Nano/micromotors (NMs) are tiny structures capable of converting various forms of energy into mechanical motion at the micro and nanoscale. These motors operate in environments characterized by low inertia and low Reynolds numbers. The potential applications of NMs are vast, particularly in the fields of biomedicine and environmental science. One of the most intriguing developments in this field is the integration of NMs with surface-enhanced Raman scattering (SERS) spectroscopy. SERS is a powerful analytical technique that enhances the Raman intensity of molecules, allowing for highly sensitive detection and analysis of trace amounts of substances. This integration offers highly precise and localized ultrasensing capabilities. The combination of NMs with SERS can also facilitate real-time imaging inside living organisms. This has immense potential in chemical and cell biology and medical diagnostics and prognosis. Herein this review describes the types of NMs and their fabrication, the incorporation of plasmonic nanostructures, capable of creating strong electromagnetic fields when illuminated by light, which in turn enhances the Raman signals significantly, their applications, and their future prospects in areas such as precision medicine, environmental monitoring, and possibly even in new realms like microscale robotics and targeted therapeutics.

纳米/微电机驱动的 SERS，用于高灵敏度和空间控制传感

纳米/微电机（NM）是一种微型结构，能够将各种形式的能量转化为微米和纳米尺度的机械运动。这些电机在低惯性和低雷诺数的环境中运行。 NM 的潜在应用非常广泛，特别是在生物医学和环境科学领域。该领域最有趣的发展之一是纳米材料与表面增强拉曼散射（SERS）光谱的集成。 SERS 是一种强大的分析技术，可以增强分子的拉曼强度，从而可以对痕量物质进行高灵敏度检测和分析。这种集成提供了高精度和本地化的超传感功能。 NM 与 SERS 的结合还可以促进生物体内的实时成像。这在化学和细胞生物学以及医学诊断和预后方面具有巨大的潜力。本文介绍了纳米材料的类型及其制造、等离子体纳米结构的结合（在光照射下能够产生强电磁场，进而显着增强拉曼信号）、它们的应用以及它们在精密等领域的未来前景医学、环境监测，甚至可能在微型机器人和靶向治疗等新领域。
