Silk fibroin is a type of natural polymer that has good biocompatibility, biodegradability and is also easy to modify. It also possesses low cytotoxicity and is non-immunogenic and therefore it is widely used for the delivery of anti-tumor drugs. Most anti-tumor drugs suffer from low solubility, poor pharmacokinetics and high off-target toxicity. Therefore finding and developing appropriate drug delivery systems is urgently requires to solve these problems and improve the treatment of patients. This paper briefly reviews the structure and characteristics of silk fibroin, the preparation and the different types as well as the research progress of silk fibroin nanocarriers for anti-tumor drugs delivery. This paper also summerizes the research progress of silk fibroin nanocarrier application in photodynamic, photothermal and gene therapy for the treatment of malignant tumors. Based on our summery, silk fibroin has prospects for a broad application as a delivery system of anti-tumor drugs. Therefor it seems that silk fibroin will be a promising and important carrier material for novel formulations of anti-tumor drugs.
