INTRODUCTION

Micro/nano-robotics is an emerging robot research field which combines with the special robotic technology.

Different from macroscopically visual robot, micro/nano-robots usually refers to the microscopic systems scale.

This topic mainly deals with the applications of micro/nano robotics in biomedical field and their limitations.

LIMITATIONS

Research is limited to single bionic structures. Accurate,continous and low dimensional contol is still a

challenge. Possible allergic reactions from patients towards nanorobots. Security and reliability. Needs research on functionalization and intelligence of

micro/nano materials.

39


CONCLUSION

Despite facing many challenges the future of nano robotics has irreplacable advantages of devolopment.

Currently, micro/nano-robotics has been applied to the aspects of molecular medicine, genetic engineering technology.

In addition, it has huge potential development directions in the future.
