Silver nanoparticles (AgNPs) are widely used as engineered nanomaterials (ENMs) in many advanced nanotechnologies, due to their versatile, easy and cheap preparations combined with peculiar chemical-physical properties. Their increased production and integration in environmental applications including water treatment raise concerns for their impact on humans and the environment. An eco-design strategy that makes it possible to combine the best material performances with no risk for the natural ecosystems and living beings has been recently proposed. This review envisages potential hybrid solutions of AgNPs for water pollution monitoring and remediation to satisfy their successful, environmentally safe (ecosafe) application. Being extremely efficient in pollutants sensing and degradation, their ecosafe application can be achieved in combination with polymeric-based materials, especially with cellulose, by following an eco-design approach. In fact, (AgNPs)-cellulose hybrids have the double advantage of being easily produced using recycled material, with low costs and possible reuse, and of being ecosafe, if properly designed. An updated view of the use and prospects of these advanced hybrids AgNP-based materials is provided, which will surely speed their environmental application with consequent significant economic and environmental impact.
由于银纳米颗粒（AgNPs）具有多种特性、制备简便且成本低廉，同时具备独特的化学物理性质，因此在许多先进纳米技术中被广泛用作工程纳米材料（ENMs）。它们在包括水处理在内的环境应用中的产量增加和整合，引发了人们对其对人类和环境影响的担忧。最近提出了一种生态设计策略，该策略能够将最佳的材料性能与对自然生态系统和生物无风险相结合。本综述设想了用于水污染监测和修复的AgNPs潜在混合解决方案，以实现其成功且环境安全（生态安全）的应用。通过遵循生态设计方法，AgNPs在污染物传感和降解方面极其高效，其生态安全应用可与基于聚合物的材料，特别是纤维素相结合来实现。事实上，（AgNPs）-纤维素杂化物具有双重优势，即使用回收材料易于生产，成本低且可重复使用，并且如果设计得当则具有生态安全性。本文提供了这些先进的基于AgNP的杂化材料的使用和前景的最新观点，这必将加速它们在环境中的应用，从而产生重大的经济和环境影响。
