Abstract: In this study, we report our work on the incorporation of ceramic nanofillers, within a poly(caprolactone) (PCL) nanofibrous scaffold by electrospinning and their advantages over the native PCL scaffold for bone tissue engineering applications. PCL is biocompatible, biodegradable, FDA approved biomaterial. It is one of the strong candidates for bone tissue engineering. It is bioinert and has good mechanical strength as compared to polymers like PLGA and chitosan. This thesis focuses on the incorporation of different ceramic nanofillers in nanofibrous PCL scaffolds and the changes caused due to its incorporation in the properties of the scaffold, in terms of their hydrophobicity, biocompatibility, mechanical strength and osteogenic potential. Ceramics are hard and brittle materials, mostly known to be osteoconductive. Ceramics while in a composite give the mechanical strength to polymers. They can also increase the biological response especially the bioactivity of the scaffold. Nanofillers used in our study were namely, silica nanopowder (nSiO2), halloysite nanoclay (NC), nano hydroxyapatite (nHAp) and multifunctional nano hydroxyapatite (MF-nHAp). Such a study involving these four particular PCL/nanofiller composite scaffolds for assessing their regenerative potential for the purpose of bone tissue engineering may not have been done ever before in our opinion. Here, in our study, we wanted to take advantage of properties of nanoceramics (nSiO2, NC, nHAp and MF-nHAp) for reducing the hydrophobicity of PCL and enhancing the scaffold properties like strength and osteogenic potential for bone tissue engineering. Also, we wanted to exploit the magnetic resonance (MR) contrast enhancement ability of the MF-nHAp. These MF-nHAp incorporated scaffolds were engineered in order to enhance the osteogenic potential as well as its MR functionality for its application in bone tissue engineering.
