| Abstract | Cocaine is one of the most abused drugs in the United States and is potentially dangerous when consumed in excess. Its detection is thus important in many areas in the fight against drug trafficking. We have developed an amplified detection method for cocaine based on a strand-displacement polymerization reaction using aptamer recognition. The system mainly consists of a hairpin probe with Cy5 labeled on its 3' end, a primer with FAM labeled on its 5' end, and polymerase. The aptamer sequence is integrated into the 5'-section of the hairpin probe. The primer is designed complementary to the 3' end of the hairpin probe, which is also part of the hairpin stem region. The cocaine induced reaction cycle generates product for detection and thus for signal amplification. The detection limit of this method is 200 nM in about 16 min and the specificity of this approach is excellent. We believe that this strategy will be useful for the development of analytical schemes for a variety of aptamers for small molecules, metal ions, and proteins. This simple scheme employing the strand-displacement polymerization reaction may find wide application in forensic analysis, environmental monitoring, and clinical diagnostics. |

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.
