Abstract

Hybrid nanosystems based on nanoparticles of zero-valent copper (Cu⁰), zero-valent silver (Ag⁰), and zero-valent selenium (Se⁰) are synthesized. The nanoparticles are stabilized by a water-soluble random copolymer of 2-deoxy-2-methacrylamido-D-glucose with 2-dimethylaminoethyl methacrylate. A comparative study is made using UV–Vis spectroscopy and atomic force microscopy. The effect the nature of the nanoparticles has on the morphological and spectral characteristics of the formed nanosystems is shown. It is found that due to good screening, the reduction of nutrient ions in water in the presence of the indicated copolymer allows spherical nanostructures with diameters of 80 to 250 nm to be obtained.

摘要

合成了基于零价铜（Cu ⁰），零价银（Ag ⁰）和零价硒（Se ⁰）的纳米粒子的杂化纳米系统。纳米颗粒通过2-脱氧-2-甲基丙烯酰胺基-D-葡萄糖与甲基丙烯酸2-二甲基氨基乙基酯的水溶性无规共聚物来稳定。使用紫外可见光谱和原子力显微镜进行了比较研究。显示了纳米颗粒的性质对所形成的纳米系统的形态和光谱特性的影响。发现由于良好的筛选，在所示共聚物的存在下水中营养离子的还原使得能够获得直径为80至250nm的球形纳米结构。
