Au nanoparticles by instant green chemicals and optimising key synthesis parameters using Taguchi method

摘要

In the recent years, functionalised Au nanoparticles using eco-friendly chemical routes are under the focus for developing several technological applications. However, a simple, reproducible, and controlled synthesis of high-quality nanoparticles is challenging in these approaches. In this work, readily available green chemicals were utilised and the usefulness of and Taguchi approach for optimisation of synthesis procedure was designed for the synthesis of possible lower size Au nanoparticles of size 93 +/- 7 nm. L16 orthogonal array, by which the influence of four factors in four levels may well be tested, was chosen. Analysis of variance was done on the attained results and optimum condition suggested by statistical estimations was tested through a verification test. The identified key parameters for synthesising lower size Au nanoparticles are reducing agent (curcumin + cinnamic acid + citric acid), additive (zero), sonication time (30 min), and temperature (50 degrees C) after performing the optimisation technique. Furthermore, this study also provides a selective approach to obtain different shape/shape Au nano to colloidal structures through different trail selection within the Taguchi experimental array.
