| Abstract | This study aims to investigate the transport of lipid nano-droplets through MDCK epithelial cell monolayer. Nanoemulsions of self-nano-emulsifying drug delivery systems (SNEDDS) labeled with radioactive C18 triglyceride were developed. The effect of droplet size and lipid composition on the transport was investigated. The results showed that the lipid nano-droplet transport through MDCK cell monolayer was as high as 2.5%. The transport of lipid nano-droplets was higher for nanoemulsions of medium chain glycerides than the long chain glycerides. The transport was reduced by more than half when the average lipid nano-droplet size increased from 38nm to 261nm. The droplet size measurement verified the existence of lipid nano-droplets in the receiver chamber only when the nanoemulsions were added to the donor chamber but not when the surfactant or saline solution was added. Cryo-TEM images confirmed the presence of lipid nano-droplets in both donor and receiver chamber at the end of transport study. In conclusion, lipid nano-droplets can be transported through the cell monolayer. This finding may help to further explore the oral and other non-invasive delivery of macromolecules loaded inside SNEDDS. |

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.
