Dear all,
Does pH of the reaction mixture has any effect on biogenic synthesis of nanoparticles?
Please explain.
You can see in following papers (the effect of pH on nanoparticles size):-

Yes, pH affects size of nano particles during precipitation slow growth of particles depends upon solution of pH.

The pH definitely affects the size of nanoparticles. The main reason is charge on the surface of a nanoparticle present in a base fluid. This can be explained with zetapotential of a nanofluid. If zetapotential of a nanofluid is less than absolute value of 20 mV, the nanoparticle will have a greater size because of lower stability. If the absolute value of zetapotential is greater than 35, the size of nanoparticles tend to be smaller.
