| Summary: | A new layered organic-inorganic nanohybrid based on zinc layered hydroxide (ZLH) which contains an anti-inflammatory
agent, salicylate (SA) was synthesized through direct reaction of salicylic acid at various
concentrations with commercially available zinc oxide (ZnO). Power x-ray diffraction (PXRD) patterns revealed
that the basal spacing of the pure phase nanohybrid was 15.73 A. The SA anions were arranged in a vertical
bilayer form, with the carboxylate functional groups pointing towards the inorganic layers of ZLH. Fouri er
transform infrared (FTIR) spectrum for the synthesized nanohybrid illustrate ba'nds characteristic of salicylate and
ZLH, thereby further confirming its intercalation into the interlayers of ZLH. The loading of SA in the nanohybrid
was estimated to be around 29.7%, and the nanohybrid exhibited the properties of a mesoporous-type material.
Thermogravimetry and differential thermogravimetry analyses showed that the thermal stability of the SA in the
nanohybrid was greatly enhanced compared to its counterpart. In vitro cytotoxicity assay revealed that free SA,
pure ZnO and the nanohybrid have mild effect on Viability of African green monkey kidney (Vero3) ceils. |
