Researchers from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences have developed a hand-shaped 3D microrobot with a diameter of 40 millimeters to achieve precise movements such as grasping, delivering and releasing particles or cells.
According to the researchers, microrobots play a crucial role in early diagnosis and precision medicine, amid increasing demands for controllability in biomedicine and micromanipulation. They proposed making a multi-material, multi-modular hand-shaped microrobot based on femtosecond laser direct writing technology, which features a pH-sensitive capture unit and a magnet-sensitive transfer unit.
This robot can avoid obstacles and target molecules and cells.
The researchers expect that the microrobot will be used to control cells and deliver drugs objectively for precision therapy and in the field of environmental treatment.
