一项新研究指出,磁控微型机器人有朝一日或能帮助我们对抗癌症。在过去十年间,科学家证明了可以用磁力操控植入人体的医疗设备,如用磁场控制心脏导管、操控微型摄像头在肠道内穿梭等。此前的研究还能利用磁场同时操纵大量微型磁铁。从理论上来说,这些微型磁铁可用于解决癌症等严重健康问题。不过,如何单独控制一群微型设备中的某几个设备、让它们按照特定速度和方向运行,目前仍是一大挑 A new study points out that a microneedle robot may one day help us fight cancer. Over the past decade, scientists have demonstrated that magnetic devices can be used to manipulate medical devices implanted in the body, such as using a magnetic field to control a cardiac catheter and manipulating a micro-camera to shuttle through the intestine. Previous studies have also been able to manipulate large numbers of miniature magnets using magnetic fields. Theoretically, these miniature magnets can be used to solve serious health problems such as cancer. However, how to control a few devices in a group of micro-devices individually to run them at a specific speed and direction is still a big challenge
