Diffusion of Resveratrol in Silica Alcogels
The trans-resveratrol (RSV)-loaded silica aerogel (RLSA) was prepared by the sol-gel method, adding the drug during the aging process, solvent replacement and freeze drying.A series of characterizations showed that RSV stays in the silica aerogel in two ways.First, RSV precipitates due to minimal solubility in water during the solvent replacement p
