Özet

In this study, biodegradable hydrogel films based on natural proteins and polysaccharides were synthesized in order to improve controlled drug release, cytocompatibility and antibacterial properties. Biosynthesized gold nanoparticles were incorporated in situ cancer drug-loaded hydrogels to enhance their antibacterial, biocompatible, and cytotoxic characteristics. Then, in order to investigate the association of silibinin drug used in cancer treatment with AuNPs, drug release profile was evaluated under different environmental conditions and release kinetics were analyzed. In addition, antibacterial effects were determined by testing on Gram-negative and Gram-positive bacteria by Disk Diffusion method. As a result, cytocompatibility of silibinin drug and AuNPs in hydrogel networks and their effects on cancer cells were determined by MTT assay using human dermal fibroblasts (CCD1079KSk) and colon cancer (HT-29) cell lines. Thus, AuNPs created a synergistic effect in cancer treatment and strengthened the effect of Silibinin on tumor cells. In addition, it was determined that it exhibited a biocompatible structure by showing minimal toxicity to healthy human skin cells. This innovative drug delivery system has the potential to offer a biomaterial-based alternative in both cancer treatment and wound dressing material with its controlled release feature.
