“…In light of this, Li et al. employed Mg/Zn‐MOF‐74@Fe 3 O 4 magnetic nanocomposites‐based pretreatment for AFB 1 detection in grain samples (Li, Wei et al., 2022). The synthesized Mg/Zn‐MOF‐74@Fe 3 O 4 MNPs have a theoretical adsorption capacity of 8.92 mg/g attributed to their good dispersity and the abundant adsorption sites for analytes.…”

“…A novel current variation‐based electrochemical biosensing for mycotoxin has been reported by Chen's group (Li, Wei et al., 2022), which integrated MNPs and PS beads for constructing a microchannel resistance sensor (MCRS). In this type of sensor, the biometric molecules (antigens or Abs) were individually immobilized on MNPs and PS microspheres, and their immune reaction led to a measurable alteration in the quantity of unbound PS microspheres.…”

“…Fe 3 O 4 @PDA‐Ab effectively bridged the sample pretreatment and signal readout, hence the whole detection process can be achieved within 1 h. Herein, the formation of Fe 3 O 4 @PDA‐Ab/PS@BSA‐DON immunocomplexes led to a significant variation in the current signal, attributed to the blocking effect, upon their introduction into the microchannel (Figure 6c) (Peng et al., 2023). Further, the integration of MSPE before MCRS biosensing contributed a minimized impurity interferences and signal amplification (Li, Wei et al., 2022).…”

Mycotoxin contamination of food crops is a global challenge due to their unpredictable occurrence and severe adverse health effects on humans. Therefore, it is of great importance to develop effective tools to prevent the accumulation of mycotoxins through the food chain. The use of magnetic nanoparticle (MNP)‐assisted biosensors for detecting mycotoxin in complex foodstuffs has garnered great interest due to the significantly enhanced sensitivity and accuracy. Within such a context, this review includes the fundamentals and recent advances (2020–2023) in the area of mycotoxin monitoring in food matrices using MNP‐based aptasensors and immunosensors. In this review, we start by providing a comprehensive introduction to the design of immunosensors (natural antibody or nanobody, random or site‐oriented immobilization) and aptasensors (techniques for aptamer selection, characterization, and truncation). Meanwhile, special attention is paid to the multifunctionalities of MNPs (recoverable adsorbent, versatile carrier, and signal indicator) in preparing mycotoxin‐specific biosensors. Further, the contribution of MNPs to the multiplexing determination of various mycotoxins is summarized. Finally, challenges and future perspectives for the practical applications of MNP‐assisted biosensors are also discussed. The progress and updates of MNP‐based biosensors shown in this review are expected to offer readers valuable insights about the design of MNP‐based tools for the effective detection of mycotoxins in practical applications.
