Welcome

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Dr. András Paszternák, founder of Nanopaprika

what is the minimum temperature requirement for gold nanoparticle production?
Permalink Reply by N R Karthikeyan on June 5, 2009 at 10:16pm
Hi....to my understanding.... nanoscale Au can be produced by various techniques...to name a few VCLDI, EEW, Chemical route, phyiscal methods etc.... all these techniques doesnt yield nanoparticles of same size, shape, purity etc.... generally depending on the applications the synthesizing techniques is chosen...and each technique has its own temp requirements.... and finally one technique which most widely used for nano colloid preparation is thru reduction of Au(CN)3.. and this process is room temperature....on the other hand plasma process will require higher end temperature.... do correct me if i am wrong...

Thank you KARTHIKEYAN
what will be optimum temperature for the mechanical grinding to produce gold nanoparticles
Permalink Reply by N R Karthikeyan on July 2, 2009 at 5:53am
sorry for the delayed reply... i was suffering from chicken pox and was nt in the lab for couple of weeks... by the way... as for as mechnical grinding is concern... we have nt tried in the my lab..i mean gold mech. grinding.. bt then.. as such there is no much important is given to temperature... furthermore since gold is very very ductile metal...mech grinding will and should be done in cryo condition in order have significant size reduction...

Hi I am shashi here. when I prepare gold nanoparticles using aquas method (HAUCl3 and sodium citrate) , I keep temp 120 -130 degree.. Genereally I prepare 20-40 nm size gold particles

regards
shashi

i am working on biosynthesis of gold and silver nanoparticles from algae
Permalink Reply by BAIJU G.NAIR on June 10, 2009 at 6:01am
are you talking in terms of the living temperature of algae or a generalized gold preperation
Permalink Reply by Dr. Murugesan Subbiah on June 18, 2009 at 5:31pm
not living temperature.

is it the incubation temperature of algae? what is the optimum temperature of the algae for this methods?
