| Abstract | A compact portable chemiluminescent biosensor for simple, rapid, and ultrasensitive on-site quantification of fumonisins (fumonisin B1+fumonisin B2) in maize has been developed. The biosensor integrates a competitive lateral flow immunoassay based on enzyme-catalyzed chemiluminescence detection and a highly sensitive portable charge-coupled device (CCD) camera, employed in a contact imaging configuration. The use of chemiluminescence detection allowed accurate and objective analyte quantification, rather than qualitative or semi-quantitative information usually obtained employing conventional lateral flow immunoassays based on colloidal gold labeling. A limit of detection of 2.5 µgL(-1) for fumonisins was achieved, with an analytical working range of 2.5-500 µgL(-1) (corresponding to 25-5000 µgkg(-1) in maize flour samples, according to the extraction procedure). Total assay time was 25 min, including sample preparation. A simple and convenient extraction procedure, performed by suspending the sample in a buffered solution and rapidly heating to eliminate endogenous peroxidase enzyme activity was employed for maize flour samples analysis, obtaining recoveries in the range 90-115%, when compared with LC-MS/MS analysis. The chemiluminescence immunochromatography-based biosensor is a rapid, low cost portable test suitable for point-of-use applications. |

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.
