There is a long-standing appreciation among environmental engineers and scientists regarding the importance of biologically derived colloidal particles and their environmental fate. This interest has been recently renewed in considering bacteriophages and extracellular vesicles, which are each poised to offer engineers unique insights into fundamental aspects of environmental microbiology and novel approaches for engineering applications, including advances in wastewater treatment and sustainable agricultural practices. Challenges persist due to our limited understanding of interactions between these nanoscale particles with unique surface properties and their local environments. This review considers these biological particles through the lens of colloid science with attention given to their environmental impact and surface properties. We discuss methods developed for the study of inert (nonbiological) particle-particle interactions and the potential to use these to advance our understanding of the environmental fate and transport of extracellular vesicles and bacteriophages.
在环境工程师和科学家中间，一直以来都高度重视生物衍生胶体颗粒及其环境归宿的重要性。在考虑噬菌体和细胞外囊泡时，这种兴趣最近又重新出现了，因为它们都有可能为工程师提供对环境微生物学基本方面的独特见解，并为工程应用提供新的方法，包括废水处理和可持续农业实践的进步。由于我们对这些具有独特表面性质的纳米级颗粒与局部环境之间的相互作用的了解有限，因此仍然存在挑战。本综述通过胶体科学的视角来考虑这些生物颗粒，重点关注它们的环境影响和表面性质。我们讨论了用于研究惰性（非生物）颗粒-颗粒相互作用的方法，以及利用这些方法来提高我们对细胞外囊泡和噬菌体的环境归宿和迁移的理解的潜力。
