In a paper, I saw the synthesize of silver nanoparticles using ethanol and PVA(poly vinlyl alcohol). I exactly followed the same procedure as they did. But, as ethanol is very volatile, most of the ethanol is lost by evaporation during the synthesizing procedure because it requires heating. How do I overcome this problem?
I am attaching the paper
Hi Sibasish, in cases when you heat/boil any solution/dispersion, you should equip your reaction flask with reflux condenser which will cool down and condence vapor of solvent. See link below:

If you do not use R.C., you will loose part or completely your solvent during heating. Hope it will help.
Best wishes.

I am satisfaction reply Horechyy Andriy . Please follow this reflux condenser when you heat solution/Solvent on dispersion .
use reflux condensor and teflon. If possible do the reaction in water-ethanol mixture if you want to use without condensor which will prevent the loss to some extent.
Dear brother,
If you are synthesizing nanoparticles through green nanochemistry, than use water as a medium for the synthesis of nanoparticles, which is more advantageous than ethanol.
