| Abstract | Poly(hyaluronic acid) (p(HA)) particles with sizes from few hundred nm to few tens of micrometer were synthesized by using epoxy groups containing crosslinker glycerol diglycidyl ether (GDE) with high yield, 94±5%. P(HA) particles were oxidized by treatment with sodium periodate and then reacted with cationic polyethyleneimine (PEI) at 1:0.5, 1:1, and 1:2 wt ratio of p(HA):PEI to obtain p(HA)-PEI particles. From zeta potential measurements, isoelectronic points of bare p(HA) particles increased to pH 8.7 from 2.7 after modification with cationic PEI. New properties, such as antibacterial property, were attained for p(HA)-PEI after modification. The highest minimum bactericidal concentration (MBC) values were 0.5, 1, and 0.5mg/mL against Escherichia coli, Staphylococcus aureus, and Bacillus subtilis species for 1:0.5 ratio of p(HA)-PEI at 72h incubation time. Moreover, the p(HA)-PEI particles were found to be biocompatible with L929 fibroblast cells, and interestingly, p(HA)-PEI particles were found to inhibit MDA-MB-231 breast and H1299 cancer cell growth depending on amount of PEI in p(HA)-PEI particles. |

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.
