Ultrasound-assisted biosynthesis of gelatin-gold nanocomposite: investigation of its antioxidant activity and its performance as anti-endometrial cancer in vitro
The current study outlines the simple process of designing Au nanoparticles (NPs) under mild conditions using gelatin as a natural capping and reducing agent. Through the use of UV–Vis (ultraviolet–visible), FT-IR (Fourier transform infrared) spectroscopy, TEM (transmission electron microscopy), FE-SEM (field emission scanning electron microscopy), EDX (energy-dispersive X-ray spectroscopy), XRD (X-ray diffraction), and elemental mapping techniques, the formation of gold nanoparticles stabilized by gelatin (Au NPs@Gel) and their structural properties were investigated. Gelatin-capped Au NPs produced the spherical, lowest average particle sizes, ranging from 10 to 15 nm, according to the microscopic images. Additionally, Au NPs/Gelatin showed a notably high percentage of cytotoxicity when tested against common human endometrial cell lines, such as AN3-CA and HEC-1-A, but a very low percentage of toxicity when tested against normal cell lines. Au NPs@Gel showed the strongest anti-endometrial effects against the AN3-CA cell line. The DPPH (2,2-Diphenyl-1-picrylhydrazyl) experiment was employed to examine the antioxidant characteristics of the Au NPs@Gel bio-composite, with BHT (butylated hydroxytoluene) serving as the positive control. IC50 of the Au NPs@Gel material was found to be 213.8 µg/mL in the DPPH assay. Antioxidant activity of the Au NPs@Gel was strongly correlated with its capacity to prevent endometrial cancer. According to the aforementioned results, Au NPs@Gel may be used to treat a variety of human cancers.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
