Prospects for the application of aptamer based assay platforms in pathogen detection

Aptamer-based diagnostics platforms for animal, human, plant and environmental pathogens are gaining importance as they are rapid, user-friendly, sensitive and selective. However, most of the aptamer-based platforms have not yet become commercially available. The increasing number of publications signifies the applications of aptamer-based platform and their potential. Herein, the present review is to describe, a brief overview of the development of various aptamer-based platforms and their applicability for the sensitive detection of pathogens. In this review, several aptamer-based platforms such as Enzyme linked immunosorbent assay (ELISA)-like assay, Apta blot, Apta Polymerase Chain Reaction (PCR), Apta array, Aptamer-based Lateral Flow Assays (LFA), Aptamer based fluorescence assay, Flowcytometry-based assay, Apta affinity chromatography, microfluidics-based platforms, and various aptasensor have been discussed. Most of the platforms are highlighted will encourage researchers to focus on developing pathogen detection platform for various applications.
