Enhanced Electrochemical Sensing of Butylated Hydroxy Anisole through Hollow Metal–Organic Frameworks with Gold Nanoparticles and Enzymes

Wang Sun,
Huacong Chu,
Xiaoqian Zha
et al.

Abstract: Reliable methods for detecting butylated hydroxy anisole (BHA) in food and pharmaceutical products are crucial due to its potential toxicity. The utilization of hollow zeolite imidazolate framework-8 (ZIF-8) as host materials possessing both conducting and enzymatic properties presents a promising electrochemical sensing material. Herein, a facile synthesis strategy of ternary nanocomposite HRP@HZIF-Au was proposed, which involves the immobilization of horse radish peroxidase (HRP) into ZIF-8 through a copreci… Show more

“…19 One of their most common uses is in the analysis of different substances, including metal/non-metallic ions, food additives, and biological macromolecules. [20][21][22][23][24] The hydrothermal method is considered a more eco-friendly and cost-effective approach to preparing CDs. [25][26][27][28][29][30][31] CDs prepared from different natural sources have different emission wavelengths, which can be attributed to the chemical components present in the sources that determine the allocation of surface functional groups of CDs.…”

“…Colorimetric detections are convenient and effective in many applications because the readout requires only human eyes, without the aid of any sophisticated instruments. In the last few decades, plasmonic nanoparticles, especially Au nanoparticles (AuNPs), have attracted much attention as an ideal transducer of colorimetry for sensing, recognizing, and determination of ions and small biomolecules, 20–24 because the aggregation of solutions with low concentrations of AuNPs displays a clear color change. The detection of OCl − can also use AuNP-based colorimetric methods.…”
