| Abstract | Nanofibrous semi-synthetic polymeric nanocomposite scaffolds were engineered by incorporating a maximum of 15 wt% biopolymeric gelatin nanoparticles (nGs) into the synthetic polymer poly(ε-caprolactone) (PCL) prior to electrospinning. The effect of nGs in altering the physico-chemical properties, cell material interaction and biodegradability of the scaffolds was evaluated. Experimental results showed that the inherent hydrophobicity of PCL scaffolds remained unaltered even after the incorporation of hydrophilic nGs. However, breakdown of the continuous nanofibers into lengths less than 7 µm occurred within four to eight weeks in the presence of nGs in contrast with the greater than two year time frame for the degradation of PCL fibers alone that is known from the literature. In terms of cell-material interaction, human mesenchymal stem cells (hMSCs) were found to attach and spread better and faster on PCL_nG scaffolds compared to PCL scaffolds. However, there was no difference in hMSC proliferation and differentiation into osteogenic lineage between the scaffolds. These results indicate that PCL_nG nanofibrous nanocomposite scaffolds are an improvement over PCL scaffolds for bone tissue engineering applications in that the PCL_nG scaffolds provide improved cell interaction and are able to degrade and resorb more efficiently. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
