Structurally Nanoengineered Antimicrobial Polypeptide Particles (SNAPPs)
Grant number: DP160101312 | Funding period: 2016 - 2020
This project aims to develop a new platform technology for the development of antimicrobial agents by combining expertise in polymer science and antimicrobial studies. It aims to develop new nanoengineered particles for combating antibiotic-resistant bacteria, investigate the influence of particle architecture on antibacterial properties, and determine the mechanism of action. This may support the development of antibiotic treatments using new polypeptide particles as antibacterial drugs, resulting in advances in nanobiotechnology, polymer therapeutics and advanced materials. The outcomes may revolutionise the synthetic approach to antimicrobial peptides and contribute significantly towards ..View full description
