Abstract Foodborne pathogens are a crucial diagnostic target for the food, beverage, and healthcare sectors due to their ubiquity potential damage they may do public's well‐being, food safety, economy. Over past few decades, there has been an increased focus on developing highly precise trusted biosensors in effort eliminate discrepancy between reporting demands currently used traditional detection approaches. Metal oxide semiconductor (MOS)‐based gas sensors have rapidly advanced recent years, becoming dominating technology devices food‐quality management, biomedical research, diagnostics. This review systematically explores advancements sensing technologies utilizing metal oxide‐based of foodborne through analysis volatile organic compounds (VOCs). The comprehensive discussion encompasses insights into various pathogens, implications human health, diverse characteristics, strategies enhancing capabilities, distinctive features VOCs. Furthermore, thorough examination utilization different oxides VOC is provided, addressing both existing challenges future developments. In summary, employing techniques pathogen holds substantial commercial promise compared alternative bio‐sensing

This work presents a novel nanostructured material SnO2/multiwalled carbon nanotubes (MWCNTs) as sensing film for the detection of acetone and ethanol vapors. The fabrication SnO2/MWCNT chemoresistive sensors demonstrates cost-effective hydrothermal method using centrifugation technique. investigation synthesized SnO2/MWCNTs nanocomposite represents various techniques, such scanning electron microscopy (SEM), transmission (TEM), energy-dispersive X-ray (EDX) elementary analysis, EDX mapping, diffraction (XRD) analysis. sensor exhibits rapid response/recovery behavior toward (53/5 s) (86/3 while showing satisfactory values responsiveness (Sact = 90.5 Setn 21, n 100 ppm). low limit these vapors is assigned concentration 1 ppm, where discernible responses are elicited. Thus, production efforts have yielded high-end volatile organic compound (VOC) detector, highly suitable human technological engineering activity.
