**1. Introduction**

Despite the progress in wound dressing materials and also the level of expertise within the skilled discipline, the wound healing management still remains inconclusive [1]. The reason could be the price management of wounds is more and also the increasing population size and metropolitan lifestyle. These facts indicates towards the increasing demand for development of wound dressings that are effective, acceptable and cheap. In the year 2012, 184 million pound was spent on wound dressing merchandise in England [2]. Similarly, in the USA, annually approximately 20 billion dollar is spent on the management of chronic wounds [3, 4]. There are some barriers like educational, organisational, clinical and psychosocial for successful and effective treatment of wounds [5]. Biomaterials, biopolymers, synthetic polymers are the raw materials for preparation of wound dressing materials. Properties of biopolymers should be non-toxic, easily accessible, perishable, biocompatible and non-immunogenic like chitosan, alginate, fucoidan, mucopolysaccharide etc. [6, 7]. Due to the non-toxicity, biocompatibility, non-immunogenicity, affordability and high absorption capability specific and selective properties of polymers, alginates are best suitable used for dressing materials for wound dressing

purpose [8]. However, due to poor mechanical property of biopolymers they are incorporated with artificial polymers to boost their mechanical properties and tailored to change their degradation mechanism [1, 6, 7].

Alginate is a polysaccharide, generally used as bio-polymericmaterial for wound dressing [1]. It is a known and naturally collected biopolymer used in the management of wound dressings because of its selective characters like biocompatibility, nature of gelling and swelling, which creates moist and microenvironment at the damaged site enhancing the healing mechanism and declining the period of heling [1, 9]. The special properties of alginate convert it a model biopolymer with potential value, which might overcome the drawbacks related to other biopolymers used as wound dressing material [9, 10]. Alginate has already been incorporated within selective biomaterials for formulations of hydrogels, films, foams, gels, wafers, nanofibers, topical formulations, and several other novel systems for wound dressing [1, 9, 11]. Alginates are also utilised to prepare sponges as wound dressing products [1, 12]. The haemostatic property of alginate made appropriate for bleeding wounds also [13]. As alginate based hydrogel products are extensively used in tissue recreation and also acceptable in highly damaged wounds, these systems are most preferable in case of wound healing process [12, 14, 15].
