Magnetic levitation (MagLev) is a well-documented, robust technique for density measurements and separations. Although the potential of MagLev as an emerging tool in biotechnology has been recently investigated, the practical use of MagLev in diagnosis and disease detection merits further attention. This review highlights the diagnostic capacity of a simple and portable MagLev system and the possibilities and limitations of the MagLev technique for density-based separation, classification, and manipulation of soft matter and biological systems (e.g., cells, proteins), which in turn may pave the way for the discovery of disease-specific biomarkers.

磁悬浮 (MagLev) 是一种有据可查的稳健技术，用于密度测量和分离。尽管最近研究了 MagLev 作为生物技术新兴工具的潜力，但 MagLev 在诊断和疾病检测中的实际应用值得进一步关注。本综述重点介绍了简单便携 MagLev 系统的诊断能力，以及 MagLev 技术在软物质和生物系统（例如细胞、蛋白质）的基于密度的分离、分类和操作方面的可能性和局限性，这反过来可能为疾病特异性生物标志物的发现铺平道路。
