| Abstract | An innovative, specific and label-free detection approach based on optical surface plasmon resonance (SPR) was developed and employed in the development of a rapid and quantitative bioanalyzer for detecting infectious bursal disease virus (IBDV) in the field. A unique bioanalyzer based on this approach was established which consists of a micro-flow cell, a temperature regulator, an integrated biosensor, an optical platform, an electronic control unit incorporated into a photoelectric conversion device, and a universal serial bus (USB) interface circuit board. The procedure for detecting IBDV was systematically described, and experimentally validated. The self-assembly technology was used to make the IBDmAb adhere to the surface of the sensor chip by a bifunctional cross-linker. By this approach there exhibited a linear relationship between the IBDV concentrations and the corresponding responses in the range of dilution factors from 100 to 1600 with R(2) 0.97982. We were able to detect 400-fold diluted IBDV using this biochip repeatedly with a calculated relative standard deviation (RSD) of 3.6%. We also showed that the detection limit of the SPR biosensor biochip was around 1/18 of the detection limit of the IBDV diagnostic strip. Satisfactory recoveries were obtained from the recovery test. The approach presented here was shown to have great potential to be used in the IBDV epidemic regions and hence help to promote the effective implementation of sound control strategies against IBDV. |

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.
