Embodiment Construction
[0019] The beneficial effects of the present invention will be described in detail below in conjunction with the embodiments of the accompanying drawings, aiming at helping readers better understand the essence of the present invention, but not limiting the implementation and protection scope of the present invention.
[0020] First, rare earth coordination polymer nanoparticles were prepared under hydrothermal conditions, and the specific steps were as follows: Into a beaker containing 8 mL of N, N'-dimethylformamide, 2 mL of europium nitrate aqueous solution and 2 mL of isophthalic acid ethanol solution, stirred and reacted at room temperature for 30 minutes, then transferred the solution to the reaction kettle, and reacted at 170°C for 8 hours. After the reaction, the white product—that is, the rare earth coordination polymer was collected by centrifugation Nanoparticles, after fully washing with ethanol, the resulting precipitate was resuspended in ethanol for later use, ...

Abstract
A method for preparing rare earth coordination polymer nanoparticles and its application, dissolving europium nitrate and isophthalic acid in pure water and ethanol respectively, the concentration of the europium nitrate solution and isophthalic acid solution being 40 mM, The preparation method of the present invention is simple to operate and has low environmental requirements. As Hg 2+ The fluorescent probe has the advantages of simple and efficient, short reaction time, high sensitivity and good selectivity. At the same time, due to the good dispersion, uniform size and high fluorescence intensity of the prepared rare earth complex polymer nanoparticles, it is widely used in chemical transmission. It provides a new material in the fields of sensing, drug delivery and cell imaging, thus helping to expand the application of rare earth coordination polymers in the field of bioanalysis.
Description
technical field [0001] The invention relates to a method for preparing nanoparticles, in particular to a method for preparing rare earth coordination polymer nanoparticles and its application. Background technique [0002] Mercury is a highly toxic substance that easily accumulates in living organisms. Divalent mercury ion (Hg 2+ ) is one of the most stable inorganic mercury, which has a serious impact on human health and can seriously damage the brain, nervous system, kidney function and endocrine system of the human body. At present, mercury pollution as a global problem has attracted widespread attention. It is estimated that about 3,000 tons of mercury are released into the atmosphere through human activities every year in the world. Mercury is non-degradable. It cannot be decomposed in the environment, but can only be diluted or transformed. Therefore, the development of fast, simple and sensitive Hg 2+ Assay methods have always been chemistry and materials science ...
