ABSTRACT

Patulin and Trichothecene as the main groups of mycotoxins in significant quantities can cause health risks from allergic reactions to death on both humans and animals. Accordingly, rapid and highly sensitive determination of these toxics agents is of great importance. This review starts with a comprehensive outlook regarding the characteristics, occurrence and toxic effects of Patulin and Trichothecene. In the following, numerous clinical and analytical approaches have been extensively discussed. The main emphasis of this review is placed on the utilization of novel nanomaterial based electrochemical sensing/biosensing tools for highly sensitive determination of Patulin and Trichothecene. Furthermore, a detailed and comprehensive comparison has been performed between clinical, analytical and sensing methods. Subsequently, the nanomaterial based electrochemical sensing platforms have been approved as reliable tools for on-site analysis of Patulin and Trichothecene in food processing and manufacturing industries. Different nanomaterials in improving the performance of detecting assays were investigated and have various benefits toward clinical and analytical methods. This paper would address the limitations in the current developments as well as the future challenges involved in the successful construction of sensing approaches with the functionalized nanomaterials and also allow exploring into core-research works regarding this area.[Formula: see text].

ABSTRACT

Fumonisins (FBs) can be found extensively in feedstuffs, foodstuffs, and crops. The consumption of the fumonisin-contaminated corn can result in esophageal cancer. In addition, the secondary metabolites of fungi termed mycotoxins may have some adverse effects on animals and humans such as estrogenicity, immunotoxicity, teratogenicity, mutagenicity, and carcinogenicity. Hence, developing sensitivity techniques for mycotoxins determination is of great importance. This paper reports the latest developments of nanomaterial-based electrochemical biosensing, apta-sensing, sensing, and immunosensing analyses to detect fumonisins. A concise study of the occurrence, legislations, toxicity, and distribution of FBs in levels monitoring was done. The techniques, different detection matrices, and approaches to highly selective and sensitive sensing methods were reviewed. The review also summarizes the salient features and the necessity of biosensing assessments in FBs detection, and diverse immobilization techniques. Furthermore, this review defined the performance of various electrochemical sensors using different detection elements couples with nanomaterials fabricated applying different detection elements coupled with nanomaterials (metal oxide nanoparticles (NPs), metal NPs, CNT, and graphene), the factors limiting progress, and the upcoming tasks in successful aptasensor fabrication with the functionalized nanomaterials.

ABSTRACT

Zearalenone (ZEN), a significant class of mycotoxin which is considered as a xenoestrogen, permits, similar to natural estrogens, it's binding to the receptors of estrogen resulting in various reproductive diseases especially, hormonal misbalance. ZEN has toxic effects on human and animal health as a result of its teratogenicity, carcinogenicity, mutagenicity, nephrotoxicity, genotoxicity, and immunotoxicity. To ensure water and environmental resources safety, precise, rapid, sensitive, and reliable analytical and conventional methods can be progressed for the determination of toxins such as ZEN. Different selective nanomaterial-based compounds are used in conjunction with different analytical detection approaches to achieve this goal. The current review demonstrates the state-of-the-art advances of nanomaterial-based electrochemical sensing assays including various sensing, apta-sensing and, immunosensing studies to the highly sensitive determination of various ZEN families. At first, a concise study of the occurrence, structure, toxicity, legislations, and distribution of ZEN in monitoring has been performed. Then, different conventional and clinical techniques and procedures to sensitive and selective sensing techniques have been reviewed and the efficient comparison of them has been thoroughly discussed. This study has also summarized the salient features and the requirements for applying various sensing and biosensing platforms and diverse immobilization techniques in ZEN detection. Finally, we have defined the performance of several electrochemical sensors applying diverse recognition elements couples with nanomaterials fabricated using various recognition elements coupled with nanomaterials (metal NPs, metal oxide nanoparticles (NPs), graphene, and CNT) the issues limiting development, and the forthcoming tasks in successful construction with the applied nanomaterials.

ABSTRACT

The need for food and agricultural resources is constantly rising, resulting in pesticide poisoning and environmental hazards. Diverse technologies collaborate to develop effective biosensors for detecting different pesticides, as it is difficult to achieve an efficient mechanism to detect pesticides. Novel solutions to reduce the cost and time for preparing samples in pesticide detection are being developed using new technologies. Moreover, methods like electrochemical techniques and fluorescence spectroscopy are now being improved to increase the sensitivity and make the operation more convenient. This article reviews the remarkable evolution in the structure of various Layered Double Hydroxides (LDHs), their various synthesis techniques, and their uses in various fields, especially in biological applications to detect pesticides in diverse contaminated samples. LDHs are layered materials with special characteristics favorable for pesticide detection. LDHs, have recently aroused increasing interest in research. We also discuss the latest advances made in the emergent strategies for improving the antimicrobial activity of LDHs.

ABSTRACT

Highly sensitive and rapid methods for the Ochratoxin A (OTA) detection as a main class of Ochratoxins (OT) in various food samples is significant. In the present review, novel OTA detection techniques based on electrochemical and conventional methods have been extensively explained, and also compared with each other in food samples. We classified the various electrochemical based techniques of OTA determination creatively into Impedimetric, Voltammetric, Amperometric and Electrochemiluminescence assays and their efficient comparison with conventional, and clinical methods including Capillary Electrophoresis (CE), High Performance Liquid Chromatography (HPLC), Liquid Chromatography/Mass Spectroscopy (LC/MS), and Enzyme Linked Immunosorbent Assay (ELISA) has been performed comprehensively. Moreover, structure, characteristics, and different types of OT and OTA are explained as extensively as possible. A summary of the current limitations and future challenges in OTA analysis are described, which efficiently provide a pathway for further developments and applications.
