DGIST recently announced that Professor Hongsoo Choi's team in the Department of Robotics Engineering developed a 'scaffold microrobot for stem cell delivery and transplantation,' which can further enhance the existing treatment efficiency of stem cell. A joint international research was conducted with Senior Researcher Jin-young Kim at DGIST-ETH Microrobot Research Center, Professor Seong-Woon Yu and Professor Cheil Moon's team in the Department of Brain and Cognitive Sciences, Professor Sung Won Kim's team in Seoul St. Mary's Hospital, and Professor Bradley J. Nelson's team in the Institute of Robotic and Intelligent Systems at ETH, Zurich, Switzerland.

Stem cell treatment has been taking limelight as a regenerative medical technique for intractable disorder treatment, but it cannot transplant the exact amount of stem cells to the target areas in need of treatment deeply inside body or may carry injection risk. It has especially been pointed out that treatment efficiency and safety are low due to huge loss during the in vivo delivery of stem cells and a high cost of treatment.

Limitation - DGIST - Research - Team - Microrobot

To overcome such limitation, the DGIST research team devised scaffold microrobot in a spherical and helical type through the 3D laser lithography2. The biggest achievement of this study is that it minimized cell loss in the body through a wireless control method using an external magnetic field while transplanting stem cells quickly and precisely at the same time.
