A dual-target aptamer functionalized probes (DTAFP) was applied for the detection of aflatoxin B1 (AFB1) and zearalenone (ZEN) simultaneously, which has not been reported. Meanwhile, two functional materials for signal amplification of the DTAFP were synthesized: 1) a three-dimensional molybdenum disulfide-reduced graphene oxide (MoS2-rGO) as a favorable loading interface; 2) a double-probes gold nanoparticles (AuNPs) modified by Thionin (Thi) and 6-(Ferrocenyl) hexanethiol (FC6S) as distinguishable and non-interfering signals. Mycotoxins on the electrode surface release into solution under the function of the DTAFP, leading a reduction of the differential peak impulse in signal response. Under the optimum conditions, the aptasensor exhibited a detection range of 1.0 pg mL−1–100 ng mL−1 for AFB1 and ZEN, with no observable cross reactivity. In addition, the aptasensor performed excellent stability, reproducibility, specificity, and favorable recovery in the detection of edible oil. This work demonstrated a novel method for the construction of a simple, rapid, and sensitive aptasensor in the detection of multiple mycotoxins simultaneously.

“…Furthermore, Yin and co-workers prepared an electrochemical sensor based on a MoS 2 −reduced graphene oxide (MoS 2 -RGO) composite for detecting Pb 2+ and Cd 2+ in edible mushrooms. 104 The obtained MoS 2 -RGO exhibited excellent detection capability with LODs of 0.13 μg/L and 0.59 μg/L for Pb 2+ and Cd 2+ , respectively. 28 Owing to the excellent photoresponse ability of MTG, the MTG was demonstrated to persistently produce ROS when exposed to simulated and showed markedly superior photocatalytic performance, approximately 15 times that of bare TiO 2 samples.…”

The pressure for agriculture security is a problem that affects human community at multiple levels, involving the production of agricultural commodities, the management of agricultural water and soil, and postharvest transport and storage. To date, agriculture security is increasingly becoming a challenge due to the abuse of chemicals, the indiscriminate discharge of wastewater, and the improper storage of agricultural products. As such, the determination and removal of hazardous contaminants in agricultural production chains are indispensable. As a fascinating semiconductor, molybdenum disulfide (MoS2), with controllable structure, appealing photoelectric properties, and superior physicochemical stability, is regarded as a promising material for the control of agricultural contaminants. This critical review summarizes the synthetic strategies for MoS2 and related efforts for agricultural contaminant control. It begins with the synthetic methods of the materials based on different principles. Subsequently, the determination and removal strategies based on MoS2 and its composites are discussed. The third part focuses on the description of MoS2-based platforms for control of different agricultural contaminants (heavy metals, pesticides, mycotoxins, antibiotics, and organic dyes). Finally, the challenges and potential opportunities for MoS2 application in modern agriculture are discussed.

“…In EC sensing, electrodes play the most significant part, which decides the efficiency of the sensor; different nanomaterials such as reduced graphene oxide (rGO), multiwalled carbon nanotubes (MWCNTs), Au nanoparticles, metal–organic frameworks (MOFs), metal oxides, SnS decorated with Bi 2 O 3 nanosheets, poly(glutamic acid) and carboxylated carbon nanosheets, N-doped-carbon nanosheets, Ru–GO nanocomposite, etc., have been extensively employed as promising modifiers of EC sensing electrodes for detecting Pb(II) and Cd(II) simultaneously. Recently, ultrathin two-dimensional (2D) nanomaterials such as graphene (Gr), Gr-based compounds, molybdenum disulfide (MoS 2 ), hexagonal boron nitride (h-BN), etc., have gained immense attention as electrode materials because of their properties such as possible higher specific surface area (SA), enhanced catalytic activity, structural flexibility, inertness, and biocompatibility. − …”

Pb(II) and Cd(II) are featured in the World Health Organization's (WHO) top 10 list of chemicals of primary public health concern, and their wide use in industries and the acute and chronic effects on humans and the environment make the detection and determination of the ions in environmental and drinking water samples indispensable. This work reports a detailed study on a partially reduced graphene oxide-nano molybdenum disulfide-modified glassy carbon electrode (prGO-MoS 2 /GCE), which exhibited the simultaneous and selective electrochemical detection of Pb(II) and Cd(II) in drinking water with a 200-and 100-fold increase in the current response, respectively, compared to that on the unmodified GCE. prGO-MoS 2 showed almost nil current response for other metal ions such as Hg(II), Ag(I), Fe(II), Co(II), Ni(II), Zn(II), Sn(II), Cu(II), and Cr(VI), evident to the good selectivity toward Pb(II) and Cd(II). The lowest limit of detection (LOD) values were ∼0.0002 and 0.1 ppt, which are very well below the ≤10 and 5 ppb specified as safe for Pb(II) and Cd(II), respectively. The exemplary sensing behavior of prGO-MoS 2 /GCE toward Pb(II) and Cd(II) shall be assigned to the structure of prGO-MoS 2 and the bonding of MoS 2 to prGO, thus promoting the electrochemistry mechanism in addition to the affinity.
