	abstract = {<p>Delivering drugs directly to the inflamed intestinal sites to treat inflammatory bowel disease (IBD), particularly Crohn{\textquoteright}s and ulcerative colitis, is highly challenging. Recent advances in colitis therapy medications are expanding opportunities for improving local on-site drug availability by minimising the associated systemic side-effects. Drug delivery with targeted carrier systems has shown the potential to increase site-specificity, stability, and therapeutic efficacy. Herein, we report the development of a strong anionic charged inflammation targeted nanocarriers (IT-NCs) loaded with an immunosuppressant model drug. This system showed preferential adhesion on a charge-modified surface in vitro, and in both dextran sulfate sodium (DSS) and TNBS colitis mice in vivo models. IT-NCs showed improved colitis phenotype therapeutic efficacy in both animal models compared to free drug. Furthermore, ex vivo study of colon tissue biopsies from patients with colitis revealed that IT-NCs adhered preferentially to inflamed biopsies compared to normal. Together, our results suggest that IT-NCs have promising therapeutic potential as delivery carriers{\textquoteright} in colitis management.</p>
