Key points from article :
Microrobotic agents can form swarms of targeted drug delivery for improved imaging analyses.
Researchers deviated from the typical process of drug therapy to facilitate swarm embolization.
Embolization 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.
They developed an actuation strategy to regulate magnetic particle swarms for selective embolization.
Actuation strategy provides a potential solution for selective embolization in the clinic to prevent complications arising via non-selective embolization mechanisms.
The study is published in Science Advances and carried out at the University of Toronto and Shanghai University.
