Abstract

Abstract Magnetic levitation (MagLev) is a density-based method which uses magnets and a paramagnetic medium to suspend multiple objects simultaneously as a result of an equilibrium between gravitational, buoyancy, and magnetic forces acting on the particle. Early MagLev setups were bulky with a need for optical or fluorescence microscopes for imaging, confining portability, and accessibility. Here, we review design criteria and the most recent end-applications of portable smartphone-based and self-contained MagLev setups for density-based sorting and analysis of microparticles. Additionally, we review the most recent end applications of those setups, including disease diagnosis, cell sorting and characterization, protein detection, and point-of-care testing.

便携式磁悬浮技术

摘要磁悬浮（MagLev）是一种基于密度的方法，它使用磁铁和顺磁性介质，由于作用在粒子上的重力、浮力和磁力之间的平衡，同时悬浮多个物体。早期的MagLev设备体积庞大，需要光学或荧光显微镜进行成像，限制了便携性和可访问性。在这里，我们回顾了基于便携式智能手机和独立的MagLev设置的设计标准和最新的最终应用，用于基于密度的微粒分选和分析。此外，我们还回顾了这些装置的最新最终应用，包括疾病诊断、细胞分选和表征、蛋白质检测和护理点测试。
