Abstract

The epithelial lining of the gastrointestinal (GI) mucosal layer is an effective barrier to the contents of the gut lumen. Selective channels and tight junctions prevent contamination of the sterile internal environment of the body. Conversely, the gut barrier also prevents desired agents from entering the GI tissue. This hinders marking of tissue for further clinical follow-up. Focused ultrasound (US) may provide a potential means of overcoming the gut barrier and allowing penetration of material beyond it which was explored in a series of tests. Experiments were carried out on 14 individual postmortem-obtained murine small bowel samples for a total of 23 sonication/control paired tests. A favourable result of 80% indicated that focused US can pass a nanoscale fluorescent agent through the gut barrier. Further work is required to elucidate where the agent resides, intercellular or intracellular, post-sonication.
