Functionalized Ferroferric Oxide Nanomagnetic Beads for Extraction of Nucleic Acid and Its Application in Early Screening of Colorectal Cancer. JOURNAL OF HEALTHCARE ENGINEERING 2021; 2021:5230666. [PMID: 34900193 PMCID: PMC8654521 DOI: 10.1155/2021/5230666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 08/31/2021] [Accepted: 10/11/2021] [Indexed: 11/17/2022]
Abstract
Early screening is an important way to reduce the incidence and mortality of colorectal cancer (CRC). Fecal DNA testing stands out among many screening methods due to its high sensitivity. However, at this stage, researchers have not found a high-efficiency method for fecal DNA extraction. To this end, this work carried out a new round of exploration. Here, this experiment synthesized a kind of nanomagnetic beads (NH2-SiO2@Fe3O4) with good stability for nucleic acid extraction. A comparative study with the centrifugal adsorption column method revealed the significant advantages of the magnetic bead method in extracting fecal DNA. The DNA extracted by the magnetic bead method is of high purity, can also achieve high-throughput tests, and is more suitable for polymerase chain reaction detection, greatly simplifying the stool DNA detection process and providing a basis for the widespread promotion of early screening.

Abstract
Nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are natural biopolymers composed of nucleotides that store, transmit, and express genetic information. Overexpressed or underexpressed as well as mutated nucleic acids have been implicated in many diseases. Therefore, nucleic acid tests (NATs) are extremely important. Inspired by intracellular DNA replication and RNA transcription, in vitro NATs have been extensively developed to improve the detection specificity, sensitivity, and simplicity. The principles of NATs can be in general classified into three categories: nucleic acid hybridization, thermal-cycle or isothermal amplification, and signal amplification. Driven by pressing needs in clinical diagnosis and prevention of infectious diseases, NATs have evolved to be a rapidly advancing field. During the past ten years, an explosive increase of research interest in both basic research and clinical translation has been witnessed. In this review, we aim to provide comprehensive coverage of the progress to analyze nucleic acids, use nucleic acids as recognition probes, construct detection devices based on nucleic acids, and utilize nucleic acids in clinical diagnosis and other important fields. We also discuss the new frontiers in the field and the challenges to be addressed.
