| Abstract | A novel amphiphile containing two functional groups of both naphthalene and phenylboronic acid, p-((5-dodecyloxy-1-oxy) naphthalene) methyl-phenylboronic acid (DNMPBA), has been synthesized. The amphiphile has self-organized into vesicles in the selective solution of THF/water (phi=0.6) buffered at pH 6.86. The Tc of the vesicles from crystal to liquid crystal is 56.8degC. Addition of saccharides to the vesicular solution, the fluorescent intensities of naphthalene in DNMPBA vesicles centred at 345 nm increase dramatically with increasing concentration of saccharides. The changed tendency for fluorescent intensities of the DMNPAB vesicles with saccharides is similar to the other systems reported in literature to favor the binding with fructose over glucose and maltose. It is ascribed to boronic ester formation which might diminish the photoinduced electron transfer (PET) progress to induce fluorescence retrieval and, therefore, increase the fluorescence intensity. The vesicular sensor through the interactions between boronic acid and saccharides displayed at a biomimetic membrane interface can be detected by means of fluorescence intensities. The results suggest that the fluorescent vesicles might be used as biosensors to determine saccharides. |

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.
