| Abstract | Anodic aluminum oxide (AAO) is a self-organized nanostructured material that contains high-density, uniform cylindrical pores that are aligned perpendicularly to the surface of the materials. Therefore, AAO nanostructures are very useful templates for applications such as electrochemical detection of metal ions and fabrication of nanowires or nanotubes. We fabricated an AAO template thorough two-step anodizing as an electrochemical sensing electrode. Gold nanowire (GNW) was prepared via in-situ electrochemical deposition on the AAO template. Then, the GNW/AAO electrode was functionalized with 1,6-hexadecanethiol. In the electrochemical analysis, the electron signals of the GNW/AAO changed by combining mercury ion and the thiol group on the electrode. The amperometric response was determined in the presence of the mercury ions. Consequently, a proof-of-concept test showed that the GNW/AAO electrode is a possible tool that can act as a heavy metal ion sensor. |

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.
