Project description

Preliminary results indicate that not all hand sanitisers are effective at killing off bacteria (Ross et al 2020). The chemical composition of sanitisers varies a lot with some having 70% alcohol and others claiming to be alcohol free. This project will test a range of hand-sanitisers to identify 1) their effectiveness in killing colonies of a surrogate bacteria 2) their actual chemical composition by chemical analysis - Infra-Red spectroscopy and GCMS and LCMS. The aim is to not only to identify the effective and not effective sanitisers but also to find a correlation between the chemical composition (content and %) and the effectiveness of individual sanitisers.

Note: You need to register interest in projects from different supervisors (not a number of projects with the one supervisor).
You must also contact each supervisor directly to discuss both the project details and your suitability to undertake the project.
