The self-assembly of pifithrin-α-loaded layered double hydroxide/chitosan nanohybrid composites as a drug delivery system was demonstrated for the first time to improve the cytocompatibility and enhance the osteoinductivity for the treatment of bone defects.

Nanohybrid Material

An organo-mineral nanohybrid material in which the organic moiety is interleaved inside the inorganic lamella was prepared by using phenoxyacetate anions as a guest in the Mg-Al-layered double hydroxide lamella (as an inorganic host) by the self-assembly technique, anion exchange and the reconstruction methods. The powder XRD patterns of the resulted materials show that the basal spacing of the Mg-AI-layered double hydroxide with carbonate as the counter anions expanded from 7.7 ? to around 16.6 ? in the nanohybrid materials. IR studies show that the absorption bands of the resulting materials correspond to the characteristic functional groups of the host and the guest structures. When the two results are taken together, the expansion can be attributed to the intercalation of the phenoxyacetic acid in the inorganic interlamella for the formation of the nanohybrid material. The intercalation of phenoxyacetate anions was also confirmed by thermogravimetric analysis (TG).

Layered double hydroxide (LDH) hybrid materials of Zn-Al-layered double hydroxide-3,4-dichlorophenoxy acetate acidnanocomposites (ZADs) were prepared by direct self-assembly method. The pH of the solution was adjusted to 7.5 using 2M NaOH. Various Zn2+ to Al3+ molar ratios, R ranging from 1 to 6 were used with a fixed concentration of 3,4-D at 0.3 M. The Powder X-ray diffraction (PXRD) patterns showed the formation of well-ordered nanocomposite with the expansion of basal spacing from 8.9 Å in the Zinc-Aluminium-Layered Double Hydroxide (ZAL) to 18.7 - 22.1 Å in the resulting nanocomposites. The Fourier transform infrared (FTIR)spectra for the nanocomposites showed features for both ZAL and ZAD, showing the successful intercalation of the organic moiety into the LDH interlayer. The percentage loading of 3,4-dichlorophenoxy acetati acid(3,4-D) in LDH was found to be increased from 34.7-48.1 % (w/w), as the mole fraction of Al decreased from 0.44-0.15. This study shows that the mole fraction of zinc ion was replaced by aluminium ion in the LDH plays an important role in controlling the physic-chemical properties of the resulting material.
