Please explain, in green synthesis, in the ratio of precursor and plant extract, if the plant extract is increased, nano-particles will be increased or not?
How can be decide the exact ratio of precursor and plant extract for the synthesis of nanoparticles?
Plants and their extract contained metabolites such as amines, amino acids, aldehydes, ketones, carboxylic acids, phenols, proteins, flavonoids, saponins, steroids, alkaloids, tannins and different types nutritional compounds which have been successfully and frequently used in green synthesis of nanoparticles. In this process, many phytochemicals act as reducing agents to produce nanoparticle from metal salts. Their production rate and size are controlled by monitoring the concentration, pH and temperature of plant extract and that of the salt. So, this depends on plant species and their parts; and need to be standardized for desired rate of production. Furthermore, altering of these growth factors in the synthesis medium could produce the desired morphology of required nanoparticles. Please check some attached published review papers for further information.
Dear S. P. Goutam
in this paper Taguchi design was applied to improve the physicochemical conditions for nano-Ag production, and the optimum conditions.
You can use this software and optimization method.
hi and thanks for your attention to our works.
the silver nonoparticle size can be variable with parameters such as extract concentration. so you can read our previous papers for more information.
Dear Goutam
To find the optimum precursor ratio of precursor and plant extract, you have to check with experimentally, before that we cannot say which is exact concentration. In some cases, by increasing amount of plant extract size of NPs will be increased or vice-versa.
Check our recent article of green synthesis of silver NPs regarding this.We have check the effect of plant extract volume on the size of of Ag NPs
