Application of magnetic nanoparticles in nucleic acid detection

J Nanobiotechnology. 2020 Apr 21;18(1):62. doi: 10.1186/s12951-020-00613-6.

Abstract

Nucleic acid is the main material for storing, copying, and transmitting genetic information. Gene sequencing is of great significance in DNA damage research, gene therapy, mutation analysis, bacterial infection, drug development, and clinical diagnosis. Gene detection has a wide range of applications, such as environmental, biomedical, pharmaceutical, agriculture and forensic medicine to name a few. Compared with Sanger sequencing, high-throughput sequencing technology has the advantages of larger output, high resolution, and low cost which greatly promotes the application of sequencing technology in life science research. Magnetic nanoparticles, as an important part of nanomaterials, have been widely used in various applications because of their good dispersion, high surface area, low cost, easy separation in buffer systems and signal detection. Based on the above, the application of magnetic nanoparticles in nucleic acid detection was reviewed.

Keywords: Clinical diagnosis; High-throughput sequencing; Magnetic nanoparticles; Magnetic separation; Nucleic acid detection.
