Variety of bio-nanogold in the fabrication of lateral flow biosensors for detection of pathogenic bacteria.

Pathogenic bacteria constitute one of the most serious threats to human health. This has driven the development of technologies for the rapid detection of bacteria. Bio-nanogold-based lateral flow biosensors (LFBs) are a promising assay due to their low limit of detection, high sensitivity, good selectivity, robustness, low cost, and quick assay performance ability. The aim of this review is to provide a critical overview of the current variety of bio-nanogold LFBs and their targets, with a special focus on whole-cell and DNA detection of pathogenic bacteria. Challenges of bio-nanogold-based LFBs in improving their performance and accessibility are also comprehensively discussed.
