Does anyone here have an idea if there are glass Petri dishes available in market with a diameter of 25 mm?

I am trying to buy a Petri dish with a small diameter for nanofluid photo-thermal conversion experiment but the smallest diameter I found starts from 30-35 mm which doesn't fit my experiment...

How to perfectly get dry nanopartciles without losing any particles after an evaporation process for a colloid?

I have synthesised GNPs by plasma reduction method using HAuCl4 mixed with distilled water at different molar concentrations (from 0.05 to 1 mM). As a next step, I want to determine the Au NPs...

How to separate the unreduced gold salt from the reduced part (gold nanoparticles) after synthesizing.

I've synthesized surfactant-free gold nanoparticles by generating atmospheric-pressure microplasma on the surface of gold salt (HAuCl4.3H2O) aqueous solution (1 mM) for 10 minutes processing time...
