“…Since 2008, a series of studies have been reported involving aptamers specific for mycotoxins using electrochemical [ 40 ], colorimetric [ 41 ], and fluorescent transducers [ 42 ]. Among them, electrochemical aptasensors have gained interest recently due to their simplicity, affordability, sensitivity, and ease of miniaturization, which is widely useful in their on-site determination [ 43 ].…”

Mycotoxins are naturally occurring toxic secondary metabolites produced by fungi in cereals and foodstuffs during the stages of cultivation and storage. Electrochemical biosensing has emerged as a rapid, efficient, and economical approach for the detection and quantification of mycotoxins in different sample media. An electrochemical biosensor consists of two main units, a recognition receptor and a signal transducer. Natural or artificial antibodies, aptamers, molecularly imprinted polymers (MIP), peptides, and DNAzymes have been extensively employed as selective recognition receptors for the electrochemical biosensing of mycotoxins. This article affords a detailed discussion of the recent advances and future prospects of various types of recognition receptors exploited in the electrochemical biosensing of mycotoxins.

“…The authors constructed the metal-directed multiporphyrin array multilayers by spreading monolayers of tetrapyridylporphyrin (TPyP) linkers on the CdCl 2 subphase surfaces, where 2D/3D Cd-TPyP multilayers were constructed. This interfacial assembly technique has been often used to prepare ultrathin films, nanocrystals, and the supramolecular architecture of various multiporphyrin arrays and other CPs and MOFs. − The products as-prepared can be used for studying the molecular interactions, molecular arrangement, and distribution in the ultrathin films, for mimicking the photosynthetic reaction processes in nature and solar energy transfer, and for the development of fuel cells and molecular devices.…”

Metal-directed interfacial self-assembly of well-defined coordination polymer (CP) ultrathin films can control the metal complex arrangement and distribution at the molecular level, providing a convenient route for the design and fabrication of novel opto-electrical devices and heterogeneous catalysts. Here, we report the assembly of two series of CP multilayers with the transition-metal ions of Fe2+, Co2+, Zn2+ and Tb3+ as connectors and tripodal terpyridyl ligands of 4,4′,4″-(1,3,5-triazine-2,4,6-triyl)tris(1-(4-([2,2′:6′,2″-terpyridin]-4′-yl)benzyl)pyridin-1-ium) (TerPyTa) and 4,4′,4″-(benzene-1,3,5-triyl)tris(1-(4-([2,2′:6′,2″-terpyridin]-4′-yl)benzyl)pyridin-1-ium) (TerPyBen) as linkers at the air–water interface. The as-prepared Langmuir–Blodgett (LB) films display strong luminescence, with the emission wavelength and relative intensity dependent on both the metal ions and linkers; among them, the Zn-TerPyTa and Zn-TerPyBen CPs give off the strongest luminescent emission centered at about 370 nm with an emission lifetime of approximately 0.2–0.3 ns. The Tb-TerPyTa CPs can give off emission at approximately 490, 546, 586, and 622 nm, attributed to the 5D4 to 7F3–6 electron transitions of typical Tb3+ ions. Finally, these CP LB films can act as efficient heterogeneous photocatalysts for the CO2 reduction to selectively produce CO. The catalytic efficiency can be optimized by adjusting the experimental conditions (light sensitizer, electron donor, and water content) and CP composition (metal ion and ligand) with an excellent yield of up to 248.1 mmol g–1. In particular, it is revealed that, under the same conditions, the catalytic efficiency of the Fe-TerPyTa CP LB film is nearly 2 to 3 orders of magnitude higher than that of the other metalated complexes investigated in the homogeneous system. UV–vis spectroscopy and cyclic voltammetry studies demonstrated that the dual active sites of Fe-terpyridine and TerPyTa units contribute to the enhanced catalytic activity. This work provides an effective method to introduce the earth-abundant metal complexes into CP films to construct efficient noble-metal-free photocatalysts for the CO2 reduction.
