| Abstract | Marine biopolymer composite materials provide a technological platform for launching biomedical applications. Biomaterials demand good biocompatibility without the possibility of inflammation or foreign body reactions. In this study, we prepared two biocomposite hydrogels namely; HAC (hydroxyapatite, alginate & chitosan) and HACF (hydroxyapatite, alginate, chitosan & fucoidan) followed by calcium chloride cross linking. The prepared scaffolds were characterized by Fourier Transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Porosity measurement, swelling, biodegradation, hemolysis, RBC aggregation, plasma protein adsorption and cytotoxicity studies were also done. The hydrogel scaffold HACF possessed a well-defined porous architecture, sufficient water holding capacity, better hemocompatibility and biodegradability. The biocompatibility was confirmed through in vitro cytotoxicity studies such as MTT assay, Neutral red uptake (NRU), DAPI staining, Trypan blue dye exclusion test and direct contact assay in L929 mouse fibroblast cells. In addition, immunomodulatory and anti-inflammatory properties of both of these scaffolds were revealed by the mRNA expressions of major inflammatory marker genes in cytotoxic condition such as TNF- , IL-6 and NF-κB. The physiochemical characterization and biological responses of HACF hydrogel signifies its suitability for various tissue engineering applications. |

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.
