游动微纳米机器人在靶向治疗、生物传感器、药物载体等方面的潜在医学应用引起了研究人员的兴趣。目前，游泳微纳机器人的实验设置主要是在纯水或H2O2溶液中进行研究。介绍了一种以人体体液中的葡萄糖为驱动燃料的微纳机器人。基于葡萄糖燃料电池正极材料的催化性能，分别选择铂（Pt）和碳纳米管（CNT）作为微纳机器人的正极材料。该创新设计采用模板电化学和化学气相沉积的方法来制造Pt/CNT微纳机器人结构。采用扫描电镜（SEM）和透射电镜（TEM）观察样品的形貌，并用能量色散x射线能谱（EDX）分析样品中的元素。通过在葡萄糖溶液中进行大量实验，根据斯托克黏性力定律和牛顿第二定律，计算了所制备的微纳机器人的驱动力。结果表明，Pt/CNT微纳米机器人的结构满足生物相容性和运动特性的要求。
Swimming micro-nanorobots have attracted researchers' interest in potential medical applications on target therapy, biosensor, drug carrier, and others. At present, the experimental setting of the swimming micro-nanorobots was mainly studied in pure water or H2O2 solution. This paper presents a micro-nanorobot that applied glucose in human body fluid as driving fuel. Based on the catalytic properties of the anode and cathode materials of the glucose fuel cell, platinum (Pt) and carbon nanotube (CNT) were selected as the anode and cathode materials, respectively, for the micro-nanorobot. The innovative design adopted the method of template electrochemical and chemical vapor deposition to manufacture the Pt/CNT micro-nanorobot structure. Both the scanning electron microscope (SEM) and transmission electron microscope (TEM) were employed to observe the morphology of the sample, and its elements were analyzed by energy-dispersive X-ray spectroscopy (EDX). Through a large number of experiments in a glucose solution and according to Stoker's law of viscous force and Newton's second law, we calculated the driving force of the fabricated micro-nanorobot. It was concluded that the structure of the Pt/CNT micro-nanorobot satisfied the required characteristics of both biocompatibility and motion.
