| Abstract | Powder like samples named MVPS, containing 95.8% of polysaccharide, were extracted from a well-known marine bivalve Mactra veneriformis. Some in vitro tests were carried out to characterize its physicochemical properties. X-ray diffraction and thermodynamics tests indicated that MVPS were noncrystalline but thermostable polymers. Solubility and rheology tests showed that MVPS could easily dissolve in aqueous media and its solution obviously belonged to non-Newtonian fluids even at relatively high concentration. Furthermore, via blending MVPS solution with other polymers and then spray drying the blends, several composite microparticles were prepared. The chitosan/MVPS particles are available not only with spherical morphology but also with higher production yield. As a model drug, metformin can be encapsulated into the composite microsphere and then achieve the sustained release. The chitosan/MVPS composite microspheres loaded with drug might be an appropriate for nasal formulation since its particle sizes are in the range of 1-10 µm. |

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.
