| Abstract | Near-field optics (NFO) overcomes the diffraction limit of light microscopes and permits single molecules to be imaged. Current NFO systems are designed to scan over the object being imaged and has found many applications in the physical sciences. However, there is a lack of tools that allow one to view intracellular processes, which would have many applications in the neurosciences, cancer studies and drug delivery fields. In this work, the authors have developed near-field optical probes, with nanometer apertures, that achieve much higher light throughput than conventional near-field fiber probes. The probes are designed to penetrate a living cell without destroying it. In parallel to this work, a microfluidic device has been designed and fabricated which is part of a high resolution imaging system the authors are developing. The microfluidic device or “CellTray” contains over 7000 individual wells that contain multiple cells. Together the optical probe and CellTray bring us a step closer to a lab-on-a-chip device for biomedical research. |

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.
