| Abstract | Polysaccharide-based hydrogel scaffolds have emerged as promising candidates for skin regeneration. However, for restoring the integrity of the injured tissue, an appropriate balance of moisture and bioactivity needs to be maintained at the wound surface. Though several researchers have designed hydrogels from synthetic or natural resources, their applicability is restricted due to availability, cost and restricted properties suitable to specific wound types. In this study, a novel hydrogel composed of polysaccharide polymer from Moringa oleifera seeds and polyvinyl alcohol (MSP/PVA) was synthesized as a wound dressing material. The hydrogel was characterized using FTIR and XRD and evaluated for its fluid handling properties. It could absorb 5.7 g H$_{2}$O g$^{−1}$ dry weight with 20–30 % moisture being retained even after 24 h. Its good water absorption and donation ability make it appropriate for dry, necrotic and slightly exuding wounds. Its breathability and water vapor transmission rate extend it applicability to management of burns. The hydrogel exhibited hemocompatibility, antibacterial activity, bacterial impermeability, antioxidant activity and iron chelation that might help healing chronic wounds as well. It was biodegradable. In vivo wound healing showed that the rate of wound reduction and closure was accelerated with rapid re-epithelialization of partial thickness wounds in 6 days without scar formation. In vitro povidone–iodine loading and release studies showed that the iodine release followed Fickian diffusion process. The MSP/PVA hydrogel holds promise for management of dry, necrotic, slightly exuding, chronic wounds, burns and thus appears to be an economical alternative worth industrial exploitation. |

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.
