| Abstract | Silver nanoparticles (Ag NPs) were green synthetized using xanthan gum (XG) dissolved in water as reducing and capping agent for the first time. The structure, morphology, and size of Ag NPs in XG aqueous solutions were investigated with UV-vis spectroscopy, transmission electron microscopy and Fourier transform infrared. The results indicated Ag NPs were integrated successfully in the XG matrix and the optical properties and morphology of Ag NPs could be regulated by the synthesis condition. The aggregation of the XG-bonded Ag NPs increased with storage, whereas the size barely changed. The assemble behavior was related to the XG conformation transition of denaturation and renaturation. The one spot formed Ag NPs showed favorable antibacterial effect on Escherichia coli and Staphyloccocus aureus and excellent catalytic capability of 4-nitrophenol reduction. This work provided a feasible method to detect the biopolymer space structure transition through the intensity of metal nanoparticles labeled on the chain. |

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.
