Fig. 2. Properties of cRGD-coated HSA [HSA(cRGD)]. (a) Preparation of HSA(cRGD)-Au. (b) Fluorescence imaging of a mouse bearing a tumor of SW620 cells treated with Cy7.5-labeled HSA (10 nmol) after 4 or 8 h. (c) The change in fluorescence due to complex formation between HSA(cRGD) and Au-Cou (ex: 425 nm/em: 465 nm). Data are presented as means ± s.d. n = 3.
