Figure 2From: Porosity and dielectric properties as tools to predict drug release trends from hydrogelsDSC endothermic thermograms of water molecules in hydrogels with heat flow (W/g) and temperature (°C). The linear arrow indicates onset temperature (Tos) and curved arrow shows melting point (Tm) of water confined into polymeric network of hydrogels (GT- gelatin; CT- chitosan; GC0.3-GC3 (gelatin-chitosan in ratio 1:0.3 to 1:3)).Back to article page
