药物输送、微创手术和体内医院是满足纳米机器人快速增长需求的最佳选择。报道了一种Z型金/铂（Au/Pt）杂化纳米机器人，该机器人无需外力场即可实现自旋转运动。采用聚焦离子束（FIB）和等离子体溅射法制备了Z型Au/Pt杂化纳米机器人。通过能量色散X射线分析（EDS）测试纳米机器人的纯度。Pt和Au在尖端的重量百分比分别为94.28%和5.72%。底部Pt和Au的重量百分比分别为17.39%和82.75%。纳米机器人的尺寸为2.58 × 10−16 m2，质量为8.768 × 10−8 kg。在6.9%浓度的过氧化氢溶液下，纳米机器人的驱动力为9.76 × 10−14 N。在5.6%、6.2%和7.8%浓度下，转速分别为13 rpm、14 rpm和19 rpm。
Drug delivery, minimally-invasive surgery, and a hospital-in-the-body are highly desirable for meeting the rapidly growing needs of nanorobot. This paper reports a Z-shaped gold/platinum (Au/Pt) hybrid nanorobot which realizes the self-rotational movement without an external force field. The Z-shaped Au/Pt hybrid nanorobot was fabricated by focused ion beam (FIB) and plasma sputtering. The purity of the nanorobot was tested by energy dispersive X-ray analysis (EDS). The weight percentage of Pt and Au at the tip were 94.28% and 5.72%, respectively. The weight percentage of Pt and Au at the bottom were 17.39% and 82.75%, respectively. The size of the nanorobot was 2.58 × 10−16 m2 and the mass of the nanorobot was 8.768 × 10−8 kg. The driving force of the nanorobot was 9.76 × 10−14 N at the 6.9% concentration of hydrogen peroxide solution. The rotation speed was 13 rpm, 14 rpm, and 19 rpm at 5.6%, 6.2%, and 7.8% concentrations, respectively.
