| Abstract | The antifungal activity of polyvinylpyrrolidone (PVP)-stabilized quantum-sized silver nanoparticles (SNPs) against the growth of Candida albicans has been demonstrated in the present study. C. albicans is a known opportunistic human pathogen causing superficial and systemic infections. Research data carried out on C. albicans so far have shown unequivocally that it develops resistance against conventional antifungal drugs and that the infections it causes are difficult to cure with conventional antifungal agents. Hence, it is urgent to find newer materials for the treatment of infections caused by C. albicans that must be safe for the host. PVP-capped SNPs were synthesized, and its surface plasmon band was observed at 410 nm. The growth of C. albicans was markedly inhibited when the cells were incubated with SNP. The minimum inhibitory concentration (MIC) of SNP was determined as 70 ng/ml, and this value is relatively lower when compared with the conventionally used antifungal drugs such as amphotericin B (0.5 µg/ml), fluconazole (0.5 µg/ml), and ketoconazole (8 µg/ml). The viability of SNP-treated cells was checked by measuring the metabolic activity using XTT assay. Field emission scanning electron microscopic (FE-SEM) and transmission electron microscopic (TEM) analyses of the cells treated with SNP have lost the structural integrity to a greater extent. |

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.
