Exploiting bacterial metal resistance machinery for metal ion nano-biosensors development

点击翻译按钮获取中文摘要

This project aims to integrate advanced materials chemistry, molecular biology, bio-electrochemical and synchrotron imaging approaches to understand the role of silver resistance machinery of bacteria in their ability to form silver nanoparticles. This aims to enable discovery of new metal-specific reductase enzymes. The fundamental biomolecular understanding of bacterial silver resistance will allow the use of a silver-binding protein to develop a series of next-generation nano-biosensors. These biosensing platforms will provide high-throughput, cost-effective, selective, sensitive and continuous monitoring of heavy metal ions in effluents from mining and mineral processing industries in a real-time fashion.
