| Abstract | Synthesis of silver nanoparticles (NPs) has been performed using partially hydrolysed star-shaped graft copolymer of polyacrylamide to dextran as auxiliary capping agent. The star-branched copolymer proved to be a very good template for NP synthesis due to high local concentration of functional groups. Good biocompatibility of the copolymer was confirmed by phagocytic index value equal to 84%. In addition to this, the green synthesis approach was ensured using glucose as non-toxic reducing agent. Surface plasmon resonance spectra of the obtained NPs contained two characteristic bands situated at 270–300 and 420–450 nm. Transmission electron microscopy revealed that NPs synthesised in neutral solution (pH = 7) have average diameters equal 10–60 nm with a small portion of NP aggregates. Synthesis carried out at pH = 12 resulted in increased yield of NPs probably due to increased reducing power of glucose in alkaline medium. NPs synthesised in alkaline solution were sized from 20 to 300 nm and contained a large portion of NP aggregates. |

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.
