Herein,a novel interference-free surface-enhanced Raman spectroscopy(SERS)strategy based on magnetic nanoparticles(MNPs)and aptamer-driven assemblies was proposed for the ultrasensitive detection of histamine.A core-satellite SERS aptasensor was constructed by combining aptamer-decorated Fe_(3)O_(4)@Au MNPs(as the recognize probe for histamine)and complementary DNA-modified silver nanoparticles carrying 4-mercaptobenzonitrile(4-MBN)(Ag@4-MBN@Ag-c-DNA)as the SERS signal probe for the indirect detection of *** an applied magnetic field in the absence of histamine,the assembly gave an intense Raman signal at“Raman biological-silent”region due to *** the presence of histamine,the Ag@4-MBN@Ag-c-DNA SERS-tag was released from the Fe_(3)O_(4)@Au MNPs,thus decreasing the SERS *** optimal conditions,an ultra-low limit of detection of 0.65×10^(-3)ng/mL and a linear range 10^(-2)-10^5 ng/mL on the SERS aptasensor were *** histamine content in four food samples were analyzed using the SERS aptasensor,with the results consistent with those determined by high performance liquid *** present work highlights the merits of indirect strategies for the ultrasensitive and highly selective SERS detection of small biological molecules in complex matrices.

Investigation of conformational changes of cathepsin B as a feasibility assessment for NaCl reduction in Jinhua ham

引用

food Science and Human Wellness 2024年

作者： Shiqi Hu Guanghong Zhou Xinglian Xu Wangang Zhang Chunbao Li Key Laboratory of Meat processing and quality control Ministry of Education Key Laboratory of Meat processing Ministry of Agriculture and Rural Affairs Jiangsu Synergetic Innovation Center of Meat processing and quality control College of food Science and Technology Nanjing Agricultural University

To regulate the sodium chloride content in Jinhua ham， the impact of NaCl on the activity and conformation of cathepsin B was investigated using spectroscopy and computational methods. The results showed that the activity of cathepsin B decreased with an increase in Na+cation content and temperature. Additionally， decreased α-helix content and increased β-sheet content were observed. The increase in sulfhydryl group content was attributed to the breaking of original disulfide bonds in the molecular structure or the release of embedded groups. Furthermore， the surface hydrophobicity gradually declined， which was consistent with the analysis of endogenous fluorescence spectroscopy. At the molecular level， the number of hydrogen bonds formed in NaCl-treated samples decreased， and the interactions between the hydrogen bonding were less powerful， which caused instability in the binding of the protein and substrate. The conformation of cathepsin B accurately characterized its activity， and the structural changes had a macroscopic effect on the decrease in protease activity.

Covalent organic framework/carbon black/molecularly imprinted polydopamine composites for the selective recognition and electrochemical detection of ciprofloxacin

引用

food Science and Human Wellness 2024年

作者： Yufeng Sun Yongfeng Chen Xiaomin Pang Geoffrey I.N.Waterhouse Xuguang Qiao Zhixiang Xu Key Laboratory of food processing Technology and quality control in Shandong Province College of food Science and Engineering Shandong Agricultural University School of Chemical Sciences The University of Auckland

In this work， a novel electrochemical sensor based on covalent organic framework@carbon black@molecularly imprinted polydopamine （COF@CB@MPDA） was developed for selective recognition and determination of ciprofloxacin （CF）. COF@CB@MPDA possessed good water dispersibility and was synthesized by the self-polymerization of dopamine under alkaline conditions in the presence of the COF， CB and CF. The high surface area COF enhanced the adsorption of CF， whilst CB gave the composites high electrical conductivity to improve the sensitivity of the proposed COF@CB@MPDA/GCE sensor. The specific recognition of CF by COF@CB@MPDA involved hydrogen bonding and van der Waals interactions. Under optimized conditions， the sensor showed a good linear relationship with CF concentration over the range 5.0 × 10-7mol/L and 1.0 × 10-4mol/L， with a limit of detection （LOD） of 9.53 × 10-8mol/L. Further， the developed sensor exhibited high selectivity， repeatability and stability for CF detection in milk and milk powders. The method used to fabricate the COF@CB@MPDA/GCE sensor could be easily adapted for the selective recognition and detection of other antibacterial agents and organic pollutants in the environment.
