| Abstract | Low molecular weight (LMW) chitosan nanoparticles have attracted considerable attention as colloidal drug carriers, but when applied to intravascular drug delivery, they are easy to be removed from circulation by the reticuloendothelial system, which limits their applications as long-circulating or target-specific carriers. Erythrocytes have a long circulation time in the blood, but they are sometimes not suitable for loading and releasing of drug directly. The combination of LMW chitosan nanoparticles and erythrocytes that complement each other is a desirable strategy to develop a multifunctional drug carrier. In this study, monodisperse, LMW chitosan nanoparticles were prepared by ionic gelation technique and these nanoparticles were investigated with regard to their erythrocyte compatibility. Then the interactions between erythrocytes and fluorescence-labeled LMW chitosan nanoparticles were studied by confocal microscopy. The results of this study indicate that LMW chitosan nanoparticles show good compatibility with erythrocytes and they can be easily attached to the surface of erythrocyte membrane, suggesting that erythrocytes load of LMW chitosan nanoparticles can be served as a potential vascular drug delivery system. |

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.
