“…Microfluidic paper-based (μPADs) analytical devices provide an alternative platform for liquid transport via capillary forces without the need for external pumps [ 52 ] and they can be easily implemented for multiplexed analysis by simply adding channels [ 3 ]. Moreover, hydrophobic patterning can be employed to spatially confine the flow of hydrophilic solvent including biofluids [ 53 ].…”

Since the introduction of paper-based analytical devices as potential diagnostic platforms a few decades ago, huge efforts have been made in this field to develop systems suitable for meeting the requirements for the point-of-care (POC) approach. Considerable progress has been achieved in the adaptation of existing analysis methods to a paper-based format, especially considering the chemiluminescent (CL)-immunoassays-based techniques. The implementation of biospecific assays with CL detection and paper-based technology represents an ideal solution for the development of portable analytical devices for on-site applications, since the peculiarities of these features create a unique combination for fitting the POC purposes. Despite this, the scientific production is not paralleled by the diffusion of such devices into everyday life. This review aims to highlight the open issues that are responsible for this discrepancy and to find the aspects that require a focused and targeted research to make these methods really applicable in routine analysis.

“…In addition, bacterial cell damage during food processing can alter cellular metabolism and inhibit enzymatic activity; thus, detection following these procedures has a higher likelihood of false negatives or inadequate quantitative results. 135 Second, enzyme-based detection lacks high specificity due to the confounding production of target enzymes by nontarget strains. For example, while the enzyme–substrate pair β-galactosidase–CRPG is commonly used for the detection of E. coli O157:H7, many other nonpathogenic strains of E. coli have also been shown to produce varying amounts of β-galactosidase.…”

“…In another study, a μPAD with well-plate design was developed for the detection of Cronobacter spp. [37]. The detection is achieved based on the chromogenic reaction between enzymes (i.e., a-glucosidase) specifically produced by the pathogen and enzyme substrates (i.e., 5-bromo-4-chloro-3-indolyl-α-D-glucopyranoside), producing the aglycone 5-bromo-4-chloro-3-indole that shows indigo.…”

Food safety issues have recently attracted public concern. The deleterious effects of compromised food safety on health have rendered food safety analysis an approach of paramount importance. While conventional techniques such as high-performance liquid chromatography and mass spectrometry have traditionally been utilized for the detection of food contaminants, they are relatively expensive, time-consuming and labor intensive, impeding their use for point-of-care (POC) applications. In addition, accessibility of these tests is limited in developing countries where food-related illnesses are prevalent. There is, therefore, an urgent need to develop simple and robust diagnostic POC devices. POC devices, including paper- and chip-based devices, are typically rapid, cost-effective and user-friendly, offering a tremendous potential for rapid food safety analysis at POC settings. Herein, we discuss the most recent advances in the development of emerging POC devices for food safety analysis. We first provide an overview of common food safety issues and the existing techniques for detecting food contaminants such as foodborne pathogens, chemicals, allergens, and toxins. The importance of rapid food safety analysis along with the beneficial use of miniaturized POC devices are subsequently reviewed. Finally, the existing challenges and future perspectives of developing the miniaturized POC devices for food safety monitoring are briefly discussed.
