We are dealing with the work entitled Synthesis of silver nanoparticle from plant. I have faced problem with particle size analysis by DLS. We got silver nanoparticle size in the micron range not in nano size, Can anyone send me the exact protocol for nanoparticle synthesis from water hyacinth plant?
Hi
I worked with water hyacinth and silver nanoparticles. I have a conference preecing in my profile which describe the process, or you can check papers from Genoveva Rosano Ortega
And i recommend you to use TEM or other tecnique for the size of nanoparticles
I hope this information could help you
The following patent may be of interest: G. E. Hoag, J. B. Collins, R. S. Varma, M. N. Nadagouda (Assignee: VERUTEK TECHNOLOGIES, INC.), "Green synthesis of nanometals using plant extracts and use thereof", United States Patent Application Publication, US 2010/0200501 A1, Aug. 12, 2010.
Please check by TEM whether you are getting nanoparticles or aggregation is taking place. If aggregation formation happens then one can try capping agents to stabilize the nanoparticles. Size of nanoparticles can be controlled by changing metal solution to extract ratio and varying incubation conditions. Use TEM to confirm the size.
