"Spicy world of NanoScience"
I have not experience on synthesis and manipulation of metallic colloids, but a simple separation process is the use of nonsolvent aliquots (normally alcohols, depending of your surfactant) on colloidal solution, accompanied of centrifugal treatments and using desiccator, May be, this paper can be useful.
Thank you very much Sir.
Thanks a lot ...
You can use microemulsion method for the synthesis of nanoparticles
Dear Kumar, I have
Asim are you looking at recovery of copper NP??
Depending on your needs, you might find the following paper of some value: J. T. Nurmi et al. "Recovery of Iron/Iron Oxide Nanoparticles from Solution: Comparison of Methods and their Effects" Journal of Nanoparticle Research 2011 13(5) 1937-1952.
You can use centrifuging at 5000-6000 rpm for 10-15 minutes. This
can be further dried at moderate temperature. Also it would be good to
All the best.
I have not experience on the copper , but h hope good luck for you dear>>>> i have qesution for what you need copper NPS????????????
First u have to centrifuge your sample . you try the rpm range from 3000 to 10,000 rpm depending up on your particle size. larger the particle size lower rpm is enough. Then you can see the copper nanoparticle at the bottom remove the filtrate. Further the trace of the solvent is removed by vacuum. if u heat to remove water some times nanoparticle change it's morphology.
centrifuge it for many times to remove excess DI water and form as a slury. then pour it on petridish and dry it in proper environmental condition which u need.
