“…The methods based on biosensors would be applied as an appropriate alternative due to their accessibility, simplicity, and quick recognition (Sohrabi, Javanbakht, et al., 2021; Sohrabi, Majidi, Arbabzadeh, et al., 2021; Sohrabi et al., 2022; Sohrabi, Majidi, Nami, et al., 2021). In the past 25 years, biosensors (Sohrabi, Majidi, Asadpour‐Zeynali, Khataee, Dastborhan, et al., 2022) have been developed for detecting pathogens, which have been established on the direct integration of a sensitive transducer and a selective biorecognition element and have provided complementary platforms for PCR and ELISA to quantify and identify pathogens. Furthermore, a biosensor provides quantitative or semiquantitative analytical measurement and data without requiring further reagents or processing stages (Cesewski & Johnson, 2020; Sohrabi, Hemmati, et al., 2021).…”

Diverse chemicals and some physical phenomena recently introduced in nanotechnology have enabled scientists to develop useful devices in the field of food sciences. Concerning such developments, detecting foodborne pathogenic bacteria is now an important issue. These kinds of bacteria species have demonstrated severe health effects after consuming foods and high mortality related to acute cases. The most leading path of intoxication and infection has been through food matrices. Hence, quick recognition of foodborne bacteria agents at low concentrations has been required in current diagnostics. Lateral flow assays (LFAs) are one of the urgent and prevalently applied quick recognition methods that have been settled for recognizing diverse types of analytes. Thus, the present review has stressed on latest developments in LFAs‐based platforms to detect various foodborne pathogenic bacteria such as Salmonella, Listeria, Escherichia coli, Brucella, Shigella, Staphylococcus aureus, Clostridium botulinum, and Vibrio cholera. Proper prominence has been given on exactly how the labels, detection elements, or procedures have affected recent developments in the evaluation of diverse bacteria using LFAs. Additionally, the modifications in assays specificity and sensitivity consistent with applied food processing techniques have been discussed. Finally, a conclusion has been drawn for highlighting the main challenges confronted through this method and offered a view and insight of thoughts for its further development in the future.

“…Fe-Ti was used for the removal of fluoride from drinking water [50]. Fe-Mn and Co-Fe have also been used as antifouling agent to prevent corrosion or reduce the growth or speedup the detachment of the subaquatic organism that usually stick at the bottom or hull of a vessel and also affect its performance [273][274][275].…”

“…Bimetallic nanoparticles have been used in the fabrication of nanosensors, nanochips, nano semiconductors and nanocoating. For example, Ag-Cu, Au-Cu, Fe-Mn, Pd-Ru, Ag-Cu, Co-Ni, Au-Ag, Au-Pt, Cu-Sn and Pd-Au bimetallic nanoparticles have been used to fabricate sensors/biosensors that can sense dimethoate [34], hydrazine [30] and detect Salmonella typhimurium in milk samples [275], as well as an anti-cancer drug [276], anti-inflammatory drug 4-aminoantipyrine [277], luteolin [278], favipiravir [279], diclofenac [280], glucose in serum [281] and coal mine gases sensor [131]. For detecting pesticide contaminants in the environment, many bimetallic nanoparticles have been used including Ag-Au, Au-Pd, Au-Pt, Au-Ag for detecting organophosphorus pesticides, carbamates nerve agents, and pesticides of leachate in contaminated groundwater [282][283][284][285].…”

The manipulation of matter at the atomic level (nanotechnology) has experienced an explosion in research interest in recent years. Bimetallic nanoparticles are vital due to their high biocompatibility, stability and comparatively less toxicity. The synthesis methods that include physical, chemical and biological methods are explored and explained in detail, along with their advantages. They have a wide range of applications due to their synergistic properties including biological applications (in medicine and agriculture), environmental application (in water treatment and removal of toxic contaminants), engineering application (in nanosensors, nanochips and nano-semiconductors) and chemical and physical application (in optics, catalysis and paints). The green synthesis approach is a promising method of synthesis that can give rise to more biocompatible and less toxic bimetallic nanoparticles due to increasing environmental pollution. However, despite these interesting attributes of bimetallic nanoparticle, there is still much work to be done to improve the biocompatibility of bimetallic nanoparticles because of their toxicity and potentially hazardous effects.

“…The biosensor term refers to an analytical tool with the ability to diagnose biological analytes, including microbial pathogens (virus, bacteria, etc.) [ 74 ], nucleic acids (RNA and DNA) [ 75 , 76 ], cancer biomarkers [ 77 ], enzymes, whole cells [ 78 ], cell receptors, etc., directly or indirectly [ 79 ]. The bio-receptor (biological recognition element), signal transducer, and amplifier are the three parts of a biosensor, of which interaction with bio-receptor and transducer produces a detectable signal ( Figure 1 ).…”

Gastroenteritis, as one of the main worldwide health challenges, especially in children, leads to 3–6 million deaths annually and causes nearly 20% of the total deaths of children aged ˂5 years, of which ~1.5 million gastroenteritis deaths occur in developing nations. Viruses are the main causative agent (~70%) of gastroenteritis episodes and their specific and early diagnosis via laboratory assays is very helpful for having successful antiviral therapy and reduction in infection burden. Regarding this importance, the present literature is the first review of updated improvements in the employing of different types of biosensors such as electrochemical, optical, and piezoelectric for sensitive, simple, cheap, rapid, and specific diagnosis of human gastroenteritis viruses. The Introduction section is a general discussion about the importance of viral gastroenteritis, types of viruses that cause gastroenteritis, and reasons for the combination of conventional diagnostic tests with biosensors for fast detection of viruses associated with gastroenteritis. Following the current laboratory detection tests for human gastroenteritis viruses and their limitations (with subsections: Electron Microscope (EM), Cell Culture, Immunoassay, and Molecular Techniques), structural features and significant aspects of various biosensing methods are discussed in the Biosensor section. In the next sections, basic information on viruses causing gastroenteritis and recent developments for fabrication and testing of different biosensors for each virus detection are covered, and the prospect of future developments in designing different biosensing platforms for gastroenteritis virus detection is discussed in the Conclusion and Future Directions section as well.
