Fig. 2From: Slow release anti-fungal skin formulations based on citric acid intercalated layered double hydroxides nanohybridsInterlayer arrangement of citrate ion within the layers of Mg-Al LDH. The inter-layer arrangement was derived based on the basal spacing observed for the citrate LDH (1.20 nm) and the theoretical molecular size of citrate ion (0.72 nm)Back to article page
