| Abstract | In this study adherent animal cells were grown to confluence on circular gold-film electrodes of 250 µm diameter that had been deposited on the surface of a regular culture dish. The impedance of the cell-covered electrode was measured at designated frequencies to monitor the behavior of the cells with time. This approach is referred to as electric cell-substrate impedance sensing or short ECIS in the literature. The gold-film electrodes were also used to deliver well-defined AC voltage pulses of several volts amplitude and several hundred milliseconds duration to the adherent cells in order to achieve reversible membrane electroporation (in situ electroporation=ISE). Electroporation-assisted introduction of membrane impermeable molecules into the cytoplasm was studied by using FITC-labeled dextran molecules of different molecular weights. Probes as big as 2MDa were successfully loaded into the cells residing on the electrode surface. Time-resolved impedance measurements before and immediately after the electroporation pulse revealed the kinetics of membrane resealing as well as subsequent changes in cell morphology. Cells recovered from the electroporation pulse within less than 90 min. When membrane-impermeable, bioactive compounds like N(3)(-) or bleomycin were introduced into the cells by in situ electroporation, concomitant ECIS readings sensitively reported on the associated response of the cells to these toxins as a function of time (ISE-ECIS). |

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.
