Abstract

This study introduces a novel root protection method against Tobamovirus, using thermally responsive water-in-oil colloidosomes stabilized by halloysite nanotubes (HNTs). These colloidosomes are formed in situ through a cost-effective process using HNTs, canola oil, water, and two trietoxysilanes: (3-aminopropyl)trietoxysilanes (APTES) and Dodecyltriethoxysilane (DTES). The combination of hydrophilic APTES and hydrophobic DTES allows precise control over emulsion type and enables the formation of stable colloidosomes. A key feature of this system is the solar-triggered release of chlorinated trisodium phosphate (Cl-TSP), an antiviral agent that disinfects the root area and inactivates viral particles. The amount and timing of Cl-TSP release were measured, demonstrating controlled and localized delivery. The formulation provided high protection in tomato plants, while remaining biofriendly and environmentally safe. This work offers a smart-release platform for effective and sustainable crop protection.

刺激反应性高岭土胶体体在植物保护中抗病毒药物的主动递送

本研究介绍了一种利用高岭土纳米管（HNTs）稳定的热响应性油包水胶体体保护根抗托巴莫病毒的新方法。这些胶体体是通过使用HNTs、菜籽油、水和两种三乙基氧基硅烷（3-氨基丙基）三乙基氧基硅烷（APTES）和十二烷基三乙基氧基硅烷（DTES）的经济有效的工艺在原位形成的。亲水性APTES和疏水性DTES的结合可以精确控制乳液类型，并使形成稳定的胶体体。该系统的一个关键特点是太阳能触发的氯化磷酸三钠（Cl-TSP）的释放，这是一种抗病毒药物，可以消毒根部并灭活病毒颗粒。测定了Cl-TSP的释放量和释放时间，显示出控制和局部释放。该配方在番茄植株中提供了高保护，同时保持生物友好和环境安全。这项工作为有效和可持续的作物保护提供了一个智能释放平台。
