Salmonella is one of the main causes of foodborne infectious diseases, posing a serious threat to public health. It can enter the food supply chain at various stages of production, processing, distribution, and marketing. High prevalence of Salmonella necessitates efficient and effective approaches for its identification, detection, and monitoring at an early stage. Because conventional methods based on plate counting and real‐time polymerase chain reaction are time‐consuming and laborious, novel rapid detection methods are urgently needed for in‐field and on‐line applications. Biosensors provide many advantages over conventional laboratory assays in terms of sensitivity, specificity, and accuracy, and show superiority in rapid response and potential portability. They are now recognized as promising alternative tools and one of the most on‐site applicable and end user–accessible methods for rapid detection. In recent years, we have witnessed a flourishing of studies in the development of robust and elaborate biosensors for detection of Salmonella in food. This review aims to provide a comprehensive overview on Salmonella biosensors by highlighting different signal‐transducing mechanisms (optical, electrochemical, piezoelectric, etc.) and critically analyzing its recent trends, particularly in combination with nanomaterials, microfluidics, portable instruments, and smartphones. Furthermore, current challenges are emphasized and future perspectives are discussed.

“…Silica NPs are one of the fluorescent alternatives to QDs and this is primarily due to their ability to be doped with large quantities of fluorescent dyes. They have seen a variety of applications within direct bacteriological detection, including E. coli , Salmonella , DPA detection, LFAs, and FC. ,, Other NP materials utilized in biothreat agent detection include polystyrene, fluorescent AuNPs, upconverting rare earth metal NPs, and micelles . As mentioned, MNPs are often used in the detection of bioagents, in conjugation with optical probes such as TiO 2 for the detection of Salmonella or fluorescently labeled antibodies for E. coli O157 …”

Although a fundamental understanding of the pathogenicity of most biothreat agents has been elucidated and available treatments have increased substantially over the past decades, they still represent a significant public health threat in this age of (bio)terrorism, indiscriminate warfare, pollution, climate change, unchecked population growth, and globalization. The key step to almost all prevention, protection, prophylaxis, post-exposure treatment, and mitigation of any bioagent is early detection. Here, we review available methods for detecting bioagents including pathogenic bacteria and viruses along with their toxins. An introduction placing this subject in the historical context of previous naturally occurring outbreaks and efforts to weaponize selected agents is first provided along with definitions and relevant considerations. An overview of the detection technologies that find use in this endeavor along with how they provide data or transduce signal within a sensing configuration follows. Current "gold" standards for biothreat detection/diagnostics along with a listing of relevant FDA approved in vitro diagnostic devices is then discussed to provide an overview of the current state of the art. Given the 2014 outbreak of Ebola virus in Western Africa and the recent 2016 spread of Zika virus in the Americas, discussion of what constitutes a public health emergency and how new in vitro diagnostic devices are authorized for emergency use in the U.S. are also included. The majority of the Review is then subdivided around the sensing of bacterial, viral, and toxin biothreats with each including an overview of the major agents in that class, a detailed cross-section of different sensing methods in development based on assay format or analytical technique, and some discussion of related microfluidic lab-on-a-chip/point-of-care devices. Finally, an outlook is given on how this field will develop from the perspective of the biosensing technology itself and the new emerging threats they may face.

The growing crisis of antibiotic resistance calls for advanced and sustainable antibacterial strategies. In the past few years, lanthanide‐doped upconversion nanoparticles (UCNPs) with unique photophysical properties have been innovatively explored for bacterial detection and therapy, and hold promise for alleviating challenges faced in the post‐antibiotic era. In this review, the interface engineering for the bacteria‐targeted UCNP nanoplatforms is highlighted, the principles and merits of various upconversion detection strategies are discussed, and the latest progress in UCNP‐based antibacterial applications are summarized, especially in deep‐tissue infection imaging and therapy. Finally, the remaining concerns and future efforts for practical applications are put forward. This review is expected to provide comprehensive guidance for diagnosing and combating bacterial infections based on advanced UCNP nanoplatforms.
