几个世纪以来，铜杀菌剂已广泛用于农业，导致植物病原体产生抗药性和其他环境问题。以前，与标准铜产品相比，铜-二氧化硅纳米颗粒（Cu-Si NPs）已经表现出增强的抗微生物性能。纤维素是最丰富的生物聚合物，它具有生物可降解性，并且其许多纳米材料具有抗菌性能，导致研究新型纤维素-Cu-Si纳米复合材料以提高Cu-Si NPs的功效。针对苜蓿黄单胞菌（铜敏感性病原体）和穿孔黄单胞菌GEV-485（铜耐受性病原体）评估这些材料。结果表明，该复合材料有可能减少铜在农业工业中的使用。
Copper biocides have been widely used in agriculture for centuries, causing plant pathogens to develop resistance and other environmental problems. Previously, copper-silica nanoparticles (Cu-Si NPs) have demonstrated enhanced antimicrobial properties compared to standard copper products. Cellulose is the most abundant biopolymer, it possesses biodegradability, and many of its nanomaterials exhibit antimicrobial properties, leading to the study of novel cellulose-Cu-Si nanocomposites to improve the efficacy of Cu-Si NPs. These materials were assessed against Xanthomonas alfalfae (copper-sensitive pathogen) and Xanthomonas perforans GEV-485 (copper-tolerant pathogen). Results suggest that the composite has potential to minimize copper use in agriculture industry.
