Molecular imprinting-based ratiometric fluorescence (MI-RFL) nanosensors receive increasing concerns in various fields such as food security, owing to high selectivity and sensitivity, nondestruction, convenience, visualization, etc. Herein, a ternary-emission MI-RFL nanosensor was facilely constructed by postimprinting mixing (PIM) red-emission molecularly imprinted polymers (r-MIPs) green MIPs (g-MIPs) for rapid visual detection of folic acid (FA) samples. The two fluorescent were prepared...
Antibiotics, as a representative of new pollutants, have always been challenge in the water treatment process, and most adsorption materials do not good capacity for them. Therefore, antibiotics was investigated using sulfadiazine (SDZ) antibiotics. In this paper, nickel successfully loaded onto surface chitosan through polyphenol metal network. TAB-Ni prepared by adding an appropriate amount tannic acid-chitosan material to 0.03 mol L-1 chloride under alkaline conditions, then calcined at...
Malachite green (MG) is a highly toxic dye commonly used in industries and aquaculture, leading to significant environmental contamination health hazards. Therefore, sensitive selective detection of MG real samples urgently needed. This study presents the development molecularly imprinted surface-enhanced Raman spectroscopy (MI-SERS) plasmonic sensor for rapid MG. The consists gold nanostar (Au NS) layer as SERS substrate an polydopamine containing specific recognition sites Taking full...
<p indent="0mm">Fluorescence sensors possess excellent advantages of high sensitivity, rapid response and simple operation. However, for single-emission fluorescence sensors, some uncontrollable factors, such as background signal, temperature, pH, can interfere with the detection results. In order to attain more sensitive accurate results, ratiometric come into being, self-correcting characteristics. Molecular imprinting technology (MIT) that mimics specific binding effect antigen antibody...
