Nanomedicine for Mucosal Delivery

Research area overview

Nanomedicines represent the next generation of advanced therapeutics. These can be designed to carry the drug specifically to target disease site (cell or tissue) so that unnecessary exposure of healthy tissue to the drug is minimised and drug side effects are reduced. They also offer significant potential in enabling oral administration of drugs currently requiring injections (e.g. insulin). Nanomedicine therefore offers advantages in terms of drug safety, efficacy and patient convenience.

Our nanomedicine research centres around the use of nanosystems to enable mucosal (non-invasive) delivery of therapeutics that currently require injections. 

As part of this research, we are also interested in the study of the behaviour of drug delivery nanosystems at the interface with the mucosal surfaces and within the complex environments of the gastrointestinal system and the lungs.
