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.
核酸是存储、复制和传递遗传信息的主要物质。基因测序在 DNA 损伤研究、基因治疗、突变分析、细菌感染、药物开发和临床诊断等方面具有重要意义。基因检测应用广泛,涉及环境、生物医学、制药、农业和法医学等领域。与 Sanger 测序相比,高通量测序技术具有输出量大、分辨率高、成本低等优点,极大地促进了测序技术在生命科学研究中的应用。磁性纳米粒子作为纳米材料的重要组成部分,由于其良好的分散性、高比表面积、低成本、在缓冲体系中易于分离和信号检测等优点,已被广泛应用于各种领域。基于以上这些,本文综述了磁性纳米粒子在核酸检测中的应用。
