Interactions between nanoparticles and bacteria (2017-2019)
Abstract
The intensive use of nanomaterials results in their continuous release into the environment. While there is convincing evidence showing various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. By investigating the responses of model organisms to nanoparticles at the cellular, enzymatic and gene expression levels, this project aims to develop a detailed understanding of how nanoparticles interfere with bacterial metabolism, and how such interactions would lead to cell death, lysis, and dispersal from biofilms. The findings will help to assess the immediate and long-term impact of nanoparticles on ecosystem health, for improved environmental management.
