| Abstract | Bifunctional magnetic-fluorescent Fe3O4@SiO2@ZnS nanocomposites were synthesised by a chemical deposition method. The Fe3O4 magnetic nanoparticles as the core were obtained by means of a solvothermal reaction with SiO2 as the shell. ZnS particles were linked to Fe3O4@SiO2 core–shell nanostructures. The morphology and properties of the resultant Fe3O4@SiO2@ZnS nanocomposites were investigated by X-ray diffraction, field emission scanning electron microscopy, high-resolution transmission electron microscopy, a vibration sample magnetometer and fluorescence microscopy. The results showed that bead-like structures were built from numerous Fe3O4@SiO2@ZnS microspheres with an average size of 250 nm. The saturation magnetisation (M s) value of Fe3O4@SiO2@ZnS nanocomposites was 22.41 emu/g at room temperature. Furthermore, a strong blue light emission was observed from the nanocomposites under UV light irradiation. The combination of magnetic and fluorescent properties may lead to Fe3O4@SiO2@ZnS nanocomposites having a variety of potential applications in the field of biomedicine, such as bioimaging and cell separation. |

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.
