Recent advances and trends in magnetic nanoparticle-assisted aptasensors for foodborne bacteria monitoring: applications, challenges, and updates.

ABSTRACT: Foodborne illnesses are a serious threat to public health. This study reviews recent advances in magnetic nanoparticle-based aptasensors for monitoring foodborne bacteria, focusing on their applications, challenges, and future prospects. We analyze the latest developments in magnetic nanoparticle-based aptasensors in optical (colorimetric, fluorescence, surface-enhanced Raman scattering), electrochemical, and other sensors for the detection of foodborne bacteria. We review the application of magnetic nanoparticles (MNPs) in biosensor structures for various purposes, including signal generation and processing, purification, immobilization of target biomarkers, and bacterial isolation. Various challenges are discussed, such as increasing the affinity of aptamers, commercialization barriers,
