeletal motors in cell biology that carry vesicles along microtubule highways.

Inspired by this biological mechanism, Dr. Gu presents his team's groundbreaking development of artificial microtubules (AMTs), which are structured microfibers embedded with micromagnets. These micromagnets serve as stepping stones to guide particles quickly through flow networks.

Dr. Gu details how this new method facilitates microcargo travel at speeds an order ...
