Figure Lengend Snippet: Scheme 1 – In this work, FMDA/Gd 3 + /DOX was prepared for enhanced cancer theranostics. Due to the specific binding ability between fucoidan and p-selectin, this novel theranostic agent could effectively accumulate into tumor site by simultaneously targeting to the activated paltelets and tumor cells, thereby resulting in an enhanced MRI-guided chemo-photothermal combination therapy of HCC.

Figure Lengend Snippet: In vitro targeting ability and anti-cancer evaluation. (A) CLSM images of thrombin-activated and non-activated platelets treated with FMPDA/Gd 3+ /DOX or MPDA/Gd 3+ /DOX for 30 min. In the case of competitive assay, thrombin-activated platelets were pretreated with Anti-CD62P antibody for 30 min. (B) CLSM images of LM3 cells treated with FMPDA/Gd 3+ /DOX or MPDA/Gd 3+ /DOX for 1 h or 6 h, respectively. In the case of competitive assay, LM3 cells were pretreated with Anti-CD62P antibody for 30 min. (C) CLSM images of LM3 cells after incubating with FMPDA/Gd 3+ /DOX or MPDA/Gd 3+ /DOX for 1 h, in the presence of absence of the activated platelets. (D) The cell viability of LM3 cells treated with free DOX, MPDA/Gd 3+ /DOX or FMPDA/Gd 3+ /DOX at different DOX dose for 48 h. (E) The cell viability of LM3 cells treated with different concentrations of FMPDA/Gd 3+ or FMPDA/Gd 3+ /DOX for 12 h, followed by the treatment with or without NIR irradiation (2 W/cm 2 , 5 min) and then incubation for another 2 h. (F) The fluorescent images of survival LM3 cells in different treatment groups (MPDA= 80 µg/ml). (* P < 0.05, ** P < 0.01, *** P < 0.001, **** P <0.0001, n = 5).
