Grafting of Natural Polymers and Gums for Drug Delivery Applications: A Perspective Review.
Natural polymers have received more attention because of their advantages over synthetic polymers such as abundant availability, low cost, biodegradability and non-toxicity. However, natural polymers suffer some limitations such as drop-in viscosity upon storage, uncontrolled hydration, solubility, inability to perform under high temperature and pressure (thermal stability), etc. In many instances above mentioned drawbacks of natural polymers limits their applications in drug delivery systems. Grafting of natural polymer leads to improved properties and characteristics of backbones of macromolecules such as improvement in gel strength, swelling index, mucoadhesion, drug targeting and drug release profile. Therefore, in recent decades grafting of the natural polymer has gained immense importance for the development of drug delivery systems. In addition to the pharmaceutical applications graft copolymers are extensively utilized in diversified fields. The present review is an attempt to define the grafting, various methods of polymer grafting and their application in drug delivery.
期刊介绍：
Therapeutic uses of a variety of drug carrier systems have significant impact on the treatment and potential cure of many chronic diseases, including cancer, diabetes mellitus, psoriasis, parkinsons, Alzheimer, rheumatoid arthritis, HIV infection, infectious diseases, asthma, and drug addiction. Scientific efforts in these areas are multidisciplinary, involving the physical, biological, medical, pharmaceutical, biological materials, and engineering fields.
Articles concerning this field appear in a wide variety of journals. With the vast increase in the number of articles and the tendency to fragment science, it becomes increasingly difficult to keep abreast of the literature and to sort out and evaluate the importance and reliability of the data, especially when proprietary considerations are involved. Abstracts and noncritical articles often do not provide a sufficiently reliable basis for proper assessment of a given field without the additional perusal of the original literature. This journal bridges this gap by publishing authoritative, objective, comprehensive multidisciplinary critical review papers with emphasis on formulation and delivery systems. Both invited and contributed articles are subject to peer review.
