Abstract
Using magnetic nanobeads (MNBs) to extract nucleic acids is an efficient, inexpensive, easy automation, high throughput and good repeatability, instead of the traditional nucleic acid extraction (NAE) methods. Advances in fully automated MNBs-based nucleic acid extraction systems (MNAES) can push the frontiers of point-of-care testing (POCT) devices towards low-cost, automation, and enhanced accuracy molecular-level diagnostics. So, this paper introduces the pipettingbased MNAES with position of magnetic separation kit or tip, and based on magnetic bar MNAES with blending manner is shock or rotation. Further, advantages and disadvantages of various MNAES are compared. We envisage that the future trend in molecular diagnosis and monitoring will be facilitation, intelligent, miniaturization, and high throughput MNAES with sample-in-answer-out capability.
