Fucoidan-based dual-targeting mesoporous polydopamine for enhanced MRI-guided chemo-photothermal therapy of HCC via P-selectin-mediated drug delivery.

ABSTRACT: The development of novel theranostic agents with outstanding diagnostic and therapeutic performances is still strongly desired in the treatment of hepatocellular carcinoma (HCC). Here, a fucoidan-modified mesoporous polydopamine nanoparticle dual-loaded with gadolinium iron and doxorubicin (FMPDA/Gd³⁺/DOX) was prepared as an effective theranostic agent for magnetic resonance imaging (MRI)-guided chemo-photothermal therapy of HCC. It was found that FMPDA/Gd³⁺/DOX had a high photothermal conversion efficiency of 33.4% and excellent T₁-MRI performance with a longitudinal relaxivity (r₁) value of 14.966 mM^-1·s ^- 1. Moreover, the results suggested that FMPDA/Gd³⁺/DOX could effectively accumulate into
