The efficient and non-invasive collection of biological samples has become a critical challenge for the continued development of surface-enhanced Raman scattering (SERS). When integrated with minimally invasive microneedle (MN) sampling technology, SERS enhances its applicability in real-time, non-invasive molecular detection. This review focuses on the latest advances in MN-based SERS sensors. Firstly, a comprehensive summary is presented of MN types and research progress in the design and engineering of SERS-active MNs. Then, the sampling method of SERS MNs and the MN-based SERS detection mode are also described in detail. Finally, the applications of SERS MNs in fields such as disease diagnosis, drug monitoring, and food safety are highlighted. Additionally, current challenges are discussed and future development prospects are prospected with the aim of contributing to the design of MN-based SERS sensors for diverse applications.
生物样品的高效无创采集已成为表面增强拉曼散射(SERS)持续发展的一项关键挑战。当与微创微针(MN)采样技术相结合时,SERS增强了其在实时无创分子检测中的适用性。本综述聚焦于基于MN的SERS传感器的最新进展。首先,全面总结了MN的类型以及SERS活性MN设计与工程方面的研究进展。然后,还详细描述了SERS MN的采样方法以及基于MN的SERS检测模式。最后,突出了SERS MN在疾病诊断、药物监测和食品安全等领域的应用。此外,还讨论了当前面临的挑战并展望了未来的发展前景,旨在为设计用于各种应用的基于MN的SERS传感器提供帮助。
