| Abstract | Fabrication of nanofibers with some biomaterials based on natural materials (collagen) through electrospinning is an important area for research. The effect of collagen coating on polycaprolactone (PCL) nanofiber surfaces was studied here. In this work, PCL nanofibers with titanium dioxide (TiO$_{2}$) nanopowder were used for the development of active wound dressings. We used glacial acetic acid as an environmentally benign solvent. The prepared nanofibers were coated with collagen by soaking the scaffold in 10 mg/mL and 20 mg/ml collagen solution overnight. The samples produced were subjected to contact angle measurements, SEM, FTIR, and XRD, and mechanical strength was determined. Nanofibers in the range of 200–800 nm were produced. The other study confirmed the physical interaction between collagen and PCL. The hydrophilicity of PCL nanofibers was increased; this was confirmed by observing contact angle values. A hydrophilic surface on the scaffold is necessary for biomedical applications. FTIR have proved the presence of an amide group on the PCL structure that facilitates cell adhesion and proliferation. SEM images have clearly proved the formation of nanofibers as well as the attachment of collagen to PCL nanofibers. XRD has shown the crystalline nature of the PCL polymer. PCL can impart more mechanical strength, although incorporation of collagen has decreased the tensile strength to some 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.
