摘要循环胎儿细胞已被证实含有完整的细胞结构以及胎儿全套基因组信息，对循环胎儿细胞的分离与检测是无创产前诊断非整倍体疾病、染色体微缺失、单基因性疾病的重要策略之一。然而循环胎儿细胞的含量极低，对循环胎儿细胞的分离与检测仍具有一定的挑战。近年来，多种微流控技术、新型纳米材料等新型循环胎儿细胞分离、富集方法得到应用与发展。循环胎儿细胞的两大类新型分离、富集方法在文中得以总结，并对各类新型分离方法的原理、优缺点及分离效果进行比较。

abstractsCirculating fetal cells have been proven to contain complete cellular structures and comprehensive fetal genome information, enabling non-invasive prenatal diagnosis of aneuploidy diseases, chromosomal microdeletions, and monogenic diseases. However, due to the low abundance of these rare fetal cells in maternal peripheral blood, their isolation and detection remains challenging. In recent years, novel isolation and enrichment techniques, such as microfluidic technologies and novel nanomaterials, for circulating fetal cells enrichment have been continuously advancing.This review provides a comprehensive summary of two novel methodologies for the isolation and enrichment of circulating fetal cells. Their separation principles, advantages, limitations, as well as the separation efficiencies will also be described.
