Can you imagine that the tiny nano machine which is invisible by our eyes can move quickly like fish and complete the tasks such as cell screening, drug targeting release? The new research “Fish-Like Nano Motors Driven by Magnetic Field” cooperated by two research teams led by professors Zhang Guangyu and Li Longqiu of electrical and mechanical college at HIT and professor Joseph Wang at University of California at San Diego respectively will make this scientific fantasy into reality.
The research “Fish-Like Nano Motor Driven by Magnetic Field” has been published in the latest, world-renowned, academic Journal “Small”(Influence factor 8.315) in micro-nano field, and has been selected as the front cover of the Journal. The first author is Li Tianlong, who is a 2012 doctoral student in HIT. Professor Li Longqiu who is the correspondence author. HIT is the first signed unit for the paper. The project is funded by the programs such as the National Natural Science Foundation, "111" engineering plan, technology of robotics and the opening project of State Key Laboratory.
“Fish can move quickly via self swing in water, and this research imitates this high-efficient movement mode to accomplish the quick movement of nano motors in fluid”. According to the professor Li Longqiu, the research has initially pushed forward this kind of fish-like nano motor driven by magnetic field in the world. The motor moves quickly by tail swing driven by alternating magnetic field. It transforms the outer magnetic field into mechanical energy, and the length of the motor is only 5 microns. Compared with chemical driving, the driving of this research has non-toxic side effects, depends less on the envionment and needs no extra refueling; compared with light driving, it has better controllability and penetrability; compared with ultrasonic driving, it has more precise direction control. The motor has bright future in many fields such as biological detection sensors, micro-nano device processing, micro nano robot and drug targeting release.
