The high incidence of colorectal cancer worldwide is currently a major health concern. Although conventional chemotherapy and surgery are effective to some extent, there is always a risk of relapse due to associated side effects, including post-surgical complications and non-discrimination between cancer and normal cells. In this study, we developed a small molecule-based theranostic system, Gal-Dox, which is preferentially taken up by colon cancer cells through receptor-mediated endocytosis. After cancer specific activation, the active drug Dox (doxorubicin) is released with a fluorescence turn-on response, allowing both drug localization and site of action to be monitored. The therapeutic potency of Gal-Dox was also evaluated, both in vivo and ex vivo, thus illustrating the potential of Gal-Dox as a colorectal cancer theranostic with great specificity.
