| Abstract | Many biomaterial scaffolds have been developed for use in tissue engineering usually for populating with a single cell-type. In this study we demonstrate the production of bilayer and trilayer nanofibrous/microfibrous biodegradable scaffolds suitable for the support, proliferation and yet segregation of different tissues – here used to separate soft tissue from bone forming tissue and keratinocytes from fibroblasts. Essentially we describe a nanofibre barrier membrane which is permeable to nutrients coupled with attached microfibers (either on one side or both sides) to support the proliferation of different cell types either side but prevents migration of cells across the barrier. Such membranes would be suitable for guided tissue regeneration in areas where one wishes to support both soft and hard tissues but keep them separated. We describe a sterile bilayer membrane electrospun from polyhydroxybutyrate-co-hydroxyvalerate (PHBV) (nanofibres) and polylactic acid (PLA) or poly ε-caprolactone (PCL) (microfibres) and a trilayer membrane electrospun in layers of PLA, PHBV, then PLA. These membranes are biocompatible, biodegradable and capable of supporting two different cell populations. |

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.
