“纳米蜘蛛”机器人复制出了另一个机器人,继而被染成绿色,并朝红色目标移动
据《每日邮报》5月13日报道,美国哥伦比亚大学科学家近日成功研制出一种由DNA分子构成的“纳米蜘蛛”微型机器人,它们能够跟随DNA的运行轨迹自由地行走、
移动、转向以及停止,并且它们能够自由地在二维物体的表面行走。
据悉,这种“纳米蜘蛛”机器人的大小仅有4纳米,比人类头发直径的十万分之一还小。该“纳米蜘蛛”机器人的发明是对几年前“蜘蛛分子”机器人的改进与升级,其功能更加强大,这种纳米机器人不仅能够自由地在二维物体的表面行走,而且还能吞食面包碎屑。虽然以前研制出的DNA分子机器人也具有行走功能,但不会超过3步,而“纳米蜘蛛”机器人却能行走100纳米的距离,相当于行走50步。
“纳米”机器人可以用于医疗事业,以帮助人类识别并杀死癌细胞以达到治疗癌症的目的,还可以帮助人们完成外科手术,清理动脉血管垃圾,及组成计算机新硬件等。科学家们已经研发出这种机器人的生产线
