Book excerpt: Nanoparticles and Plant-Microbe Interactions: An Environmental Perspective, Volume Seven in the Nanomaterial-Plant Interactions series, provides comprehensive coverage on how nanoparticles can impact plant-microbe interactions. Key themes include nanoparticle synthesis, nano-phytoremediation, nano-farming, the negative impacts of nanoparticles, and nanomaterials in mitigating stress. This will be an essential read for any scientist or researcher looking to assess and understand the potential toxicological risks associated with plant nanotechnology, with particular focus on plant-microbe interactions. Nanotechnology is an emerging field with a vast range of nano-based products for commercial exploitation. The interactions of nanoparticles, plants and microbes can be harnessed in several applications, including alleviating environmental pollution. In addition to the aforementioned content, the book also explores concerns surrounding the toxicity of nanoparticles themselves, an important aspect to be aware, along with potential negative effects. Discusses the latest advances in the use of nanotechnology in plants and plant-microbe interactions Considers the potential negative impacts of nanotechnology on the environment Presents the applications of nanomaterials, including their role in stress mitigation
