Book Description :

This volume presents the recent developments on the biomedical applications of chitosan and its derivatives. Chitosan exhibits unique properties such as non-toxicity, biodegradability and biocompatibility. Since its chemical structure and properties can be easily modified, it can be an ideal candidate as a biomaterial. Consequently, chitosan and its derivatives are being developed in different forms such as nanoparticles, micelles, nanofibers, hydrogels, films and 3D porous materials for various biomedical applications, ranging from drug and gene delivery to tissue engineering and regenerative medicine. The chapters of this volume focus on the potential use of chitosan and its derivatives as a hemostatic agent, tissue sealants, tissue engineering scaffolds, delivery carriers for bioactive molecules in bone tissue engineering and wound dressings. Some chapter’s deal with recent advancements of chitosan-based biomaterials as a drug, gene and transdermal drug delivery carrier. In addition, the volume focusses on the prospects of chitosan-based systems for the treatment of cancer, eye and other infectious diseases. The volume will be of interest to material scientists, chemists and biotechnologists by providing a better understanding of the physicochemical and biological characteristics of chitosan and its derivatives to develop more appropriate and innovative chitosan-based materials modified for unlimited practical applications in biomedical fields.

Book Description :

Chitosan is a favorable natural polymer for biomedical application for its biocompatible, biodegradable, non-toxic, and hydrophilic properties. It has a chemical structure analogous to glycosaminoglycans, a component of extracellular matrix, indicating its potential bioactivity. However, chitosan's low mechanical strength precludes pristine chitosan scaffolds from tissue engineering. To achieve higher mechanical strength, different reinforcing agents are incorporated into the scaffold system; however, improved mechanical properties are obtained at the cost of compromised structure, porosity, and biological properties of the scaffold. Therefore, pristine chitosan is often preferred over its composites in biomedical applications due to its superior biological properties. This dissertation research presents several novel approaches such as controlling chitosan concentration in scaffold, applying the right temperature gradient, and developing a modular-collector electrospinning system to fabricate chitosan scaffolds with higher mechanical properties and appropriate morphology, pore size, and porosity for different tissue engineering uses, including bone and muscle. In the first approach, we controlled chitosan concentration in acidic solution to increase the crystallinity of chitosan scaffolds and thus fabricate stiffer scaffolds. Scaffolds of increased chitosan concentration, i.e., with greater mechanical strength, showed efficient bone tissue engineering with improved adhesion, proliferation, and osteogenic activity of MG-63 osteoblast cells. In the second approach, we applied appropriate temperature gradients to control pore size and porosity of the scaffold by regulating the rate of ice crystal formation in chitosan solution. Thus, we produced uniaxial tubular porous chitosan scaffolds with pore size and mechanical properties comparable to those of native skeletal muscle tissues. These scaffolds demonstrated the ability to align muscle cells, guide and promote cell fusion, and produce thick myotubes. In the third approach, we developed a novel portable electrospinning system with a modular-collector to control scaffold shape. This approach produced chitosan-based aligned nanofibrous cylindrical, tubular, and membrane scaffolds for different tissue engineering. In a model application, muscle cells cultured on chitosan-based cylindrical and tubular scaffolds showed their effectiveness in producing highly aligned and densely populated myotubes required for muscle tissue engineering. In the fourth approach, we developed a novel hybrid substrate in which a stripe-pattern chitosan substrate, several microns in thickness, is overlaid on a chitosan-based aligned nanofibrous membrane parallel to mimic native micro/nano environment. The results from muscle cell culture showed a higher level of expression of later-stage differentiation genes such as myogenin and myosin heavy chain on the hybrid substrate compared to that found on only nanofibrous membrane or stripe-pattern chitosan substrate. Finally, we stacked cell-cultured substrates to produce 3D tissue-engineered scaffold constructs. These findings prove chitosan's effectiveness as a material that can be used to design and develop scaffolds of required native forms with controlled structure, size, porosity, and mechanical properties for different tissue engineering needs.

A natural long-chain polymer, chitin is the main component of the cell walls of fungi, the exoskeletons of arthropods (including crustaceans and insects), the radulas of mollusks, and the beaks and internal shells of cephalopods. However, marine crustacean shells are the primary sources of the chitin derivative chitosan. Chitin and chitosan are useful for various biological and biomedical applications, although they have been limited by poor solubility in the past. Current research focuses on increasing their solubility and bioactivity through molecular modifications. The resulting derivatives are receiving much attention for interesting properties, such as biocompatibility, biodegradability, and nontoxicity, that make them suitable for use in the biomedical field. Chitin and Chitosan Derivatives: Advances in Drug Discovery and Developments presents current research trends in the synthesis of chitin and chitosan derivatives, their biological activities, and their biomedical applications. Part I discusses basic information about the synthesis and characterization of a variety of derivatives, including the preparation of chitin nanofibers.

Book Description :

The modified formulations were tested for their in vitro gene delivery properties and it was found that these ligands improved gene transfection efficiencies significantly. Chitosan nanoparticles were optimized further for enzyme immobilization purposes using sodium sulfate and glutaraldehyde as physical and chemical cross-linking agents, respectively. These particles and chitosan films were used for immobilizing trypsin utilizing several techniques. Enzyme immobilization via avidin-biotin interaction resulted in high immobilization efficiency and high enzymatic activity in different reaction conditions. Additionally, the immobilized trypsin systems were stable and amenable to be regenerated for multiple uses. Finally, glutaraldehyde cross-linked chitosan films were modified with PEG and RGD for their cell repellant and cell adhesion properties, respectively, using avidin-biotin interaction. This method was again effective in engineering chitosan surfaces for modulating cell adhesion and proliferation. In conclusion, using avidin-biotin technique to modify biotinylated chitosan surfaces is a facile method to attach a wide variety of ligands in mild reaction conditions, while preserving the functionality of these ligands.
