“…As in this case, using labels for monitoring the immunoaffinity event is the most common: the enzyme horseradish peroxidase is widely used. However, the use of nanomaterials such as gold nanoparticles (AuNP) [ 69 , 75 , 76 ] and CdS nanocrystals [ 68 ] is also frequent. A remarkable label is the one based on a polymeric dendron modified with CdTe Quantum Dots (QD) which was recently developed by Murasova et al [ 77 ].…”

“…Another approach to develop sensors able to perform simultaneous measurements is the use of SPEs with more than one WE or more than one electrochemical cell. Examples of these sensors for Salmonella detection are also reported: from SPEs with two WEs [ 79 ], to a microfluidic system with eight WEs [ 75 ] ( Figure 4 C) or a 96-well-SPE plate [ 80 ].…”

Food spoilage is caused by the development of microorganisms, biogenic amines, and other harmful substances, which, when consumed, can lead to different health problems. Foodborne diseases can be avoided by assessing the safety and freshness of food along the production and supply chains. The routine methods for food analysis usually involve long analysis times and complex instrumentation and are performed in centralized laboratories. In this context, sensors based on screen-printed electrodes (SPEs) have gained increasing importance because of their advantageous characteristics, such as ease of use and portability, which allow fast analysis in point-of-need scenarios. This review provides a comprehensive overview of SPE-based sensors for the evaluation of food safety and freshness, focusing on the determination of bacteria and biogenic amines. After discussing the characteristics of SPEs as transducers, the main bacteria, and biogenic amines responsible for important and common foodborne diseases are described. Then, SPE-based sensors for the analysis of these bacteria and biogenic amines in food samples are discussed, comparing several parameters, such as limit of detection, analysis time, and sample type.

“…During the years 2018-19, nine new methods using FIA-SPE systems were developed for the determination of analytes such as isoniazid, [60] arsenic, [61] salmonella bacteria, [62] o-diphenol and its derivatives, [63] ethoxyquin, [64] glucose, [65] naproxen, [66] three tumor biomarkers, [67] acetaminophen, [68] and tryptophan and pyridoxine simultaneously. [69] Oliveira et al [62] reported a simple, low-cost, and fully disposable microfluidic FIA device for ultrasensitive Salmonella bacteria detection. The bacteria were magnetically-captured and separated from milk samples using magnetic beads modified with a monoclonal anti-Salmonella antibody, followed by the addition of polyclonal anti-Salmonella antibody labeled with AuNPs.…”

This review addresses the use of screen-printed electrodes (SPEs) coupled to flow systems such as flow injection analysis (FIA), batch injection analysis (BIA), and high-performance liquid chromatography (HPLC) systems over the last six years (since 2014). The combination of SPEs and flow systems is a powerful synergy to increase the throughput of measurements, improve electrode lifetime, and reduce reagent consumption and waste generation. Recently, commercial flow cells for SPEs were made available by different companies and potential new users that are unable to construct homemade electrochemical flow cells have been attracted to work in the area. This overview aims to show both trends and future potential for the development of new methods useful for modern electroanalysis and/or portable applications.

“…On the other hand, surface modification and conjugation of different shape of inorganic metals had received some attention. Sandwich assay complex involving the aggregation of specific monoclonal and polyclonal antibodies on the surface of magnetic nanobeads and AuNPs respectively detect Listeria monocytogenes and S. typhi cells [104,105]. Wu et al [106] examined the effect of aptamer-modified magnetic microparticles linked with antibody-coated gold nanoparticles.…”

Infections acquired from ingesting contaminated food and water poses an adverse effect on public health and safety, thus affecting nations' economy. Technical approaches developed over years have contributed adequately to microbial detection in food and water, yet, unveiling spaces for more improvement on early and rapid detection of pathogens. This review highlights different strategy assessing bio-functionalized inorganic nanoparticles towards the detection of pathogens in food and water samples. Conjugates of several bio-receptors and inorganic nanoparticles showed rapid, real-time, repeatability, and appreciable limit of detection in targeted pathogens. A patent referenced in this study established the biocompatibility of bio-functionalized inorganic nanoparticles mechanism. Unique attributes exhibited by bio-functionalized inorganic nanoparticles showed potential and improvement of the existing bio-sensing pathogen detection methods. Each of the identified strategies described showed a promising pathway accommodating the development of simple, and even the fabrication of low-cost materials for easy detection of bacterial pathogens in food and water products.
