Microrobots for cell and drug delivery in the human body

See on Scoop.itMedicine in Pictures

The development of microrobots requires interdisciplinary knowledge including mechatronics, materials science, biology, computing and automation. These tiny devices have the potential to work in very small and confined spaces and thus have broad applications in many fields, but particularly in minimally invasive medical treatment.

 

Prof. Zhang Li, from CUHK’s Department of Mechanical and Automation Engineering, collaborated with Daegu Gyeongbuk Institute of Science and Technology (DGIST) in Korea, and ETH Zurich. Together, they innovated a new microrobot capable of transporting the appropriate amount of cells and therapeutic drugs to specific areas of the body. The team used laser lithography to construct porous 3D scaffolds which were coated with a thin layer of magnetic material (nickel) and biocompatible material (titanium). This allowed remote manipulation of the devices using external magnetic fields to guide them, while causing no harm to living cells.
