| Abstract | |
The search for more efficient and less aggressive cancer treatment methods has intensified over the last decades and has involved many scientific areas. To provide skin cancer patients with better quality of life, this work aims to incorporate chemotherapy into polyamide membranes, functionalized by the sol-gel methodology, for controlled drug release at the target tissue. A 200-micrometer-thick flexible polyamide membrane prepared by Additive Manufacture was activated and functionalized with the alkoxide 3-chloropropyltriethoxysilane, which was followed by incorporation of the antitumor agent cisplatin. Membrane functionalization with the alkoxide was attested by infrared absorption spectroscopy, which evidenced a band at 1100 cm(-1), due to Si-O-Si vibration, and typical cisplatin bands at 3200 and 1600 cm(-1). The thermogravimetric curve revealed increased silicon oxide and platinum residues. Drug release was tested in simulated body fluid. Cytotoxicity was evaluated by the Cell Proliferation Kit, which gave IC50 of 23.95 mu gM. (AU) | |
