Hydrogels, as three-dimensional polymer networks, are able to retain a large amount of water in their swollen state. The biomedical application of hydrogels was initially hampered by the toxicity of cross-linking agents and the limitations of hydrogel formation under physiological conditions. However, emerging knowledge in polymer chemistry and an increased understanding of biological processes have resulted in the design of versatile materials and minimally invasive therapies.The novel but challenging properties of hydrogels are attracting the attention of researchers in the biological, medical, and pharmaceutical fields. In the last few years, new methods have been developed for the preparation of hydrophilic polymers and hydrogels, which may be used in future biomedical and drug delivery applications. Such efforts include the synthesis of self-organized nanostructures based on triblock copolymers with applications in controlled drug delivery. These hydrogels could be used as carriers for drug delivery when combined with the techniques of drug imprinting and subsequent release. Engineered protein hydrogels have many potential advantages. They are excellent biomaterials and biodegradables. Furthermore, they could encapsulate drugs and be used in injectable forms to replace surgery, to repair damaged cartilage, in regenerative medicine, or in tissue engineering. Also, they have potential applications in gene therapy, although this field is relatively new.

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.

Fungal nanobionics has great prospects for developing new products with industrial, agriculture, medicine and consumer applications in a wide range of sectors. The fields of chemical engineering, agri-food, biochemical, pharmaceuticals, diagnostics and medical device development all employ fungal products, with fungal nanomaterials currently used in a wide range of applications, ranging from drug development to food industry and agricultural sector. The fungal agents emerge as an environmentally friendly, clean, non‐toxic agent for the biogenic metal nanoparticles and employs both intracellular and extracellular methods. The simplicity of scaling up and downstream processing and the presence of fungal mycelia affording an increased surface area provide key advantages. In addition, the larger spectrum of synthesized nanoparticle morphologies and the substantially faster biosynthesis rate in cell-free filtrate (due to the higher amount of proteins secreted in fungi) make this a particularly enticing route. Understanding the diversity of fungi in assorted ecosystems, as well as their interactions with other microorganisms, animals and plants, is essential to underpin real and innovative technological developments and the applications of metal nanoparticles in many disciplines including agriculture, catalysis, and biomedical biosensors. Importantly, biogenic fungal nanoparticles show significant synergistic characteristics when combined with antibiotics and fungicides to offer substantially greater resistance to microbial growth and applications in nanomedicine ranging from topical ointments and bandages for wound healing to coated stents.

Chitin, poly (ß-(1?4)-N-acetyl-d-glucosamine), is a natural polysaccharide of major importance, first identified in 1884. It is the second most abundant natural polymer after cellulose and exists largely in the marine crustacean. Chitin occurs in nature as ordered crystalline microfibrils forming structural components in the exoskeleton of arthropods or in the cell walls of fungi and yeast. The most important derivative of chitin is chitosan, which is obtained by partial N-deacetylation of chitin in the solid state under alkaline conditions (concentrated NaOH) or by enzymatic hydrolysis in the presence of a chitin deacetylase. Because of the semicrystalline morphology of chitin, chitosans obtained by an alkaline reaction have a heterogeneous distribution of acetyl groups along the chains. Studies on chitin and chitosan have been intensified since 1990 because these polysaccharides show excellent biological properties such as biodegradation in the human body, and immunological, antibacterial, and wound-healing activity. In recent studies, especially, chitosan has been found to be a good candidate as a support material for gene delivery, cell culture, and tissue engineering. Therefore, chitin and chitosan are receiving greater attention as novel functional materials. Despite their interesting biological properties, utilization has been scarcely developed. This review book is a comprehensive introduction to the bioscience and biomedical applications of chitin and chitosan. This review book covers the synthesis and biological properties of chitin and chitosan derivatives and their applications in drug delivery, medical and biological fields. This review book also covers almost all the important findings in these fields and explored these results clearly. The main importance of this review book is to know the chemical and biological properties of chitin and chitosan. These broad ranges of topics that are systematically discussed in this review book will be helpful to carry out more innovative researches in chitin and chitosan in the near future. This review book contains seven chapters included with the various topics of current research interest. Chapter 1 is focusing various methods of preparation of water soluble derivatives of chitin and chitosan. Moreover, the potential applications of these derivatives in the various fields such as drug delivery, food, cosmetics, tissue engineering and environmental is also discussed. In Chapter 2 are reviews the various methods of synthesis, properties of the chemically modified chitosans and their applications of the chemically modified chitosans derivatives for controlled drug and non-viral gene delivery. The knowledge of chitosan scaffold preparation and their characterization and biological activities, which are reported in recent literatures, are discussed in Chapter 3. The Chapter 4, the developments of chitin and chitosan interfaces for the applications in biosensors, microarray, cell arrays, micro fluidic devices and bioimaging are focused. The recent research and development of chitin/chitosan based biomaterials for potential application in orthopedic or bone and cartilage tissue engineering is reviewed in the Chapter 5. The chapter 6 is focusing on the various types of chitosan derivatives and their use in various tissue engineering applications namely, skin, bone, cartilage, liver, nerve and blood vessel. In chapter 7 is focusing about the production and properties of chitin and chitosan obtained from crustacean and fungal sources and their applications in medical and biological sectors are discussed. This review book explains that the advantage of chitin and chitosan over the other polysaccharides. As described in this review, the chemical structure of chitin and chitosan allows specific modifications at their reactive sites, without changing the bulk properties. Specific groups can be introduced into their reactive sites to design polymers for selected applications. Since the biological properties of chitin and chitosan are valuable for medical applications, the developments in these filed can be considered as valuable extensions of the use of chitin and its derivatives. I expect that this review book will be helpful to the people, who are interesting in chitin and chitosan research. I warmly thank the authors for their efforts in producing such informed and enlightening exposition on these topics in chitin and chitosan. Finally, I acknowledge the staff of Research Signpost (India) for their patience and assistance.
