In the present study, we synthesized a Schiff base (L 1) derived from L-phenylalanine with furfuraldehyde and its Pt(II) complex ([Pt(L 1)(L 2)]: [Pt(N-(furfuralidene)phenylalanine)(8hydroxyquinoline)]) in the presence of 8-hydroxyquinoline (L 2). The chemical structures of the synthesized Schiff base and Pt(II) complex were characterized using ESI-MS, UV-Visible, FT-IR, 1 H NMR, 13 C NMR, and powder-XRD spectroscopy. The surface morphologies and elemental composition were determined by SEM and EDX. Thermal analysis was performed with TG-DTA. Mole ratio of Meyer and Job methods were used for the composition of complexes. According to these methods, the ratio [Pt 2+ ] : [L 1 + L 2 ] was found to be 1 : 1. In addition, the antimicrobial activities of L 1 and the complex showed that the compounds have significant antibacterial and antifungal properties. They also show important cytotoxic effects against the growth of mouse embryo fibroblasts (MEF) and human prostate adenocarcinoma (Du145) cancer cells. L 1 , L 2 , and the Pt(II) complex also displayed effective antioxidant activity.

In previous studies much research has reported the determination of applications of TiO2 (rutile and anatase), ZnO and Ag nanomaterials onto various textile surfaces, but in this study for the first time application to denim fabric and testing of the finished fabric for antimicrobial activities of these nanomaterials was investigated. The presence of nanoparticles on dyed denim fabric surfaces was confirmed by Scanning Electron Microscope (SEM). The nanomaterial-impregnated denim fabric (100% cotton) showed significant antibacterial activity against Staphylococcus aureus, Escherichia coli and Escherichia coli isolated from pasta. Additionally, the UV tests indicated excellent improvement in the UV absorbing activity of the TiO2 (rutile and anatase), ZnO and Ag nanomaterial-treated fabrics.
