Magnetically-Powered Micro-Train

CSEF · 2023 Materials Science Fourth Award

Chen Steven · 7

Overview

This project aims to develop a magnetic micro-train that can be remotely controlled by an external magnetic field to carry and release drugs to a targeted location to fight against diseases. To fabricate the micro train, the first step was to create a PDMS mold for the train with 3D printing. Next, a hydrogel mixture, consisting of PEGDA hydrogel and magnetic nanoparticles, was used for the train head. As a mock payload, green food dye was added to the hydrogel mixture for the train cargo to demonstrate the release of drugs. Then, through UV polymerization, the micro-train was solidified in the mold and then released for testing. The results showed that the magnetic micro-train could be guided by an external magnet, and the food dye carried by the magnetic micro-train diffused away in 12 hours. In conclusion, a magnetically controlled micro-train could be a powerful tool for targeted drug delivery.
