Chirality induced spin selectivity (CISS) effect implies the relationship between chirality and magnetism, attracting extensive attention in the fields of physics, chemistry and biology. Since it was first discovered with photoemission method in 1999, the CISS effect has been investigated and measured by a variety of methods. Among different means of measurements, scanning probe microscopy (SPM) as a powerful tool to explore the CISS effect, can directly measure and present the spin filtering property of chiral molecules in electron transport. In this paper, we summarize the recent experiments on the CISS effect studied with scanning tunneling microscopy and atomic force microscopy, analyzing the experimental setups and results, and delving into the underlying mechanisms. The present review offers a concise introduction to several chiral molecules which are investigated by SPM for the CISS effect, and a detailed exploration of various experimental techniques tailored to the unique adsorption structures of these molecules. The impact of molecular structure on spin selectivity and the profound implications of CISS are also demonstrated together with a concise overview of CISS theory. A conclusive synopsis and forward-looking perspectives on the investigation of the CISS effect in electron transport utilizing SPM techniques are presented.
手性诱导自旋选择性（CISS）效应揭示了手性与磁性之间的关系，在物理、化学和生物学领域引起了广泛关注。自1999年首次通过光发射方法发现以来，人们已采用多种方法对CISS效应进行了研究和测量。在不同的测量手段中，扫描探针显微镜（SPM）作为探索CISS效应的有力工具，能够直接测量并呈现手性分子在电子输运中的自旋过滤特性。本文总结了最近利用扫描隧道显微镜和原子力显微镜对CISS效应开展的实验，分析了实验装置和结果，并深入探讨了其潜在机制。本综述简要介绍了几种通过SPM研究CISS效应的手性分子，并详细探讨了针对这些分子独特吸附结构的各种实验技术。同时还展示了分子结构对自旋选择性的影响以及CISS的深远意义，并简要概述了CISS理论。最后给出了利用SPM技术研究电子输运中CISS效应的总结性概要和前瞻性展望。
