Game changers in the field of miniature robots

□ minimally invasive robot^[1] targeted precision therapy can be manufactured
in a variety of ways.

□ In order to overcome the limitations of existing micro-robot manufacturing methods, the research team of Professor Cui Hongsu of Nanjing University of Technology has developed a method to manufacture microrobots at a rate of 100 per minute by flowing a mixture of magnetic nanoparticles and biodegradable and light-curable gelatin methacrylate into a microfluidic chip
.

□ micro-robots prepared with this technology are cultured with human turbinate stem cells collected from human noses, and induced stem cells adhere to the surface
of the micro-robots.

□ in the case of existing stem cell therapy, selective cell delivery is difficult
.

□ addition, stem cells carrying microrobots are cultured with degrading enzymes to evaluate the degradation of microrobots
.

□ addition, the team also confirmed whether the stem cells delivered by the microrobots have normal electrophysiological properties
.

Hongsoo Choi, a professor at DGIST at □, said: "We expect that the technologies developed through this research, such as the mass production of micro-robots, the precise operation of electromagnetic fields, and the transmission and differentiation of stem cells, will greatly improve the efficiency
of targeted precision therapies in the future.
