Aptamer–gold nanoparticle-based lab-in-a-tube colorimetric detection of malathion: evaluation with classical and digital readout techniques

Colorimetric biosensing devices represent an important class of point-of-care (POC) diagnostics due to their ability to provide visible test outputs, their ease of integration with smartphone-based sensing, and their portability for field testing. In the context of agrifood safety, there is a growing need for portable,...
