The aim of this study was to investigate the structural, thermal, optical and biocompatibility properties of poly(acrylic acid)(PAA)/organo-modified nanohydroxyapatite (OM-nHAp) nanocomposites synthesized by solvent intercalation method. The characterization of PAA/OM-nHAp nanocomposites was made by different techniques. SEM and TEM results showed that OM-nHAp particles were dispersed in the nanoscale into PAA matrix and that they were uniformly distributed within film. Glass transition temperature of PAA increased with OM-nHAp content. Ultraviolet (UV) absorbance experiments showed that PAA had a higher UV transmission than its nanocomposites. The biocompatibility of nanocomposites was also examined in simulated body fluid.

In this study, it was aimed to synthesize hydrogel based antibacterial, biocompatible and non-toxic wound dressing materials by solvent removal method usingpoly(vinylalcohol) (PVA), poly(vinylpyrolidone) (PVP) and nano pomegranate seed (PN).The morphology, swelling capacity, contact angle, antibacterial activity, biocompatibility and cytotoxicity of the synthesized films were determined. From the experimental findings, it was found that the PN particles were nano-sized, showed homogeneous and spherical distribution and improved the hydrophobic properties of the materials obtained by the addition of PN. And also, their swelling capacities were decreased with increased PN amount and all of the materials showed similar antibacterial activity, hemocompatibility and cytotoxicity.
