Ulcerative colitis (UC) is a lifelong inflammatory bowel disease characterized by periods of intense colonic inflammation leading to debilitating symptoms. Delivery methods of current UC treatments are suboptimal and associated with side effects. Silica particles are a potential alternative delivery method for UC therapeutics, given their promising drug-loading and safety profiles. However, it is unknown whether silica particles preferably accumulate at sites of colonic inflammation. This study aimed to correlate silica particle accumulation with colonic inflammation in a rat UC model.
