Green Assisted Tool for Nanogold Synthesis Based on Alginate as Biological Macromolecule

Popis výsledku v původním jazyce

Large scaled biomedical applications of nanogold were reflected in challenging of recent researches for investigation of green synthesis methodologies, which is mostly complicated in processing and/or expensive. The presented report offers totally green method using quite simple and costless technique for Au nanoparticles manufacturing based on alginate macromolecules. Hydrogen peroxide was used for oxidative degradation of alginate at room temperature to produce more accessible fragments, beneficial for reduction of Au ions to Au0, and stabilizer for the produced nanogold. The competence of the mentioned procedure was tested by comparing with alkali/glucose/alginate system, in which glucose and alginate were used as reducer and stabilizer, respectively. For both systems, surface plasmon resonance peak for nanogold was detected and similar absorbance spectra were observed. Using either 30 mmol/L H2O2 or 1 g/L glucose, similar reducing sugars content (0.32 g/L) was resulted from 1 g/L alginate. Nanogold manufactured by H2O2 exhibited smaller size (3.7 ± 1.1) with narrower size distribution (1.5 – 8.0 nm) rather than that produced in case of glucose
