Abstract
Cyclodextrins, with their unparalleled attributes of eco-friendliness, natural abundance, versatile utility, and facile functionalization, make a paramount contribution to the field of molecular imprinting. Leveraging the unique properties of cyclodextrins in molecularly imprinted polymers synthesis has revolutionized the performance of molecularly imprinted polymers, resulting in enhanced adsorption selectivity, capacity, and rapid extraction of pesticides, while also circumventing conventional limitations. As the concern for food quality and safety continues to grow, the need for standard analytical methods to detect pesticides in food and environmental samples has become paramount. Cyclodextrins, being non-toxic and biodegradable, present an attractive option for greener reagents in imprinting polymers that can also ensure environmental safety post-application. This review provides a comprehensive summary of the significance of cyclodextrins in molecular imprinting for pesticide detection in food and environmental samples. The recent advancements in the synthesis and application of molecularly imprinted polymers using cyclodextrins have been critically analyzed. Furthermore, the current limitations have been meticulously examined, and potential opportunities for greenification with cyclodextrin applications in this field have been discussed. By harnessing the advantages of cyclodextrins in molecular imprinting, it is possible to develop highly selective and efficient methods for detecting pesticides in food and environmental samples while also addressing the challenges of sustainability and environmental impact.

PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 299:122854. [PMID: 37196553 DOI: 10.1016/j.saa.2023.122854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 03/15/2023] [Accepted: 05/09/2023] [Indexed: 05/19/2023]
Abstract
The development of a ligand for their selective and sensitive detection is required due to the widespread use of Cu2+ in many industrial processes and the potential threat to human health. Herein, we report a bis-triazole linked organosilane (5) derived from the Cu(I) catalyzed azide-alkyne cycloaddition reaction. The synthesized compound 5 was characterized by (1H and 13C) NMR spectroscopic and mass spectrometry techniques. The UV-Visible and Fluorescence experiments of the designed compound 5 were performed with various metal ions, revealing its high selectivity and sensitivity to Cu2+ ions in MeOH: H2O (8:2, v/v, pH = 7.0, PBS buffer) solution. The selective fluorescence quenching upon addition of Cu2+ to the compound 5 is due to Photo-induced electron transfer process (PET). The limit of detection of compound 5 to Cu2+ was calculated as 2.56 × 10-6 M and 4.36 × 10-7 M through UV-Visible and Fluorescence titration data, respectively. The possible mechanism of 1:1 binding of 5 with Cu2+ could be affirmed by the density functional theory (DFT). Further, it was found that compound 5 showed a reversible behavior towards Cu2+ ions by the accumulation of sodium salt of CH3COO- which can be used in the construction of molecular logic gate where Cu2+ and CH3COO- are considered as inputs and the absorbance at 260 nm as output. Moreover, the molecular docking studies provide useful information about compound 5's interaction with the tyrosinase enzyme (PDB ID- 2Y9X).
