Advanced polymeric systems for minimally-invasive sampling of epigenetic and biomarker profiling for periodontal chronic wounds/Chronic wound biofluid sampling and analysis

In the last 10 years, epigenetic dysfunction has been associated with all major disease areas including infection and chronic wound management. The study of heritable changes in gene expression has become one of the fastest growing sectors of healthcare research and it is estimated that the global epigenetic market is expected to reach $22 Billion USD by 2025, with diagnostic applications across all major disease areas.

This project will look at developing novel diagnostic methods for minimally-invasive fluid sampling, to facilitate miRNA, related biomarkers, and epigenetic profiling in chronic wounds, such as periodontal disease (PD). PD is a common condition affecting the tissue and ligaments surrounding the teeth and is reported to affect >50% of the global population. Untreated, it can lead to gum inflammation, infection, and tooth loss. Small volumes of fluid, called gingival crevicular fluid (GCF) collect in the gaps, called pockets between the teeth and gums. Current GCF sampling techniques, such as micro-capillary pipetting and Perio-Paper® sampling, are not used routinely in practice owing to significant costs, variability in processing, potential for tissue damage, and the disruption of the healing process. Implementation of a non-invasive diagnostic device that could overcome the issues of GCF volume and handling difficulty, will facilitate earlier diagnosis and improved treatment outcomes in PD.

Underlying aim

To design and develop novel polymeric systems for the detection and quantitation of miRNA and biomarkers of inflammation in chronic wounds, such as periodontal disease.

Specific objectives/Methodology
