Cu nanoparticles are a potential material for creating novel alternative antimicrobial products due to their unique antibacterial/antifungal properties, stability, dispersion, low cost and abundance as well as being economical and ecofriendly. In this work, carboxymethyl cellulose coated core/shell SiO@Cu nanoparticles (NPs) were synthesized by a simple and effective chemical reduction process. The initial SiO NPs, which were prepared from rice husk ash, were coated by a copper ultrathin film using hydrazine and carboxymethyl cellulose (CMC) as reducing agent and stable agent, respectively. The core/shell SiO@Cu nanoparticles with an average size of ~19 nm were surrounded by CMC. The results indicated that the SiO@Cu@CMC suspension was a homogenous morphology with a spherical shape, regular dispersion and good stability. Furthermore, the multicomponent SiO@Cu@CMC NPs showed good antifungal activity against (). The novel Cu NPs-based multicomponent suspension is a key compound in the development of new fungicides for the control of the disease.
由于其独特的抗菌/抗真菌特性、稳定性、分散性、低成本、丰富性以及经济性和生态友好性，铜纳米颗粒是制造新型替代抗菌产品的潜在材料。在这项工作中，通过简单有效的化学还原过程合成了羧甲基纤维素包覆的核/壳SiO@Cu纳米颗粒（NPs）。最初由稻壳灰制备的SiO NPs，分别使用肼和羧甲基纤维素（CMC）作为还原剂和稳定剂，被铜超薄膜包覆。平均尺寸约为19 nm的核/壳SiO@Cu纳米颗粒被CMC包围。结果表明，SiO@Cu@CMC悬浮液具有均匀的形态，呈球形，分散规则且稳定性良好。此外，多组分SiO@Cu@CMC NPs对（）表现出良好的抗真菌活性。这种新型的基于铜纳米颗粒的多组分悬浮液是开发用于控制（）疾病的新型杀菌剂的关键化合物。
