pH-triggered surface charge-reversal nanoparticles alleviate experimental murine colitis via selective accumulation in inflamed colon regions

In this study, we developed, through intelligent design, pH-triggered surface charge-reversal lipid nanoparticles, which were shown to precisely deliver a corticosteroid drug to inflamed colon segments in an ulcerative colitis mouse model. The results of the study suggest that the pH-triggered charge-reversal lipid nanoparticles are a promising drug nanocarrier for colon-targeted therapy, including ulcerative colitis treatments.190
