The new paper Sperm Micromotors for Cargo Delivery through Flowing Blood

by Haifeng Xu, Mariana Medina-Sánchez, Manfred F. Maitz, Carsten Werner and Oliver G. Schmidt presents a hybrid sperm micromotor that can actively swim against flowing blood (continuous and pulsatile) and perform the function of heparin cargo delivery. In this biohybrid system, the sperm flagellum provides a high propulsion force while the synthetic microstructure serves for magnetic guidance and cargo transport. Moreover, single sperm micromotors can assemble into a train-like carrier after magnetization, allowing the transport of multiple sperm or medical cargoes to the area of interest, serving as potential anticoagulant agents to treat blood clots or other diseases in the circulatory system. The paper was published in ACS Nano.
