Interactions between nanoparticles and bacteria

点击翻译按钮获取中文摘要

This project aims to understand how nanoparticles interfere with bacterial metabolism, and how these interactions lead to cell death, lysis and dispersal from biofilms. Intensive use of nanomaterials results in their continuously releases into the environment. While various nanoparticles have inhibitory and even toxic effects on microorganisms in ecosystems, the underlying mechanisms are not understood. This project will investigate model organisms’ responses to nanoparticles at the cellular, enzymatic and gene expression levels. The findings are expected to help assess the immediate and long-term effect of nanoparticles on ecosystem health, for improved environmental management.
