- Abstract
- A conventional molecular assay-based point-of-care (POC) diagnostic test involves three major stages: deoxyribonucleic acid (DNA) extraction, amplification, and amplicon detection. Among these steps, DNA extraction is costly and time-consuming. Nevertheless, it is a crucial step for the identification of sensitive and specific diseases. This review summarizes the advantages and disadvantages of DNA extraction methods over the past 10 years to effectively implement POC pathogen testing in the future. The first section briefly explains the necessity of DNA extraction and molecular assays for food pathogen detection. The second section extensively discusses DNA extraction based on liquid-liquid extraction, solid-phase extraction, and electrophoretic techniques. Molecular assay-based methods and a few commercially available POC devices for the detection of foodborne pathogens are detailed in the third and fourth sections. Finally, present challenges and future perspectives for the fabrication of integrated POC devices are highlighted.
