Abstract

Chemotherapy is the gold standard for cancer treatment. However, the specific and safe delivery of chemotherapies to cancer cells remains a great challenge. Gold nanoparticles (GNPs) offer a promising solution as carriers for chemotherapy due to their biocompatibility and distinctive physicochemical properties that facilitate precise drug binding and enhanced tumor penetration through the enhanced permeability and retention effect. Here, we have designed GNPs bound to chemotherapies together with glucose coating and studied their cancer cell killing efficacy in a head and neck squamous cell carcinoma cell line. We found that the GNPs bound to chemotherapy had a higher cancer cell killing efficacy as compared to controls, as well as a bystander effect. This GNP-based platform holds promise, for advancing chemotherapy-based cancer treatments.
