| 中文摘要 | 由於世界人口與糧食需求漸增，為提高與確保農作物之產量，開發新型永續抗植物病原微生物的材料相當重要。本研究中，利用水熱法並且控制合成環境中的酸鹼值來合成不同型態的奈米氧化鋅 (奈米棒 (1D)、奈米片 (2D) 與多枝花狀顆粒 (3D))，水熱法合成無需使用有機溶劑且為環境友善之合成方法，該些材料後續應用於對抑制土壤傳播植物病原菌的評估，這些土壤傳播病原菌為農業栽培上的限制因子；本研究成果顯示，多枝花狀氧化鋅 (3D) 具有較顯著和穩定的抗真菌特性，利用掃描式電子顯微鏡觀察結果發現多枝花狀氧化鋅可造成真菌的機械性損傷；此外，該些奈米材料具有光分解的特性與高度環境耐受性，具有減少化學農藥和環境友善的特性，本研究首次探討不同型態氧化鋅在抗菌的特性和農業中的應用能力，本研究發現多枝花狀氧化鋅可做為環境友善的抗菌材料。 |
| 英文摘要 | Owing to the exponential growth of the human population and the rising food demand, identifying sustainable antimicrobials for higher agricultural productivity becomes essential. In this study, hydrothermal precipitation for synthesizing versatile nanostructured zinc oxide particles (nZnOs), including nanorods (1D), nanoplatelets (2D), and multibranched flower-like particles (3D), was achieved by controlling pH values of source precursors and growth time. Hydrothermal synthesis is an eco-friendly process without the requirement of hazardous organic solvents. The antimicrobial properties of these nZnO particles were evaluated on different soil-borne plant pathogens. These pathogens are serious limiting factors in agriculture. Results indicate that multibranched flower-like ZnO (3D nZnO) showed more remarkable, reliable, and stable antifungal activity compared with other nZnOs. The scanning electron microscopy results also demonstrated significant mechanical damage to pathogens that caused by the branches of flower-like particles from 3D nZnO. Moreover, results of photodegradation and environmental resistance of the synthesized nZnOs revealed their potentials to reduce hazardous chemical pesticides and the eco-friendliness. This work is the first to compare the antimicrobial (i.e., antifungal) properties of various nZnOs and their applications in agriculture. Our results suggest that multibranched flower-like ZnO can be served as promising candidates of green antimicrobials with multiple modes of action in sustainable agriculture. |
