Hydrogels are an emerging area of interest in medicine as well as pharmaceutics, and their physico-chemical characterization is fundamental to their practical applications. Compared with synthetic polymers, polysaccharides that are widely present in living organisms and come from renewable sources are extremely advantageous for hydrogel formation. Furthermore, polysaccharides are usually non-toxic and biocompatible and show a number of peculiar physico-chemical properties that make them suitable for a wide variety of biomedical applications. This book bridges the gap between the preparation of hydrogels and their characterization techniques. It aims to offer a valid support that can help the readers find appropriate keys to open the doors to the complex world of polysaccharide hydrogels.

Integrated circuits transformed our lives, and the potential for integrating biology with devices promises even greater transformations. A key question is how to effectively interface biological and microfabricated systems. Our approach is to “biofabricate” the biology-device interface using biological materials and mechanisms. Here, we review recent progress on three biofabrication approaches: the use of stimuli-responsive materials to recognize device-imposed electrical inputs to direct the assembly (i.e., to electrodeposit) of hydrogels; the use of enzymes to build structure by conjugating and crosslinking macromolecules; and the use of genetic techniques to engineer proteins for assembly. We further illustrate how these biofabrication approaches enable the biofunctionalization of previously fabricated microfluidic devices and suggest the potential for lab-on-chip analysis and the creation of experimental devices to study complex biological systems. We anticipate that the complementarity between biological and technological fabrication paradigms will provide broad opportunities to build structures that couple the power of electronics to the versatility of biology.

Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.
