Biocomposites in therapeutic 1 application: current status and future Sabyasachi Maiti1, Sougata Jana1, Subrata Jana2 1Gupta College of Technological Sciences, Asansol, India; 2Indira Gandhi National Tribal University, Amarkantak, India 1.1 Introduction From the health care perspective, biomaterials can be defined as the materials that pos- sess some novel properties that make them appropriate to come into immediate con- tact with the living tissue without eliciting any adverse immune rejection reactions. The biomaterials can be divided into the following categories: (1) synthetic (metals, polymers, ceramics, and composites); (2) naturally derived (animal and plant derived); (3) semisynthetic or hybrid materials. The ensuing developments of these biomaterials have enhanced their utility in health care. Natural polymers are widely used in the areas of health care for the fabrication of drug delivery systems. As naturally derived biomaterials have limited mechanical strength, their applications as drug carriers are restricted. Therefore such materials are being modified chemically to improve their mechanical properties. Biomaterials for the delivery of drugs or bioactive molecules are showing newer developments with time. During fabrication of these biomaterials, a balance between the physical and mechanical properties together with minimal tox- icity to host tissue must be maintained [1,2]. Complementing synthetic polymers, nat- urally derived biopolymers are on the way of becoming equally important. However, the biomaterials must be obtained with sufficient and reproducible purity and quality. To meet clinical needs in terms of biodegradation, drug loading, and drug release, natural biopolymers may be endowed with additional functional moieties. Because of their exceptional biocompatibility, biodegradability, and nontoxic products of degra- dation, natural polymer-derived materials have been extensively studied in biomedical engineering [3,4]. Biopolymer-based hydrogels have attracted a great deal of interest in tissue engi- neering and drug delivery applications [5]. Despite the known advantages and wide applicability of biomaterials, there are several limitations such as poor mechanical properties and low stability in aqueous environments that restrict their use for biomed- ical applications [6,7]. However, the hydrogels possess a wide variety of functional groups, including hydroxyl, amino, and carboxylic acid groups, which can further be cross-linked and conjugated with cell-targeting ligands. The naturally occurring biopolymers are polysaccharides, and typical examples are chitosan, hyaluronic acid, dextran, pullulan, and alginate. The covalent cross-linkers interconnect molecules, Biopolymer-Based Composites. http://dx.doi.org/10.1016/B978-0-08-101914-6.00001-6 Copyright © 2017 Elsevier Ltd.

However, cross-linking may also decrease the degradability and the availability of functional groups in the cross-linked polymer and changes the rheology of the polymers, leading to subsequent processing difficulties and potential increase in cytotoxicity [6]. For a widely used cross-linker glutaraldehyde, up to 8% has been shown to be noncytotoxic [8]. Because individual polymers alone are not sufficient in providing biomaterials with the desired properties, the use of blends of different poly- mers has been suggested [9]. For instance, porous collagen/chitosan blend scaffolds were developed and treated with glutaraldehyde/genipin to improve their mechanical properties and stability [10,11]. Reduced swelling and decrease in enzymatic degra- dation were found for collagen and hyaluronic acid composite materials without any impact on the cell viability [12]. Similar to the binary blends, a ternary composition of collagen, hyaluronic acid, and poly (caprolactone) was used to generate sponge-like dense membranes using ultraviolet irradiation and carbodiimide coupling [13]. The hybrid cross-linking systems were able to preserve the native structure of collagen, and the inclusion of poly (caprolactone) provided the ability to control the degradation and mechanical properties. This made the sponges suitable for the development of wound dressings and periodontal membranes. Composite materials or composites are engineered materials made up of two or more constituent materials with significantly different physical or chemical proper- ties, which remain separate and distinct on a macroscopic level within the finished structure. Thus composites are always heterogeneous [14]. In any composite, there are two major categories of constituent materials: a matrix (or a continuous phase) and a dispersed phase(s). The continuous phase is responsible for filling the volume as well as surrounding and supporting the dispersed material(s) by maintaining their relative positions. The dispersed phase(s) is (are) usually responsible for enhancing one or more properties of the matrix. Most of the composites target an enhancement of the mechanical properties of the matrix, such as stiffness and strength; however, other properties, such as erosion stability, transport properties (electrical or thermal), or biocompatibility might also be of great interest. This synergism produces properties that are unavailable from the individual constituent materials [15,16]. By controlling the volume fractions of the dispersed phase, the properties and design of composites can be varied and tailored to suit the necessary conditions. Higher volume fractions of reinforcement phases tend to improve the mechanical properties of the compos- ites. The uniform distribution of the dispersed phase is also desirable, as it imparts consistent properties to the composite [15,16]. In general, composites might be sim- ple (homogeneous dispersion of one dispersed phase throughout a matrix), complex (homogeneous dispersion of several dispersed phases throughout one matrix), graded (inhomogeneous dispersion of one or several dispersed phases throughout one matrix), or hierarchical. A hierarchical composite refers to those cases in which fine entities of either a simple or a complex composite are somehow aggregated to form coarser ones (granules or particles), which afterward are dispersed inside another matrix to produce the second hierarchical scale of the composite structure [17]. To prepare any type of composite, at least two different materials must be mixed. However, the interfacial strength among the phases is a very important factor, because lack of adhesion among
