Microrobotic agents can form swarms of targeted drug delivery for improved imaging analyses. In a new report now published in Science Advances, Junhui Law and a team of researchers in mechanical and industrial engineering, artificial intelligence and biomedical engineering at the University of Toronto and the Shanghai University, China, deviated from the typical process of drug therapy to facilitate swarm embolization. The process is a medical technique used to block blood vessels during treatment for thrombosis and arteriovenous malformations. Magnetic particle swarms offer more precise embolization and can maintain swarm integrity inside a targeted region under fluidic flow conditions. Based on experiments in microfluidic channels, ex vivo tissues and in vivo porcine kidneys, Law and the team validated the efficacy of the proposed strategy for selective embolization.
