Bellamkonda Histological Slices (IMAGE) Georgia Institute of Technology Research News Caption Fluorescent microscopy breast tumor images that demonstrate the intensity changes in the X-ray images were caused by the nanocarrier and not endogenous changes in the tumor tissue. (A) 48 hours after injecting liposomes tagged with a red fluorescent dye, the liposomes appear in a patchy distribution in the periphery of the tumor. (B) A green immunohistochemical microvascular stain reveals the tumor has a highly vascularized peripheral rim and a less vascularized inner core. (C) In the same histological slice, the nanocarriers containing red contrast agent appear localized within the well vascularized rim.
