Development of magnetic microrobots for three-dimensional cell culture
DGIST announced on August 6th that research team led by Dr. Hongsoo Choi(Assistant Professor, Robotics Engineering, DGIST) developed a magnetic microrobots for three-dimensional cell culture and targeted transportation jointly with Dr. Cheil Moon(Associate Professor, Brain Science Engineering, DGIST), Dr. Li Zhang(Assistant Professor, Mechanical and Automation Engineering, The Chinese University of Hong Kong), and Dr. Bradely Nelson(Professor, Robotics and Intelligent Systems, ETH-Zürich).
The microrobot has full three-dimensional porous structures which are fabricated with an SU-8 photoresist using a 3D laser lithography system. Nickel and titanium are deposited as a magnetic material and biocompatible material respectively.
This new type of microrobot can deliver drugs to targeted body organs, and is expected to be used for the treatment of dementia or retinitis pigmentosa patients. Also accurate control of amount of drug and area targeting is possible with this type of microrobot, therefore prevention of side effects caused by drug overdose is expected. President Sung-Chul Shin said, "The development this time is the result of DGIST"s effort for achieving excellence through MIREBraiN program. DGIST will extend research on medical robotics through convergence among majors and cooperation with world"s renowned institutes."
