“…Of the three broad biosensor detection methods described here (nucleic acid amplification, mass spectrometry and receptor‐ligand binding assays), all have been converted to portable platforms and tested for various applications. Examples include a portable, microfluidic PCR platform for detecting Escherichia coli (Salman, Carney, Bateson, & Ali, 2020); a field‐deployable miniaturized mass spectrometer for detection of illicit drug samples (Abonamah, Eckenrode, & Moini, 2019; see Figure 6b); and a microfluidic colorimetric immunoassay for smartphone‐based mycotoxin detection from food products (Man, Li, Li, Liu, & Pan, 2019).

Worldwide interest in the human microbiome is rapidly expanding, as the microbiome is a potential key to understanding human health and improving diagnostic and treatment strategies. A wide array of microorganisms, including bacteria, archaea, unicellular/multicellular eukaryotes (i.e. fungi and helminths) and viruses, colonize on the human body. Their activity and interactions with each other impact their host (Rowan-Nash, Korry, Mylonakis, & Belenky, 2019). Although sometimes used interchangeably, the word 'microbiota' refers to the collective community of microorganisms residing in a particular environment (such as a region of the body), whereas the word 'microbiome' refers to the entirety of this community's genetic information (Allaband et al., 2019; Kuczynski et al., 2012). The different regions of the human body contain various combinations of microbes that could provide information not only about infectious diseases at specific sites, but also about the potential health conditions of a person (Mimee et al., 2018). It is remarkable to consider that, according to recently revised estimates, the human body houses approximately as many bacteria (the most abundant member of the microbiota) as human cells, with bacteria comprising 0.3% of total body mass (Sender, Fuchs, & Milo, 2016).

Mycotoxins contamination is a global public health concern. Therefore, highly sensitive and selective techniques are needed for their on-site monitoring. Several approaches are conceivable for mycotoxins analysis, among which colorimetric methods are the most attractive for commercialization purposes thanks to their visual read-out, easy operation, cost-effectiveness, and rapid response. This review covers the latest achievements in the last five years for the development of colorimetric methods specific to mycotoxins analysis, with a particular emphasis on their potential for large-scale applications in food industries. Gathering all types of (bio)receptors, main colorimetric methods are critically discussed, including enzyme-linked assays, lateral flow-assays, microfluidic devices, and homogenous in-solution strategies. This special focus on colorimetry as a versatile transduction method for mycotoxins analysis is comprehensively reviewed for the first time.

“…Apart from the popular optical and electrochemical sensors, other interesting options based on m-NPs have been applied for food analysis. The main interest of these alternative sensors lies in the use of a different transduction principles (i.e., quartz crystal microbalance (QCM) [80,81], magnetic relaxation switching (MRS) [82][83][84], photoelectrochemistry [85,86]) or/and their particular arrangement (i.e., portable and low-cost sensors based on screen-printed electrode (ScPE) [73,85,[87][88][89][90][91][92], lateral flow strip (LFS) [93][94][95][96], microfluidic platforms [86,[97][98][99], and smartphone analysis [95,100,101]). Some selected examples of these kinds of devices are included in Table 6 [80,81,85,86,94,95,98,100,101].…”

“…Moreover, its combination with magnetic NPs allows benefiting from the advantages of these materials. Thus, it is not surprising that microfluidic chips using immunomagnetic separation [97,98], electrochemical, magnetic [99] or optical detection [98], have been developed. In these applications, the microfluidic chips were fabricated according to the particular needs and were mainly applied for the analysis of bacteria [97,99], although organic compounds (such as mycotoxins [98]) were also analysed.…”

Nanotechnology has become a topic of interest due to the outstanding advantages that the use of nanomaterials offers in many fields. Among them, magnetic nanoparticles (m-NPs) have been one of the most widely applied in recent years. In addition to the unique features of nanomaterials in general, which exclusively appear at nanoscale, these present magnetic or paramagnetic properties that result of great interest in many applications. In particular, in the area of food analysis the use of these nanomaterials has undergone a considerable increase since they can be easily separated from the matrix in sorbent-based extractions, providing a considerable simplification of the procedures. This allows reducing cost and giving fast responses, which is essential in the food trade to guarantee consumer safety. These materials can also be easily tunable, providing higher selectivity. Moreover, their particular electrical, thermal and optical characteristics allow enhancing sensor signals, increasing the sensitivity of the approaches based on this type of device. The aim of this review article is to summarise the most remarkable applications of m-NPs in food analysis in the last five years (2016–2020) showing a general view of the use of such materials in the field.
