Fig. 8From: Improving anti-cancer drug delivery performance of magnetic mesoporous silica nanocarriers for more efficient colorectal cancer therapyRepresentative ex vivo fluorescence and magnetic resonance imaging (MRI). Fluorescence images taken for main organs (liver, kidney, spleen, heart, and lung) and tumor at A 12 and B 24Â h after injection of free DOX, PEG-Au-NPs@DOX and Apt-PEG-Au-NPs@DOX (DOX final concentration was 1Â mg/kg). The T2-weighted coronal and axial images of the HT-29 tumor bearing C57BL/6 mice 12Â h post injection of C PBS, D PEG-Au-NPs@DOX and E Apt-PEG-Au-NPs@DOX. The areas of the tumor are marked with a circle.
