“…To detect prostate-specific antigen, nitrocellulose membrane-based test strips were designed and measured by a portable NMR relaxometer [136]. Many other research groups attempted to adopt this technique to detect several biological components such as food borne bacteria [137][138][139][140] (See Figure 6).…”

The growing interest in magnetic materials as a universal tool has been shown by an increasing number of scientific publications regarding magnetic materials and its various applications. Substantial progress has been recently made on the synthesis of magnetic iron oxide particles in terms of size, chemical composition, and surface chemistry. In addition, surface layers of polymers, silica, biomolecules, etc., on magnetic particles, can be modified to obtain affinity to target molecules. The developed magnetic iron oxide particles have been significantly utilized for diagnostic applications, such as sample preparations and biosensing platforms, leading to the selectivity and sensitivity against target molecules and the ease of use in the sensing systems. For the process of sample preparations, the magnetic particles do assist in target isolation from biological environments, having non-specific molecules and undesired molecules. Moreover, the magnetic particles can be easily applied for various methods of biosensing devices, such as optical, electrochemical, and magnetic phenomena-based methods, and also any methods combined with microfluidic systems. Here we review the utilization of magnetic materials in the isolation/preconcentration of various molecules and cells, and their use in various techniques for diagnostic biosensors that may greatly contribute to future innovation in point-of-care and high-throughput automation systems.

Biofilm formation and extracellular microvesicles-The way of foodborne pathogens toward resistance Almost all known foodborne pathogens are able to form biofilms as one of the strategies for survival under harsh living conditions, to ward off the inhibition and the disinfection during food production, transport and storage, as well as during cleaning and sanitation of corresponding facilities. Biofilms are communities where microbial cells live under constant intracellular interaction and communication. Members of the biofilm community are embedded into extracellular matrix that contains polysaccharides, DNA, lipids, proteins, and small molecules that protect microorganisms and enable their intercellular communication under stress conditions. Membrane vesicles (MVs) are produced by both Gram positive and Gram negative bacteria. These lipid membrane-enveloped nanoparticles play an important role in biofilm genesis and in communication between different biofilm members. Furthermore, MVs are involved in other important steps of bacterial life like cell wall modeling, cellular division, and intercellular communication. They also carry toxins and virulence factors, as well as nucleic acids and different metabolites, and play a key role in host infections. After entering host cells, MVs can start many pathologic processes and cause serious harm and cell death. Prevention and inhibition of both biofilm formation and shedding of MVs by foodborne pathogens has a very important role in food production, storage, and food safety in general. Better knowledge of biofilm formation and maintaining, as well as the role of microbial vesicles in this process and in the process of host cells' infection is essential for food safety and prevention of both food spoilage and host infection.

“…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].…”

“…This sensor provided a LOD of 0.01 ng/mL with recovery values in the range of 92-110% and good consistency with ELISA results. MRS sensors in combination with m-NPs have also been employed for the analysis of food samples [82][83][84]. The sensor is based on the change in the spin-spin relaxation time produced on the surrounding water molecules as a result of the modifications on the dispersed and aggregate states of m-NPs when an analyte appears in the magnetic field.…”

“…These changes are measured through nuclear magnetic resonance (NMR). Among the applications in food analysis, the determination of bacterial populations is frequent [83,84], although organic individual compounds such as antibiotics (i.e., chloramphenicol, sulfonamide and oxytetracycline) have been also studied [82]. For example, Xianyu et al [82] developed a biosensor for analysing three antibiotics belonging to different families (amphenicols, sulphonamides and tetracyclines) in milk.…”

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.
