Is it possible that nanoparticles can have varied antifungal properties in liquid and solid media? Is the interaction more in the liquid media and hence the greater activity?
Yes, the anti-fungal activity of the particles in liquid media, where they are freely move and interact with the fungi, is expected to be higher that in the solid media.
However, in addition to the diffusion coefficients, mentioned by Alan, there are another factors that affect the interaction, because the interaction is a system property and not a material property. These includes:
