Abstract

Resveratrol (Res) has emerged as an extremely promising natural molecule due to its vast therapeutic prospects. However, the potential of the drug is immensely hindered by several limiting factors including poor water solubility, limited chemical stability and high metabolization. Herein we report a facile synthesis of a Res-loaded folate-terminated PEG-phospholipid coated reduced graphene oxide nanoassembly (FA-PEG-Lip@rGO/Res) by simply sonicating Res and rGO in FA-PEG linked liposome (FA-PEG-liposome) suspensions. The as-obtained FA-PEG-Lip@rGO/Res exhibits a nanoscale size (148 ± 7 nm), a negative surface potential (−23.6 mV), an excellent drug loading (69.5 ± 4.3%), a high drug entrapment efficiency (86.9 ± 5.6%), good monodispersity and controlled release. Additionally, the nanoassembly can protect Res from UV-light induced instability. Owing to the folate mediated targeted delivery, the robust FA-PEG-Lip@rGO/Res can deliver loaded Res to human MCF-7 breast cancer cells with high specificity and excellent efficiency. The cell toxicity viability shows that unloaded FA-PEG-Lip@rGO has no cytotoxicity, confirming its suitability as a drug vehicle. Furthermore, a systematic in vivo study shows that, under near-infrared (NIR) laser irradiation, FA-PEG-Lip@rGO/Res exhibits highly efficient combined chemotherapy and photothermal therapy to eradicate xenografted tumor with a single dose intratumoral (i.t.) injection. Thus, a facile, stable, biocompatible, and highly-effective Res delivery system has been developed, which may greatly advance the application of Res in biomedical research.
