Background: Esophageal cancer is one of the most prevalent malignant tumors and the sixth largest cause of tumor-associated death worldwide. Squamous cell carcinoma (ESCC) accounts for 85 % of all esophageal cancer cases. ESCC treatment remains to be significantly difficult.
View Article and Find Full Text PDFMelittin (MEL), the primary active component of bee venom, has recently emerged as a promising cancer chemotherapeutic agent. However, the instability and rapid degradation of MEL is a significant challenge in practical therapeutic applications. In the present study, graphene oxide (GO)-based magnetic nanocomposites (PEG-GO-FeO) were prepared and adopted as the drug delivery vehicles of MEL, and the anticancer effects of PEG-GO-FeO/MEL complexes on human cervical cancer HeLa cells were studied.

The resultant materials (Apt-MNPs) exhibited outstanding magnetic responsibility and can be separated efficiently by the magnetic field.

A single bi-functional monomer was adopted for preparation of the molecularly imprinted polymer, avoiding the tedious trial-and-error optimizations as traditional strategy. Moreover, bisphenol F was used as the dummy template for bisphenol A to avoid the interference from residual template molecules.
