| Abstract | Poly(methyl methacrylate) (PMMA) is a biocompatible polymer widely used for bone substitutes. Its surface properties, however, are not favorable for the induction of biological apatite which can be directly related to natural bone formation. In this study, the surface of PMMA was modified by NaOH treatment or sequential treatments with ethanol (EtOH) and NaOH. Results displayed that surface hydrophilicity was improved for increasing treatment time and NaOH concentration. Field-emission scanning electron microscope (FE-SEM) displayed that in vitro formation of calcium phosphate (CaP) coating was significantly promoted by the surface modifications. X-ray photon spectroscopy (XPS) examination elucidated that the films prepared on PMMA consisted of calcium and phosphorus and their values for Ca/P ratio were closed to octacalcium phosphate (OCP). Fourier transform infrared (FT-IR) spectra of the film coated on PMMA revealed a band characteristic of phosphate groups confirming that CaP films were formed and their characteristics were dependent on the surface properties of PMMA. Cellular assay demonstrated that the adhesion of osteoblast-like MG63 cells was significantly promoted on CaP-coated PMMA. Proliferation assay showed that CaP films appeared not to exert any cytotoxic effects on the growth of MG63 cells. |

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.
